I have been searching and searching about this since long before I even got my Touch Pro(well actually AT&T Fuze) and I have stumbled across some information on the subject but not any real definitive answers.
Here in this thread, you can see that the Xperia X1 was enabled for the 1700Mhz network:
http://forum.xda-developers.com/showthread.php?t=427316
In post #377 of this thread here, there is even a screenshot:
http://www.bengalboy.com/modules/newbb/viewtopic.php?topic_id=1107&viewmode=flat&order=ASC&start=370
I know there is a thread in the Blackstone section here and maybe even more.
My question is does anyone think this is possible and do you think it will happen anytime in the near future?
I'm a T-Mobile US customer and I'm dealing with the slow EDGE speeds but would prefer T-Mobile's 3G and I know I'm not alone here.
I think it's definitely something worth doing since it will drastically increase the market for these phones. Increasing the market will increase the user base and the more users, the better the community could be.
Just my 2 cents.
EDIT::
Here is that screenshot of the Sony Xperia X1 with the 1700Mhz UMTS Band enabled:

From what I have been led to believe that a security unlocked Touch Pro is capable of using the Xperia's Radio. If it's capable of using the Xperia's Radio then it should be capable of using the 1700 Band.
This is a project I hope will become a popular topic.
And forgive me for starting a new thread. I know there are many others out there like this but I just figured creating a dedicated thread that was fresh and right at the top was a good idea.
unless I am mistaken and this is the case with other HTC devices it is not the software that controlls which radio frequency it can handle its hardware has to be capable of supporting that frequency which I dont think the Fuze is capable.

The Fuze, hardware wise, is nearly identical to the Touch Pro. Also I read in one of the older threads that the antenna is capable of supporting the 1700Mhz Band because it is so close to the 1800Mhz Band. It's just an antenna.
What needs to be changed are drivers. Our devices have the same chipset as the T-Mobile HTC G1. Why can't we port that radio to the Raphael?
I always thought u could retune the antenna sort of like a radio to make it work on another frequency but I think it would have to be a hardware modification like opening up the device and using jtag to change it

I think what you said is definitely true. The only different, as I understand, its that Pro blocks the 850/1700/1800 when shipped to different countries. Like the one I am using is the HTC Pro that claims to be quad band with all the necessary freq. on board.
Please let me know if there is anything I could help since I want to use mine with ATT 3g if possible
I am a TE major, so maybe I would still some of my knowledge
Thanks
I think my question is:
In the band tab in phone, I could choose the similar settings as AT&T is using, 850+1900, but why is it not going to the 3G icon?
I am researching on this and hopefully could come back with answer.
huh....maybe I need to security unlock this and flash with AT&T radio?
Hey guys sorry to jump into the mix, but i just wanted to say something. My friend at work has a G1 with the G1 data package and i wanted to show him the skyfire browser because he didnt beleave that it played embeded flash videos. at the time i did not have any data package on my Touch Pro so i askekd to use his sim card. When i used his sim card to browse skyfire and Opera the speeds were crazy fast, it could not have been GPRS or EDGE...it was way to fast. So does this play any part in trying to access the 1700Mhz Band.

By default, you should be able to see what connection you have on the rapheal. is it showing an E/H/3G?
Well that was few weeks ago so i cant really remember which it was accessing...but i know the speeds of Edge and Gprs and that was not it. maybe it was hsdpa or 3g. with edge or gprs playing video in skyfire gives you that lag or constant buffer, whatever i was on that day was fast, very fast..even my friend said it moved faster than his G1 using 3G.

This would be awesome, I am tired of EDGE speeds when there is Tmobile 3G signal in the places I am at. I have a G1 as well but don't use it because they detect IMEI and won't let me use data if I don't specifically have their G1 DATA package. Weird how in the picture it is 3G only and no GSM to fall back on. Too bad my device is not security unlocked.

Yeah there were other photos that displayed the GSM options but I only copied this one.
Yeah I'm not security unlocked yet either but I plan to get unlocked as soon as either Oilpro PMs me back or I get the money to purchase the security unlock...
I just don't understand why he's charging for all of this. Back in the day when I had a Wizard(T-Mobile MDA) this was all free. I guess different time different people different way of working...

