LG G Pad X 8.0 V521WG on Project Fi - LG G Pad X 8.0 Questions & Answers

So I bought the G Pad X intending to use it on Project Fi (the data only T-Mobile sim). Still sim locked I popped it in and it registered on the network and changed the apn's correctly for me automatically. But as soon as it got signal it would drop showing an X next to the empty signal bars, then get signal again, over and over. Flipping back and forth every half second. I rebooted and it started working great until I toggled airplane mode and it started doing it again. When it works seems random, but it'll work until signal is turned off or lost. Has anyone had similar issues?
Sidenote, it's possible unlocking it may help, but it seems to accept the sim as T-Mobile since there is no error. I put my Verizon sim in for comparison and it flat refuses to acknowledge there is any sim inserted. Anyone wondering, the G Pad X does support two of the Verizon LTE bands so it is theoretically possible to use it that way.
Hoping the Android 7 upgrade (whenever that will be) will upgrade the radio as well.

The LG G PAD X is not a supported device that would work on Project Fi. You can pretty much only use select devices, most of which are Nexus devices, on Fi:
https://fi.google.com/about/faq/#supported-devices
https://support.google.com/fi/answer/6330195?hl=en

This is true of the normal call sim cards. But they sell data only sim cards that only do T-Mobile (no sprint, no calls) that they advertise for tablets and cell phones. They say on their website you can use it in any T-Mobile or unlocked GSM device.

To anyone looking to use the V521WG on FI: Just updated my T-Mobile G Pad X 8 (still carrier locked) to version 10e, and it now works great with Project Fi!
Downside is I now don't have root, but I'll live with that until the dev's figure it out.

I'm looking to do the exact same thing for my parents. They just signed up for Fi and I wanted to get my mother a light weight cheap tablet. (It was between the galaxy A 8 and this one, I think this one is better).
Just to be clear, eventhough it is CARRIER LOCKED, you can still put in a fi sim card (which is another carrier) and it works?
Or did you mean to say the bootloader is locked
I've been looking on ebay and many of them seem like they are locked. If this isnt an issue, that simplifies things

FWIW i got a network unlocked / bootloader unlocked v521 on Swappa and it works great with the fi data card.

I know that doesn't fully answer your question but its a datapoint. There are services online that can carrier unlock devices for $10-30.

T-MOBILE is BLOCKING my P769 sim from the network. Fix?

Hi!
Rooted with cmahendra's offline Lelus method (and to anyone who's done that, my hat is off to you).
**SHORT VERSION**
Sim goes into the L9. I get bars that show network availability, however I am not able to connect/make/receive phone calls.
**DETAILED VERSION**
Starts like this: I have my CM rooted Aria that works a-ok as far as the network. Phone message memory getting full all the time and incoming texts bounce back, with no way of knowing who sent them. Can't have that, so I buy a stock L9.
Sim works. I want to have Wi-Fi calling, which is the *only* reason I bought the L9. Wi-fi calling is not working: call up T-Mo and they say I need to give a 911 address and all will be well. Ok, done.
Sim works. But no Wi-Fi calling still. Call up T-Mo and they say "Ohhh! you need a "3G-B" (I don't think that stands for gigabyte) sim card" Ohhh and what's your phone model etc etc. I tell them "it's a no-brand phone I got overseas," they don't need to know the model: they didn't with the CM Aria. They're clicking settings on their screen other side of the phone while we're talking: I can feel it.
Sim *stops* working. Need a working phone, so let L9 aside and get a stock T-mo S2. Same issue, cell network not connecting.
Let me show THEM! Ha! I'll unlock it. Unlocked the S2.
Sim still doesn't work.
Put the Sim back in the rooted/unlocked Aria? Network works.
What settings do they have in their stock phones that disallow network connectivity, because in the CyanogenMod Aria I have the phone fully works, GPS, tether, etc etc. In their stock-from-T-Mobile phones, network = nada.
Thank you for reading.