yep, I am waiting for his kindness now.
the issue we are facing is not hardware. I think it bares in the radio stack that the hardware receives. As the specs they are, the HTC Pro is identical to ATT Fuze, and it should be able to discover all freqs 850+1800+1900+2100. So there must be something in protocol that prevents us to use the 3g network.
I am gather evidence that this is doable and once Olipro would be kind enough to help my security unlock this, I will start digging in.
Thanks
EDIT: OK, just got pm from Olipro, no luck on free unlock. Guess I need to find some money to pay on this now
UMTS 850MHz
There are people already working on this here :
http://forum.xda-developers.com/showthread.php?t=420865&page=40
I think this would also answer whether or not the 1700MHz would be usable also.
Cheers
Sorry to disappoint, but 1700mhz won't be possible unless HTC releases a UMTS-IV version of the Touch Pro. The UMTS radio is not like the GSM radio (which was unlocked on the Diamond to give it quad-GSM).
This was covered at great length in the X1 forum, but the 1700mhz option you see on the prototype X1 is a software oversight. If you read the BengalBoy thread, you will see that he was unable to connect to Tmobile's 3G network regardless of the setting. That's because the X1 radio simply does not have UMTS-IV (1700/2100mhz) support, and it cannot be "unlocked".
The reason a "UMTS (1700)" option exists in the first place is because Japanese carrier e-Mobile uses UMTS 1700 (band IX, which does not use 2100mhz and is therefore incompatible with Tmo US 3G). Moreover, if it was really meant to support Tmo 3G, the option should read "UMTS (1700/2100) + GSM (850/1900)".
If you search Kaiser forums, you can find a CAB that adds the "UMTS (1700)" option into WM, but it is intended exclusively for e-mobile subscribers and does nothing for anyone else who does not have a UMTS-IX (e-Mobile) phone.

Yes i am very sure i was not using wifi, only my friends G1 Sim card with the $35.00 G1 data package. wifi was not on as i only powered the phone after putting in his Sim card. i will do another comparison tomorrow when i see him at work. but i do think using the better data package does something. if any of you guys have friends with G1's and the G1 data package ask to so a test using your Touch Pro and reports the speeds you browse at or the data rate.

I have been reading all of the threads and posts concerning the 3g issues. I cant decide what the real situation is...I have read that people have flashed a pre release fuze with some of the wwe roms, but never has anyone given a straight answer that the "Fuze" even gets 3G or 3.5G (I miss it dearly!) So just a few direct questions...does a "Fuze" pre release get 3G now...and if so, does it get it with the other roms? Is it a imei lockout or a device lock or what is in our way of success on this matter? If the fuze is getting it now, cant we flash the TP with the software in the "pre release" Fuze? I know that I took my 3G (was getting 3.5G in my kaiser HSDPA) Sim and put it in my current "dream phone" after spending 800 on the EU version I have been let down severely by HTC! Does anyone know if its software or hardware? thanks in advance!

yes the fuze software has been flashed and no it doesnt get 3g. the in the elite project thread they say that it is more complex than just putting on software or radio firmware. I am in the same boat as you with the same investment as you so I am looking for a solution. We have to prepare ourselves for the possible negative outcome of impossability. It is still not known if it is a hardware limitation or not yet. The elite tem will figure it out though.
I think he's asking if a "Fuze" (the hardware, not the ROM) gets 3G, not whether the Fuze ROM on a Touch Pro gets 3G. I have had the same question - it isn't clear that the one person who had a Fuze (pre-release AT&T phone) ever actually got 3G.
The pre-release fuze DEFINATLY get 3G in the US, this is clear from the posts in the threads already in place on this topic.

ok...enough of the sarcasm...
ok...so here is our challenge...What is the difference! side by side the rom, side by side the phone and lets figure this out! What am I missing here and why does everyone have to be so uptight about it! Cant we all just have 3g and 3.5G?
What was the difference in the Diamond? I have read that the FCC just APPROVED the FUZE (yes with 3G as the picture shows!) what was the model number of the phone? did anyone tear it apart yet? has anyone torn apart their b.s. non 3 g version (hell I will do it if you send me the FUZE!)
What did it take to get 3G on the diamond? I bet it isnt that different...
sorry just getting annoyed and impatient with my POS 800$ slow a$$ phone...

Well, it's fine that you're frustrated, but before you come in here expecting answers, read what's already been posted. I won't repeat everything that's been said about why 3G can't work on the Diamond or Touch Pro, but it's been exhausted. They've tried changing ROMs and radios, not as simple as that, they're digging deeper into it to see what they can do as far as getting 3G on the European Diamond in North America but it's not looking too good so far.
I also found...
Telstra in Australia offers what they call "Nextg" which looks the same as HSDPA in US (3.5g) on 850MHZ. I browsed their site and couldnt find any Touch pros, only the diamond. I wonder if they are going to show a newer release date than ATT? Anything I can do to help in this project, please let me know. I am an eet and have been playing with cellphones since the first brick. I know my way around anyphone...and I am not afraid to tear down this TP! anyone have any ideas?
thanks
boomin
The Telstra Diamond works on AT&T 850mhz UMTS band, but not 1900mhz. Considering the US Diamond is available now, that point is moot. As for the TP, the rumored release is like 3 weeks away for AT&T, I think we can wait until then.
wow...
kinda seems like we are "over complicating" this process...No one ever wants to answer my questions, I have spent endless hours on this website, so once again, we know its one or the other, hardware or software, can we at least agree on this? So obviously the FUSE pre release is getting 3G is it identical hardware? Havent seen this one answered anywhere...and if it is, why cant we flash the software from the Fuse to it? What am I missing here?
thanks

If you haven't found the answer, you haven't searched enough, NO the Fuze is not the same hardware. RAPH110 = Fuze, RAPH100 = European Raphael. Do we know if the hardware is the same as far as radios go? No, we have no clue. There are developers who know more about this than either you or I could comprehend working on the issue, if you think it's so simple, flash a European Touch Pro yourself and see what you can get.
The australian version of the touch pro is also 3g enabled. my friend works for ms and has just ordered me one today. should see it on friday. it is able to connect to the 3.5g frequencies.

Indeed, but as we talked about before, it would get 850mhz 3G here in the US but not 1900mhz. The bigger issue is that the European/Australian versions can't get the same frequencies as the US uses for 3G... We're "different" here in the States.
is 3.5G 850 or 1900?
anyone know?

HSPA is run along 3G, in areas where AT&T uses 850mhz, it's 850mhz... In areas where they use 1900mhz, it's 1900mhz... All of this information is VERY readily available if you were to search and learn more about the different UMTS frequencies. No one is going to take you by the hand and teach you everything you need to know about phones.
Its not the same hardware. Case in point, my Touch Pro has a forward facing camera for video calls. The Fuze will not have this. I'm not sure, but it wouldn't surprise me that the Fuze has the "push to talk" button as well.
On the internals... while it might not be radically different, the ICs might be slightly different. It is not uncommon in the IC world to sell bondouts of the same chip, with certain features enabled/disabled. It would be the same basic chip, so 99% of the software would be the same. Just on one chip, you could access certain features and in others you couldn't.
Making ICs these days is very expensive. I can make a quad band 3G chip, and sell it to several markets... a Euro flavor (where use is disabled), a US flavor (where Euro is disabled) and a true quad band (where everything is enabled)... and sell them at different prices. Its often cheaper (especially on low volume or complex parts) to do it this way.
Sometimes these bondouts get different part numbers (even though if you look at the die, its the same... just a packaging change or a fuse change) sometimes companies will give them the same name and you can't tell other than reading some internal register ID.
Like I said, not sure this is what is going on with the Fuze/Touch Pro... but it is one possible explanation for how you could have a "common platform" with hardware limitations.

I don´t have many hope on getting 3G in Euro TP at 850Mhz... Is almost evident that there is a hardware limitation for that (people with a lot of experience like Elite Project team have been working on this without success yet)... I don´t know what the "History" on HTC devices could tell us about ( is there a similar experience on other devices in the past?).. Dudes... I really started to thinking on sell my Raphael

First things first, yes it does have push to talk, I remapped it when I had it because PTT is $4.99 a month (was $9.99 when I had the Fuze) and I don't need it. Also correct in the fact that it had no front-facing camera, and that may be enough for them to change the hardware from RAPH100 to RAPH110.
Next, that's what everyone is hoping for, similar internals to get all bands of 3G, and the geniuses are trying to break down the software and see if there's a way to crack into that quad-band UMTS possibility. I'm not sure how close they are or what chances they have, but then again, I don't even know if they know what chance they have. They're doing all they can, so it's just frustrating to see people jump in here and demand info without taking the effort to look around... The answer to all of the questions of "why can't you just" and "isn't it as easy as" is this... If it were that easy, all of the people who spent $1,100 on their Touch Pro would have 3G in the United States. They don't, but there are people working hard to change that. Just sit tight and wait for information to come, I promise it will be ALL OVER the Raphael forum once 3G is available for the Euro Raphael (if ever, cross your fingers).
demanding?
No, not at all, offering services to open phones (i am more hardware based than software) But I also understand that what we are trying to do has been done...the fuse works, the TP Euro doesnt. I am the manager of a shop that I have employees tell me "its not possible" all day, then I teach them how to do it or at least another way of doing it. So dont take offense, we are all just trying to help each other out...Its obviously not simple or it would be done. But what makes all you guys any better than the rest of us, because we dont have time to spend 5 hrs a day researching all the threads. Before I opened this thread, I spent 3 days reading. I read ALL threads...and to have you guys mock me like I am an ignorant because I dont spend all day everyday reading is ridiculous...