What the heck are you asking? I don't see any understandable questions in your message. I see you blowing off steam.
It does look like T-Mobile cooked your sim. You may need a new one.
Call them again and ask for "Customer Retention" through the automated system. Those people are more knowledgeable. A new sim should be free if they killed it.
Also, a data plan is not required for wifi-calling.
T-Mobile will give you a SIM regardless. They are always free.
I'm not sure as I am unrooted, but most carriers block network access via files in the EFS folder. This folder is VERY delicate. Anything improperly changed here can render a phone useless. If the SIM works in another device, it's not the SIM. Have you tried a different SIM in your phone?
Also, if you're blocked from network access, when you make a call, you should be prompted with, "We're sorry, but this device has been blocked from network access." If you do not get that prompt, then there is something wrong with the phone itself, be it software or hardware.
Looks like the L9 isn't registering in their system. Where did you buy the phone, blacklisted perhaps?
As for fried your sim, why does it still work in the Aria.
As for 3G-B, you probably need a newer sim, others call it a 4G sim... They should send you one free or pick one up free at a local tmo..
Thanks so far folks...

You hit the nail on the head exactly clockcycle, it's not registering. Something *in* the phone is not letting it connect, because my sim works successfully in any and every other unlocked phone I have, blackberrys, GMS world phones, the rooted Aria, but in the two "newer-released phones-- the L9 and the S2-- it doesn't work.
Phones are legit. Craigslist and brand new. Worked perfectly until calling T-Mobile for "support". The sim is fine and the goal is to keep it and not get a new one. It works.
My strong guess is that if I put a different rom that is *not* stock, the phone will work fine. It worked fine in the beginning, until I called them to address the wi-fi calling issue and they started poking around in my account, asking questions and clicking on things. I didn't want to address the wifi-calling issue too much because we could go off on a tangent.
You're right kevev, it didn't look like there was a 100% clear question. A lot of story though, to make sure there aren't 50 posts of did you do this and id you do that. A full story gives everyone the most info they need to understand the situation instead of "yo! my phone is not connecting!" which we see sometimes .
So the more clear question is:
"I am experiencing carrier settings *in* my L9 that are blocking me from connecting fully to the network on a perfectly fine sim card, how can I get around these settings and what/where are they."
I think tribalartgod understands what I'm getting at most completely. The inside-the-phone-settings. When the sim is in the phone I have bars, but when going to make a call the screen message is "emegency only". Can't try different sims in the L9 because of the need to cut the sim down. Also the L9 is not unlocked, just rooted. My guess is a de-bloatwared rom is the fix. Looking for answers from people more knowledgeable than me which is most likely all of you. Thanks again!
Craigslist, new, boxed, doesn't gurranty they aren't blacklisted.
BUT, the Aria uses a miniSim, the L9 uses a microSim. Did you cut your Sim yourself? It might be misaligned, cut wrong.
It's less than $2 to get it unlocked..
It sounds like its IMEI blocked dude. This can happen with various insurance or installment plan scams, even to brand new devices. There are options to still use the phone, but you are hosed on T-mobile. I have a blacklisted L9 because the previous owner quit paying his EIP, but it's unlocked so I used it on an AT&T MVNO connected to an AT&T MicroCell (I wanted WiFi calling too, but that won't happen with a blacklisted IMEI). Until you've gone to T-Mobile's chat support and ask the if the IMEI is clean, writing long posts in this thread is futile, and it is pretty clear everybody in this thread THINKS they know what they are talking about, but nobody has simply asked T-Mobile about the status of the IMEI, which takes two seconds.