I know the reverse is true. Verizon LG v10 comes unlocked and putting in a T-Mobile sim card works. I have heard people having small issues with 4G LTE calls or extra battery usage, but everything works as both phones share all the same bands except for one.
I love the LG v10, but not having root is driving me a little mad. I've never not had a rooted phone since I got my first smartphone the original Motorola Droid with the slide-out keyboard (and it doesn't look like that will change anytime soon on the Verizon version, if ever). Although LG has a TON of customization stock, I miss the little extras root gives you. At this point I'd be fine with just root access and not even worry about custom roms or kernels.
I'd like to sell my Verizon LG v10 and buy the T-mobile LG v10 H901 so I can have the best of both worlds.
IS IT POSSIBLE?
I would like to know as well

If I'm not mistaken, Verizon runs on CDMA and lte, tmo is GSM and lte... But most phone now by law must run on all available technologies... Bandwidth might be off a little, but for the most part have to be compatible... This is why, when in network settings, it gives options for CDMA, even though tmobile can't use it... It all has to do with the deregulation of cell service laws they passed a few years back... In layman's terms, they have to allow phones and networks to be compatible (1) for e911 services, and (2) for phone and carrier portability.

Zdeuce2, WCDMA is not the same as CDMA. It is a 3G technology used on GSM networks. The CDMA equivalent is (was?)EV-DO and later, SV-DO.
Unless Verizon has moved on from CDMA as a whole for voice (they might have, I'm not sure) then compatibility will be questionable.
@ZDeuce2, what @LvDisturbed1 said.
WCDMA has nothing to do with Verizon's CDMA. WCDMA is one of the signaling technologies within the UMTS specification, old-school 3G stuff.
In the context of the radio mode selector on our phone, "WCDMA" denotes UMTS/HSPA/HSPA+/HSPA+DC (basically anything that isn't GSM+GPRS/EDGE or LTE).
In other words, the selector values can be thought of as 2G ("GSM"), 3G ("WCDMA"), 4G ("LTE").

The answer is yes, a T-Mobile LG V10 will work on Verizon. However, Verizon actively black lists any phone that is not purchased directly through Verizon. Purchasing an iPhone at an Apple store often runs into this exact same issue. Verizon's poorly trained customer service reps are unaware that Verizon has transitioned to all calls, text and data across LTE in major cities and most outlying areas and insists that the T-Mobile H901 must run on CDMA to connect (false), H901 is not compatible simply because the Verizon employee is told to say so by corporate.
I had filed a complaint with the FCC. Verizon issued a generic response saying that all of "Verizon's" phones are unlocked from purchase and that only approved Verizon devices will function on their network. The FCC was satisfied with this generic response and closed the case. If the FCC continues to receive these complaints, eventually they will make a move in our favor.

I've never not had a rooted phone since I got my first smartphone the original Motorola Droid with the slide-out keyboard (and it doesn't look like that will change anytime soon on the Verizon version, if ever). Although LG has a TON of customization stock, I miss the little extras root gives you. At this point I'd be fine with just root access and not even worry about custom roms or kernels.
I'd like to sell my Verizon LG v10 and buy the T-mobile LG v10 H901 so I can have the best of both worlds.
IS IT POSSIBLE?