US carriers and Getting My x829 "activated"

I received my Le max 2 (x829) about 5 days ago hoping my carrier would "support" it. Turns out US Cellulars bring your own phone style plan is incredibly limited, and after about 3 hours on the phone I was told that based on the IMEI number I had given them, US Cellular's (USC) system wouldn't be able to support the phone.
Side note right there - I did notice that part of the "rules" given to me on this were already broken on my Current USC phone and that Both the x829 and current phone share some similarity in IMEI number rhythm (maybe nothing but wanted to note it) IE *405033* on one, and 454050** on the other.
Found some time to research today and have found several XDA members noting that they have their x829's working on T-mobile, even T-mobile through Straight Talk. However, when checking "phone comparability" with either one using the IMEI # that all companies want to know atm I'm given an error.
So My question is thus: How did you; a X829 owner get your phone to work on your desired carrier? It seems AT&T and T-mobile seem to be the go to on this which I'm fine with.
A side question would also be: could I use "xposed" to change the IMEI to something my current carrier would "recognize" / was this what every one else has done?
Isn't US Cellular CDMA? For the Le Max 2 you'll need a GSM network.
I just received my x829. Out of the box VoLTE and WIFI calling worked with T-Mobile (on all official EUI 16s roms). I currently use the MADSURFER and both wifi calling and VoLTE are working.
All I had to do was pick up a nano sim which I activated via phone. I bought the Fire HDX 8.9 SIM from amazon for $4.00.
*Edit MADSURFER ROM link is here https://forum.xda-developers.com/le-max-2/development/madsurfers-21s-eui-5-9-rom-t3497125

US Cellular is listed as CDMA, but all the research I've done before going with the Le Max showed that other GSM only phones like the ONE plus 3t would work on the network based sole on the phones bands support by the phones hardware.
I have plenty of Nano sims thanks to the Straight Talk "phone kit", infact both the At&T and T-mobile ones are in the phone atm. I do appriciate you re-enforcing the notion that VoLTE and Wifi calling work (which would be to my benefit where I live) my fear is that calling and trying to activate the sim will lead the "rep" to ask for the IMEI and again tell me wont work.
@leptdre i'm very leery to try things with out a further explanation, kind of a side effect of the college days.

US Cellular uses the CDMA band 20 (3G) 800MHZ. see: https://www.frequencycheck.com/carriers/u-s-cellular-united-states
I was thinking that the menu was for enabling Band 20 for LTE, but I was wrong. In fact it says: China Telecom's CDMA , china telecom uses CDMA band 20 (3G) like US Cellular.
https://www.frequencycheck.com/carriers/china-telecom-china
I think if you can get US Cellular to activate the service, with this option checked : *#*#9439#*#*, you can get your phone up and running.
I activated mine on Tmobile. Bought a sim from them and activated it online, used the 1st imei number on box, there's 2 imei numbers I assume 1 for each sim slot. After punching it in it knew I was on a LeEco Le Max 2. Rebooted phone and wifi calling appears. Also wife and son have same phone on T-mobile but already had nano sims so they just moved sim to their X829 and that was all they needed to do.

T-Mobile and AT&T are GSM carriers, which means that the sim is the only identification module.
US Cellular, Verizon, Sprint are CDMA carrier, the identification must come from the phone it self. The sim is only use for 4G LTE because 4G uses a standard relying on GSM to identify the customer.

Thanks guys, sorry I work nights so I'm just getting all this... I'll take a look at the videos first.
Will SMS and MMS work over the wifi as well or just calling?

I had a Straight Talk kit from an earlier attempt to use a Zenfone 2... the rep with strait talk wouldn't "force" activate the sim for my area because "no coverage". Apparently my city/town where I will use it the most doesn't have enough coverage From At&T or T-mobile to warrant being able to transfer my number from USC. Going to try "re-upping" the AT&T sim A user on another thread has noted that @ stock on EUI rom wifi calling was still available with At&t.
Edit:
https://www.amazon.com/Fire-HDX-8-9-Activation-T-Mobile/dp/B00L8BYGJQ - decided to go with that as xlCashlx did and try t-mobile... so far out of all the reps I've delt with over the last couple of days, t-mobile's has been more forth coming with information than any of the others.