No, it is not possible, because the T-mobile variant does not have CDMA modem/radio.
Not possible, as others have stated, if it was a Verizon on T-mobile yes because it has both CDMA & GSM radios, T-mobile variant is lacking that CDMA radio.
Hi, just to share results of my research on dual-SIM, simultaneous 4G/3G capable phones.
Do note that there are confusing and ofttimes purposely misleading terms; there are differences between:
the use of FDD-LTE vs. TD-LTE (sometimes misleadingly referred to as "dual LTE")
the ability to switch the "primary SIM/slot" (which has LTE/4G+/4G/3.5G/3G capabilities) with the second/secondary slot without physically swapping the SIM cards (refer to misleading/misinformed information within the OneNote notebook as linked, from no less than one of Singapore's leading telcos)
the ability to simultaneously maintain a 4G/3G connection on both SIMs
Before we start seeing responses in this thread from people asking:
why would you need 2nd SIM to be on 3G at the same time?
simply because there are countries that:
will be shutting down their 2G networks (e.g. US, AU, SG)
have service providers that do not run 2G (i.e. GSM) networks at all (e.g. CA, JP, KR)
why would you need two data connections?
There is a difference between: data connections and voice connections over 3G; if your phone is currently on LTE/4G+/4G and both your handset or your service provider/current service cell tower is not VOLTE-capable, make a phone call and you will note the connection "drops" to 3G (voice).
(caveat: there may be some people that want dual/separate data paths for different apps, but I believe those to be in the minority and not the target/purpose of my research)
The "crop" of "current" generation dual-SIM capable phones in wide-spread markets from the "big guns" (e.g. LG G5, Samsung Galaxy S7 and A 2016-series) cover points #1 and #2, but fail on point #3.
Legend:
highlighted in green background: arguably best in class
highlighted in red background with white text: arguably worst in class (or does not meet the needs of this article; i.e. "4G + 2G only")
red text: warning/of detrimental note
"question marked": unsure/unchecked
For the bands and the countries, that is for my internal reference only, covering most of the countries of my concern; please use that as a guide; I will not entertain requests to add more countries (as it will be a herculean/endless task).
Do note the table is incomplete (those with question marks); particularly I stopped bothering about other aspects if I confirmed it was not simultaneous 4G/3G capable. If you know of any other simultaneous 4G/3G-capable phones, please let me know to add them, but please stick to "current" phones (i.e. announced/released from 2015 or preferably mid-2015 onwards) and please also provide at least two other "official" references confirming said capability (and please do not use two "sources" that circularly-reference each other or the same "source").
NOTE: I have not stated nor verified VOLTE, either on SIM #1 or switchable primary, which is another point of interest for me; if you have any information, please let me know as well.
Thanks!
P.S.: Whereas I have seen quite a few direct edits, corrections and contributions, someone (eventually) deleted the entire page. It has been restored but made read-only for now; please PM me and I will provide an editable link.

Yes, as of current, my research shows exactly that. For the record, I have personally tested the S7/Edge, Z5 Premium Dual and G5, and now own two Mi 5 Pros... The Mi 5 Pros work beautifully, except for:
irritating CN bloatware (and Mi App Store stubbornly sticking to showing CN instead of EN despite language settings)
Xiaomi's framework overriding and interfering with standard Google framework (in the name of their "optimisation", which I have turned off with little detrimental effect overall)
stupid, self-serving "official" forum (en.miui.com; but that is a rant for another thread in another sub-forum)
I will leave my "user's review" for a separate post in a separate thread in the correct sub-forum another time...

I will try to clean it up and also update it... I will try to keep it updated as long as it remains relevant (i.e. when most leading phones are still claiming dual-SIM capabilities but remain 4G+2G only)...
To be added: the Xiaomi Mi Max and the "new" Sony X and XA series (which appears to be near launch here in SG)...

I suppose phones being released after the mi5 in China could all copy this 4g/3g capable tech.
We might see a number of choices later this year, Q3 or Q4.
There is no news with further release of a true dual 4G or 3G phone, probably too costly and a power drain.

Not sure if the Mi 5 counts as a "true" dual 4G/3G phone - that depends on your definition of "true". However, as mentioned above, I may confirm that the Chinese Mi 5 supports both SIMs to be on a LTE + 3G network.
I can confirm that the Sony Xperia Z3 Dual D6633 only supports 4G + 2G as I own this phone.
Sony Xperia X Performance supports 4G+3G, I can confirm this.
The OnePlus 3 has been confirmed by user reports to support 3G on the secondary SIM slot as well.

majority of the dual sim supports 4g and 3g in sim 1and 2, but does it support 4G in sim 1 and 3G in sim 2 simultaneous.
Yes, that is what I'm talking about. You can have the OnePlus 3's primary SIM card registered on a 4G or 3G network while the secondary SIM will still register on 3G simultaneously. Let's call this dual-3G capability.
Any Confirmation that the Mi Max supports 4G/3G like the mi5 does? Or is it like the Redmi note 3 pro 4G / 2G combo?
There's a discussion in another forum at hardwarezone, but I'm not yet allowed to post links.
What I can read out, the capability is requires both hardware, i.e. Qualcomm Snapdragon 820/823 Qualcomm Snapdragon 617/625/650/652, as well as software.
The following should according to the link above, support one sim card on 3g/4g (voice/data) and the other sim card (2g?)/3g (voice only) simultaneously.
Of course only counting the dual sim versions.
LeTV LeEco Le Max 2 (Qualcomm Snapdragon 820)
Oneplus Three (Qualcomm Snapdragon 820) - confirmed
Sony Xperia X Performance (Qualcomm Snapdragon 820)
Xiaomi Mi5 (Qualcomm Snapdragon 820) - confirmed
Xiaomi Mi Max (Qualcomm Snapdragon 650)
Xiaomi Redmi Note 3 Pro (Qualcomm Snapdragon 650 Snapdragon) (un-officially - Need to un-lock and flash modifed rom)
Zenfone 3 (Qualcomm Snapdragon 625) link in hardwarezone thread
Zenfone 3 Ultra (Qualcom Snapdragon 652) link in hardwarezone thread
ZUK Z2 pro (Qualcomm Snapdragon 820)
In another link I can read confirmation at a conference of:
Moto G4 (Qualcomm Snapdragon 617)
Moto G4 Plus (Qualcomm Snapdragon 617)