OP Good luck with T-Mobile
So did anyone tried to use it with Verizon? According to willitwork site should be a go, but someone needs to confirm. For example I am using the Zuk Z2 from China and the 4G on VZN is working like a champ.
T-mobile here. When my x829 arrived, I simply pulled out the sim in my Moto G4 and immediately had service on the le max 2. Didn't even contact T-mobile.

Did it came with the stock rom or some sort of custom one when you bought it, thanks?
It came with the EUI factory rom by letv. Now that I think about it, I never actually tested TMO on that factory ROM. My wife has the x820 and I have the x829, both on TMO and both on different roms.
However, I have flashed the small EUI rom with no problems, plus you can find other user's experiences with TMO on stock EUI and everything I've seen points to good compatibility.
I'd recommend looking thru some of the threads on slickdeals for this phone. There has been a lot of discussion on different experiences with US carriers, mainly from a budget/value perspective. I'm on the walmart TMO $30/mo 5GB LTE plan (pay as you go) and really like it.
https://slickdeals.net/newsearch.php?src=SearchBarV2&q=le+max+2&searcharea=deals&searchin=first
To answer my own question and to advise everyone else that lives in the US and is planning to use the phone on Verizon network, you need to look elsewhere. Let me elaborate, I am getting LTE on the phone right after inserting the SIM card, but voice is not working no matter what, I even made a trip to my nearby VZN store to make sure that they dont have to go and white-list my IMEI or something. To put it in a more polite words, they declined to do anything, even after the fact that I have a corporate SIM that my company pays hundreds of thousands of $ per year to VZN for all the subscribers we have internally, on top of that I had my Zuk Z2 to prove them that, other phones that are not VZN "approved" can work with no problem with both LTE and voice. The last comment from the representative was that there are loopholes and some not approved phones can work, duh, I had the evidence with me, and again they refused to add the LeMax 2 IMEI to their "good" list.
So if you are planning to buy this phone, consider the fact that you will only be able to use it on ATT, T-Mobile and the rest of the GSM providers in the US.

PSA - Unlocked V30 with Verizon & old Unlimited plans...