Xperia X Performance is not 3G/Dual capable
This page on Sony's website http://support.sonymobile.com/global-en/xperiaxperformancedual/userguide/Selecting-mobile-networks/ list these valid configurations:
One LTE network and one GSM network
One WCDMA network and one GSM network
Two GSM networks

No worries... the link is from the global Sony support site so I don't think it's NZ specific - and as most of our phones are AU market devices anyway it shouldn't be related to band support... The fact that Sony has taken the trouble to publish this info suggests that it's likely to be accurate, however it wouldn't be the first time an OEM's support site has published misleading information.

It's not possible to post screen shots, there is no way to show any indication for the dual 3G or 4G+3G simultaneously on the same screen shot, you just have to take my word for it.
dual 4G(LTE) is not possible, if this is selected a pop put will state LTE is only selectable for one sim card socket only.

That being said.
As I don't have a 4G sim, I have set both sim in settings for WCDMA only and I can make or receiver calls from either sim, from a friend it has also been confirmed working in japan where 2G (GSM) doesn't exist, that sim 1 is used for calls and sim 2 used for data, at the same time the V10 was also used in Japan, where sim 1 is usable, and sim 2 does not receive any signal, as the V10 is only 4G or 3G+2G.
The phone is the Hong Kong Version XP (F8132), do note the Xperia X and Xperia XA (Ultra) does not support this feature.
Update, I also think the Samsung Note 7 also supports the same feature, but can't confirm exactly if this is correct.
I just got a BlackView BV9000 Pro in the mail. I stuck my SIM card in it and its being read, I can see my contacts and phone number from it. But its not able to log into my network for whatever reason.
I took it to the ATT store to have them verify I had the correct APN and they made a new SIM for me, but it still didn't work for them either.
I've also noticed the boot up screen shows on boot, then waits for me to unlock it, then in splashes again before waiting me to unlock it a second time before it goes to the home-screen. This gives me the idea that the phone might be DOA or the ROM might be corrupted.
I am in Orlando, FL and just got my Blackview BV9000 in the mail and have the EXACT same problem. I too am with ATT and tried switching SIM cards and all the correct APN info....any luck solving this? Thanks.

I called AT&T again and spoke with someone more willing to help. It appears we are the earliest of adopters here. Their system just doesn't recognize the phone because they've never heard of it.
Engineering said they would be researching the phone and adding the model to the network.
Give them another call and get yourself in the queue to get it added.
10-4, I will call them today....any idea how long this will take? Thanks, at least I'm not in this alone, lol!
Please tell me you guys didn't buy that? If the system doesn't have the device then it reg as an unknown device and will still work.
They told me it would take under 2 weeks, that was a couple days ago.
@zelendel I'm not sure what you are getting at. I'm only going by what they told me.
Something about the system defaults to 2g for unknown devices but they have decommissioned all of their 2g network, so I have nothing until they add it to their system .

What I'm getting at is that is bs. I worked for att and know just how this works. And that line is complete crap.
After looking at the specs for that device I'm betting you will still have issues due to the bands needed to get 3g or lte on att. As long as the device supports the bands it will connect automatically to the bands needed. This is how their byod works.
And after looking at the specs. I'm right. It is missing most of the bands needed.

That's not good... I ordered 3 of them....
Bands were checked....still no connect.
Blackview's tech told me to check the bands too...(which I did before purchase), and according to ATT, the phone has the correct bands to connect....ATT uses the following: GSM 850 & GSM 1900....Black view BV9000 Pro has GSM 850, 900, 1800, and 1900. ATT uses the following LTE band frequencies: 700, 1700, 1900, 2100, and 2300........Blackview BV9000 Pro has LTE 700, 850, 1700, 1800, 1900, 2100, and 2600. These are the identical band frequencies my Samsung 8+ has.......thoughts anyone? Thanks!

I really thought it would match up enough to at least connect to the network.
I had the G1 back in the day and made do with 2g on the att network
Specs DO match up...
Yeah, ATT urged me to reach out to Blackview, (which I have)....because according to the phone specs, it should connect "no doubt"....the numbers don't lie, the tech said. They DO match up.....

In your experience zelendel, do you think it would connect to T-mobile (or another) since it appears to have both of their bands listed?

If it has all of their bands then yes. But if it is missing even one then you might run into issues.
This is a lesson that many have forgotten with the availability of global devices. China uses different bands then the states. This means most times devices sold from China will not always work in the states.
I make a habit to make sure all the bands are listed. This way there is never an issue.
I have a BV9000 Pro here and can see the supported Bands (not only frequencies) in the MTK Engeneer Mode ("call" *#9646633# and go to Telephony > Band Mode > SIM1". Maybe this helps you.
BV9000 Pro supports:
GSM Mode: EGSM900, DCS1800, PCS1900, GSM850
UMTS Mode: WCDMA-IMT-2000, WCDMA-GSM-900
LTE Mode: Band 1,3,7,8,20 (only for SIM1 deeper on the tray, not for upper SIM2)
I have the same problem i already sent my problem to blackview, i tried everything *#*#4636#*#* but for some reason my bv9000 pro when i tried to select radio band just dont have any answer... I also tried several apn but still my 4g keep witouth working. If for some reason i fix my problem i let you know...

There is no fixing it. If it doesn't have the bands for your carrier then you are sol. Remember you get what you pay for. When you go cheap you have to make sacrifices.
HEY!!! Two points:
1) When you are checking frequencies of phone and carrier (to see if they match) you need to know the "B" number. For example, there are at least 4 "B" numbers for 700MHz that I am aware of. So if your phone spec says 700MHz, is it B12 700MHz or B17 700MHz or B28 700MHz? Right frequency alone means nothing. Having said that, the BV9000 has ALL the right "B" numbers to fully support both 3G and 4G LTE on AT&T, T-Mobile, and many resellers. All it is missing is 600MHz that T-Mobile is rolling out. But I don't think T-mobile even offers a handset for that yet. So it's as "compatible" as anything you could purchase directly from AT&T or T-Mobile, at the moment.
2) I have owned many Chinese phones. Without exception, they all need to be tweaked a bit when you first unpack them, or they will NOT connect to ANY carrier, even with a properly activated SIM. The process is roughly..... A) Go into setup menus to enable data on SIM 1 (or SIM 2) B) Go into setup to enable ROAMING data for SIM1 (or SIM 2). You must say to allow roaming because when the phone is new, technically ALL networks are "ROAMING". You will get a warning message about roaming data usage being expensive, acknowledge it. C) Power the phone down completely powered off. D) Turn the phone on and wait five minutes. E) Sometimes you have to do step C and D 2 or 3 times before you will get a connection.
NOTE: Before you successfully enable data and roaming data and reboot, you will not be able to make phone calls or send/receive text messages. You will likely get a "no service" message or a signal strength indicator of NO bars. Also, for some few handsets, you MIGHT have to manually input the APN settings for whatever network you are trying to use, even if you have a properly activated SIM card for that network. But even if the SIM card is recognized and APN info is loaded automatically....you still need to enable data and roaming data before you can make phone calls, or try to use the Internet.
Even customer service reps for the various carriers are not aware that Chinese phones need to have data and roaming data enabled before any good, activated SIM will work. So if AT&T told somebody to contact Blackview (for example) that would make sense. AT&T really (honestly) probably thinks that the handset is broken. While the handset COULD be broken, it's probably working fine, after you tell it that 'yes, I want to roam".

Is this a way to get a LTE network in US ?
I heard that the phone needs a Global ROM Network Firmware? is this something that you guys heard? if it does, how and where do I get this firmware?
My Brother in law said this is what Dealer in indonesia do when receiving phones from china, they alter it and download Global Rom network before they re-sale the phone to public.
So I purchased an almost new V30 and got an ATT unlocked phone for a good deal off of ebay. I've been noticing signal issues vs my previous cheapie Samsung J7 and now can't get wifi calling or mobile hotspot to work. Any insight would be fantastic. I haven't rooted a phone in a while so I'm a little leary on that if I don't have to.
I am not familiar with Metro, but I suspect much like ST that their ToS do not allow tethering. It is also doubtful you have native tether with a carrier branded phone. Rooting is pretty easy if you have a PC, quality USB cable, and patience to read and follow the very well written WTF guide, link below. Switching to either stock US998 or an AOSP rom will get you tethering. Liquid Remix is well-regarded by many.