If you have an old Verizion (USA) unlimited data plan (or perhaps other "older" phone plans) that you've been holding onto AND you plan on buying unlocked phones you may want to read about what I learned today... This is mostly a PSA, but if anyone knows of a way to actually "fix" the issue please reply.
The short version is that apparently the old (original) unlimited data plans are setup to only work with locked down "Verizon" phones. I'm still working out all the ramifications of this and could use some help further down in this thread. What this means is that you can NOT activate a NEW sim card in an "non-Verizon" (unlocked) phone IF you're also on an original unlimited data plan (and perhaps any other older plans beyond a certain date?). You CAN; however, activate a NEW sim card in an OLD Verizon phone and after setup is complete you can then move that sim over to your new phone. This should not be a problem for NEW Verizon phone plans OR locked down phones that are considered "Verizon phones" by Verizon software.
As far as I can tell (so far), activating a new sim in an old phone and then moving to the new phone doesn't cause any issues with your service, but I could use some help testing this out in greater detail to confirm.
Here's my story:
I've been on a Verizon unlimited 4G data plan since they first offered them many years ago. I've remained on this plan through price increases and the removal of unlimited only to watch them return it (I almost switched to a new plan months ago... almost). I used to have a Droid Razr Maxx which got rooted and I enjoyed root for awhile. I eventually upgraded to the Droid Turbo (employee edition) which took a long time to gain root so I simply never tried. I decided I wanted root access again and all the joys that brings so after much research into my next phone I landed on the LG V30 unlocked edition. I got my order from B&H Photo a few days ago. I also decided that I wanted a new sim card as I've always felt my old one was "touchy". Could never put my finger on, but mostly I just wanted to start fresh with the V30.
A couple days ago I went into an official (USA) Verizon store and made my request to get a new sim activated on my V30. I didn't think this would be an issue as they sell V30s and I know others have been running "non-Verizon" phones without issues. The CS rep was supportive of this, but after inserting the new card and trying to activate it the Verizon software on his employee tablet shot back something about "this phone does not support this data plan" (or something similar). He tried to troubleshoot the issue for about 10 minutes, but then gave up since I was able to get the V30 working by using my old sim from my Droid Turbo. I accepted this and decided I'd just try again in a few days.
During this time I had no issues with the V30 using my data or making phone calls. I did eventually "kill" the V30 by exploring the band selection screen in the service menu, but a hard factory restore later and I was up and running again. Today I decided to try and get a new sim card again, only this time I decided to head to Best Buy since they sell the unlocked V30 online. My thought was "if they sell the unlocked V30, maybe they'll better understand my issue with a new sim activation"....
After finding the "sim card expert" I requested we went to work. He pulled our a new SIM, dialed up his Verizon contact number and we waited. Once the Verizon rep was on the phone we continued onto activating the sim only to be met with the same error "phone & plan don't like each other". The Verizon rep was stumped after many trial and error attempts on getting it to go through. My issue was eventually escalated to a tech that had more power to get things working and even he was stumped. After nearly 2 hours of digging into provisions and my account info he informed me that my "old" data plan was setup in such a way that it ONLY allows new activations with "Verizon" phones. Of course he suggested I move to a new unlimited data plan (with all the new fine print and prioritizations after 22GB intact of course, ha). He added that there was nothing he could do to change my plan settings to allow new "non-Verizon" phones. He was supportive of activating the new sim on my old Droid Turbo and then placing it into the V30 though. Once we did that the V30 was up and running again. On some quick tests everything appears to be working as well (would like some help to verify this though).
So there's the info I learned today, hopefully this helps someone else avoid any headaches later. How accurate this info is depends on the Verizon tech on the other end of the phone though as I'm only repeating what I was told. The tech did say that he never ran into this before (as I assume most people simply keep swapping in their old sim cards) and he did add that newer plans and phones shouldn't run into this issue and that it's strictly my old plan causing the hiccups on their system. He did check into moving me to the new data plan for activation and then putting my back into my old plan, but came back with "it's not possible".
Now then... all the above said I could use some help ensuring that my unlocked V30 is working correctly on Verizon with my current phone plan.
I've installed an run "RX Monitor", but what I notice is that I see no CDMA options listed under "operator" or "registered cells" or "Neighbor cells". All I see are "LTE" connections that seemingly only use "Band 13". I've driven between different cities from corn fields to the center of town and any time I check I see only "LTE" and "Band 13". Based on what I've read this seems odd... but I don't know enough about it to say for certain.
What I can say is that I can make phone calls (though they seem to be going over LTE and using HD Voice) and I send/receive SMS and MMS texts. I can go online and download and all the good stuff.
Is there a way to further test my phone? When I run RX Monitor on my wife Droid Turbo I can see a CDMA option and other LTE cells, but her phone does not report enough data to compare (ie, it doesn't list the band anywhere in the data) that I can see.
Is there another program or some other way to test or check this? My concern is that I've yet to see "3G" or "1x" on my V30 and I worry that if I end up in an area with more limited coverage that the V30 will simply not work vs switching to 3G or lower (something my Droid Turbo has done in the past).
Any thoughts?... and thank you.

I know it was a long read, but hopefully it made sense.
With full root access would it be possible to label an unlocked V30 as a "Verizon" V30 in software to trick the Verizon registration process into direct activation?
I don't know. The two have different FCC ID, so that would be one way for Verizon to tell the difference.
On the U.S.Moto Maxx 1225, people could unlock the bootloader, then flash Verizon firmware over it to turn it into a Droid Turbo XT1254 because they had the exact same FCC ID and were exactly the SAME device. Verizon just rebranded theirs as a "Droid Turbo" to pretend it was some kind of exclusive. It wasn't even exclusive in the U.S.!
Until Sunshine came along to unlock the Droid Turbo bootloader (a year after release), the Moto XT1225 served as the "dev" version of the Droid Turbo.