That is my frustration. I get 5 gigs of mobile hot spot included every month. So It's a loss not to have it. Would rooting improve signal strength. I'm certain it's an LG software issue rather than hardware.
My service is over Verizon's towers so it is hard to give you a firm answer. What I can say is that the open market US998 is rated for service on ATT. US998 firmware will rid you of the carrier dongles and bloat. That said, there are some quirks about signal strength and sms for some cross-flashing cases. Hopefully someone in the know will comment for you. You can also browse the WTF forum.

So I purchased an almost new V30 and got an ATT unlocked phone for a good deal off of ebay. Any insight would be fantastic. I haven't rooted a phone in a while so I'm a little leary on that if I don't have to.

You sure H931 is carrier unlocked? If so, then it's probably already been flashed to US998... That's the way most carrier unlock the H931.
Converted to US998 it will work on T-Mobile/Metro just fine.
You don't need to root, if you don't want.
Well the reason I posted the thread was because yes I have been able to activate it, but my signal is far worse on this flagship phone I'll be at a year-and-a-half old then it was on my Cheapo three-year-old Samsung j7. LTE Discovery doesn't even show GSM on this phone for me. And as I said I can't get any wireless hotspot.
Any idea why I'm not showing any gsm signal on lte discovery?

I would Frankenstein it to US998. You'll get rid of the AT&T bloatware.
Also make sure it's on LTE/HSPA/GSM mode not global mode or something.
It doesn't even show gsm signal. Wish I would have done more research on which variant to buy because it sounds like this att version won't even accept aosp
How do I make sure it is on LTE/HSPA/GSM rather than global?

I don't think mine offers that option. I've actually been reading your thread about the secret menu selections. I think my big concern is with this phone being that it's the AT&T variant from what I'm reading I can't install custom roms I can only go rooted and remove bloatware or go with Factory style ROMs. I really do appreciate all your responses. I think we talked about this but with a custom rom would it address the issues that I'm having with signal? I really don't believe that it's a hardware issue I'm pretty much certain it's that LG has crappy modem software
What do the hardware and software info tabs show in Setttings>System-About Phone?

Rev 1.0 for hardware version. Lg h931.
Software is 7.1.2 AT&T shows that I'm do an update for Oreo, but obviously the phone is on MetroPCS at this point. I'm a somebody that loves to mess with things The Tweak little things here and there so I want to fix the handset because I think the build and the hardware fantastic I'm just frustrated immensely by the fact again not to repeat myself but for the third time that a cheapo Samsung j7 my old phone and my wife's j7 Prime both get far better signal strength. And I'm also immensely confused by the fact that when I look at LTE Discovery it shows nothing under the GSM window.
I suspected as much. So you have a carrier dongled phone from ATT and are surprised/frustrated it doesn't work? What the j7 does is not relevant
Forgive me for being terse, but you have all the information at hand to decide what to do.

I have excellent signal.
Let's forget about custom ROMs for a minute. Let's try to improve your signal. Installing custom ROMs is another discussion altogether and has nothing to do with improving your signal, getting LTE or anything. There's nothing in custom ROMs that will improve signal strength to my knowledge. It's using the exact same radio firmware as stock.
You are on 1-year old Nougat firmware, not the latest most recent available. I would recommend converting to carrier unlocked "open market" US998 firmware -- which is designed to work with ALL North American carriers, while the H931 is designed to work with AT&T -- and then updating to US998 20G (January 2019 security patch). It's the only way you are ever going to be able to update your firmware -- yes, which has newer modems.
You can do that, see if your signal improves -- then you can decide if you want to unlock bootloader and root. Yeah, to unlock bootloader you would have to then temporarily downgrade back to 20A or 20B, but I really want to keep this discussion focused on signal strength for now.

I have LTE Discovery and use it all the time. I have never seen this "GSM Window" you keep talking about. Are you saying you saying you on not LTE or HSPA at all?
What does it show under the "Signals" tab? Give us a screenshot. It should show LTE or HSPA and show dBm signal strength. It should also show closest tower distance and GPS coordinates and how many satellites are available. (I have 12 GPS satellites available with less than 3 meters accuracy.)
Also, when you do a speed test, what is your speed?
These are not my screenshots, it's from another thread where someone was having problems. I just wanted to show you the "Signals" tab I'm talking about...
Mine looks exactly like the screenshot that you posted. So you see there's an LTE chart on the left and a GSM chart on the right? That's what I'm referencing. So I guess my question would be how can I update now that I've got an AT&T phone on Metro

Sorry for some reason it wont let me post my link.
That said thanks. To all of you for your help

But GSM isn't going to show anything, unless you're on GSM. What does LTE show?
The only way you're going to update is to Frankenstein convert to carrier unlocked variant like US998 that has public KDZ releases , which you flash with LGUP. H931 doesn't.