I assume I'm not the only grandfathered Verizon data plan with an unlocked V30... can anyone else confirm that simply moving the sim over from another phone allows the V30 full access to the Verizon network.. CDMA, LTE, 3G, etc?
As I've said so far I only ever seen LTE with 4G. Though I did see CDMA once shortly after activation.. but then nothing
I recently got a Note 8 (at best buy, 300 off,but a down payment, and device payment plan). The sim activated on the Note 8, but my previous active sim was on an Unlocked S8 Plus (g955u1). I then activated the Note 8 Sim on my wife's back up S5, and then put the sim in my S8 plus unlocked. Inhave used the Note yet, because I dont have a glass protector yet and in case I have buyers remorse, I can return the Note 8.
If you have the grandfathered plan (which I do), you jusy simply have to get a 4g Verizon smart phone with a nano sim slot , activate it in there and put it in the Unlovked Lg v30. You should be able to get CDMA and 4g LTE connection.

Hmm I've had the same sim (just shaved down) since my OG Droid. Would this make a difference?
Ooo yeah here we go
Per Verizon's agreement with the FCC when they purchased radio band frequencies, Verizon must allow any compatible device to work on their network. If your device has CDMA and the LTE bands (2, 4, 13) then it will FULLY work. You will be able to make CDMA calls, LTE calls if VoLTE is functional on your device, and use data.
It is true that they are stingy on activation and there is NOTHING the techs can do to activate an unlocked phone. They did't write any code to block it let alone are aware of it. Don't bother even trying. Just get an old Verizon phone that takes nano SIM or go to a store and find an employee willing to activate it in a display phone then give it to you.
I've been using the same SIM for years from my Droid Turbo. It's been in a Nexus 6, Nexus 5x, Moto G4 Play, and an HTC One M8 without any usability issues.

Yes, that SIM card you have is still considered a mini SIM and will not activate in newer phones that take nano SIM.
I shaved down a micro SIM to fit a nano Sim slot. I tried to have it reactivated and Verizon was unable to. I informed the tech that it was actually a micro SIM and he activated it in a dummy Galaxy S3 and it worked.

I know it was a long read, but hopefully it made sense.
With full root access would it be possible to label an unlocked V30 as a "Verizon" V30 in software to trick the Verizon registration process into direct activation?

Verizon and probably the others use the IMEI number to check if it is a VZW or non-VZW phone before activation. Unless you obtained another IMEI number and used it, they can always tell it is a non-VZW phone. But I'm pretty sure that is illegal.
I'm on an unlocked/google Nexus 6. It wasn't purchased from Verizon. I also have an old unlimited data plan. Once a stockish rom comes out for the LG V30 I'll take the plunge and test this out. Hopefully my sim will work in the v30, since it already works with an unlocked phone.
All good info. Thanks everyone.
How could I test the phone though? Is there a way to force CDMA calling vs LTE.... Also... Using RX monitor why would I only be seeing band 13 with no CDMA listed?
I'll update here what I learn comparing a "Verizon V30" vs my B&H unlocked V30. I purchased a second V30 using the Verizon $300 off deal to combine it with the $400 rebate from LG. I know, I know.. it's locked down... but for a cheap backup phone I'm not complaining. I'll run as many comparisons for cellular service as I'm able to.
I know of RX Monitor... hopefully that will confirm or deny that my unlocked V30 is using the network in the same way as the "Verizon" V30.
Any requests or other programs I should use for comparison??
From what I understand, the grandfathered Unlimited has nothing to do with it. As far as I know, Verizon has only activated NEW sim cards on Verizon branded equipment. Once your number is provisioned on a Verizon phone, there is no issue moving the sim between unlocked phones.

THIS. This is what I've always been told the past few years. Recently someone said Verizon had changed their policies and they somehow activated a SIM card on a 2015 Moto X Pure, but I think that was some kind of fluke. I would still use this policy as the guiding principle for control freak Verizon.
AT&T and T-mobile don't care where your phone came from, they'll activate your phone. I'm on AT&T and have never had an AT&T branded phone. I even brought in two Moto XT1225 from other countries; the Moto XT1225 is the "international" version of the Verizon Droid Turbo XT1254. It was also basically a 5.2" version of the Moto Nexus 6. AT&T didn't have the XT1225 in their database. I said call it a Moto Nexus 6, which they did have in their database. BOOM. Activated. Two of them. And not just on AT&T, but AT&T Prepaid, because I own my phones and only want to pay for monthly service not pay an arm and a leg to subsidize some AT&T branded phone I will NEVER buy.
I'm not here to bash carriers (but I will bash most MVNOs), but the CDMA twins Sprint and Verizon are more trouble than they're worth, in my opinion. I want to use a carrier's signal, but I don't want to buy a carrier's locked down, often overpriced, devices. I don't want to have to buy a carrier phone just to be able to activate a non-carrier phone on that carrier. That's ridiculous.
Does the hot spot work out of the box on the unlocked V30 US998 on the old verizon unlimited plan?

yes, it does.
I have the B&H US998 V30+ on Verizon, but I gave up unlimited a year or two ago. Still not on the new unlimited yet.
Are you able to get any VM notifications on this phone?
I only get garbled text messages from Verizon, and there is no VM indication.
I have to check for missed calls and manually call *86 to see if I have any voicemail.
Other than that I think it is functioning fully. However I have never seen a 3G icon in the status bar.
I have a Verizon 4G Network Extender in my house, and I get good 4G at work.

I assume I'm not the only grandfathered Verizon data plan with an unlocked V30... can anyone else confirm that simply moving the sim over from another phone allows the V30 full access to the Verizon network.. CDMA, LTE, 3G, etc?

I am a Grandfathered user with 450 anytime minutes and paying for text messages still. I moved from an LG G4 to an HTC 10 to an LG V30 just fine. Popped the simcard out of my HTC 10 and installed it into my unlocked V30 and it works perfectly. I don't have any wifi calling though and I'm assuming because I'm not installing any verizon apps what so ever. I don't require wifi calling so i'm good. But it drops to 3G when it has no LTE signal just fine and VoLTE works perfectly. Hope that helps you out.

It's the same for me... just messed up text messages. I even tried to source the Verizon Voicemail app, but it refused to install... sooo... I setup Google Voice instead and after some tweaking it's working great, Google AI or whatever even gives me its best translation of the voice mail too in text form so I don't need to listen
The one thing I have noticed with Google Voice and normal voicemail is that if I let the phone ring through Google voice works perfectly, BUT if I decide to swipe the "ignore" or whatever button, then the normal voicemail picks it up. It's kinda nice in a way having two voice mail boxes... but also wish I knew how to fix that issue and force everything to google voice.

So I found out that Tmobile US cannot connect to data and now cannot unlock bootloade

So I recently found out that I needed to get a sim card and connect to mobile data in order to unlock my pad 4 plus and so I thought I could use Tmo's 4g/3g network, went to the store in order to get a nano sim card because my old tablet used a micro sim, then I found out later that there's not even a 3g band for tmo that can connect to the tablet. I could just be dumb to buy the tablet from China but in reality I was going to use to on WIFI only and 4g would be a plus. But since Xiaomi doesn't allow for Mi Unlock Tool to be used on WIFI, I can't even unlock the bootloader, I have a useless sim card and mobile line, and am looking for another way just to unlock this device.
It's disappointing to know that I can't even unlock the device on WIFI.
Please, I would greatly appreciate it if someone can find a solution to unlock the device via Wifi

I'd like to know too. I figured lte meant it could take tmobile, but I'm a bit disappointed. Any work around to get it working for tmobile?
a quick check here: https://www.kimovil.com/en/frequency-checker/US/xiaomi-mi-pad-4-wi-fi shows that it should support at least B5 on the T-Mobile network. But we don't know the band coverage over the country, so you might simply be living in an area without any usable bands.
Looking at this list, we can see that Sprint apparently has 2 supported bands (B5 and B41) so maybe you can try a Sprint SIM? Maybe someone you know has sprint and can borrow you their card? Or maybe Sprint offers a cheap prepaid plan you can use temporarily?

Emergency Calls Only on LTE

Hello!
Can someone please help me with this?
Everything was fine until 2-3 days ago. When all of a sudden I was unable to send text messages or make phone calls. All the while I could access internet without any issues.
If I switch to 2G or EDGE for the Subnetwork, I can make calls and send SMS.
How can I fix this?
Could dropping the phone have caused this?
Dropping could certainly break something, of course, but let's assume that's not it.
What carrier? Is the phone officially supported by them (ie, IMEI matches the carrier)? Are you on their official ROM? Does/did your VOLTE work (before and after the "few days ago")?
Some carriers are switching over to VOLTE-only setups, so they may be testing that to see what works/doesn't before they make it final. In other words, maybe your phone is not "officially" supported by VOLTE on the carrier, which is why it's failing? Without VOLTE, I think text may fail as well (even if you're not actively on a call?)
That would be my first guess. In my case, for example, I was on a US998 phone (per IMEI) running VS996 on Verizon. Since the IMEI didn't match a VZ phone, they refused to say it was compatible (even though it worked fine for many years). The IMEI stuff is a bunch of BS, but that's a whole separate topic... but I wonder if this is what you're running into. It's the carrier's way to force you into "their" device, even though it's not any different from any other variant (when the proper ROM is installed).

Carrier texts should theoretically still work as they are "data". It's the "voice" part of VoLTE that won't work. That's why I can still receive carrier texts on my Galaxy Note 9 with AT&T -- which still has older firmware (so I can be rooted). A few months ago, I lost the ability to make/receive phone calls on my AT&T number when 3G towers were decommissioned in my area... But luckily I have Google Voice number, which also uses "data" (VoIP) so I make/receive all my Google Voice phone calls. (That's been my main phone number for years.)
However, I no longer can make/receive AT&T phone number calls -- which is fine. I switched Google Voice settings to data/Wi-Fi only instead of piggy backing on carrier phone number. Yet, I still receive AT&T texts, which is good because my bank insists on using a "real" (carrier) phone number for SMS security code confirmation.

I'm with a company that uses T-Mobile towers. I connect just fine with 4G LTE, and get reasonably good speeds over it. But when I'm on 4G, I cannot make or receive calls or text. It says Emergency Calls Only.
So far, I've tried everything. I resettled network. I looked for different APN values that may fix the issue. When I couldn't think of anything else, I did a factory reset. (I mean, I wiped Data, and all other partitions in TWRP except for System and SD Card.) There have been no changes.
I'm starting to think the issue may be hardware, I did drop the phone a couple of times the day it stopped working. Though I usually end up dropping the phone once a day or every two days. I can't believe the screen hasn't cracked yet, at all. Could a drop from 3-4 feet on hard surface like tiles damage the antenna in such a way that only 4G data works?
I'm ready to give up and buy a new phone even though I can't really afford it. It would be awesome if I can get this to work.

I'm on T-Mobile towers with the US998. I don't think there is an issue with IMEI. How would I connect to data with 4G if that was the case?
I never had Volte on this phone. I do recall seeing it when I first got it but I'm running stock rooted Android 9.
When I say it used to work a few days ago, I mean it just stopped working at one point. I wanted to make a phone call, and all of a sudden, I couldn't. I noticed then that it says Emergency Only sign, so I walked around the house for about 15 mins to try to get signal. Then I went to my car and drove around, but nothing.
I messed around with Network settings, and figured out that Voice and TXT worked when I switch to a lower 'Sub-Network' setting that says, "GSM / GSPR / EDGE Only".
To get 4G Data back, I have to switch it back to "LTE/Legacy 3GPP multi"
These two are found under "GSM/UMTS Settings", after clicking on "System Select" in "Mobile Networks ".
I want to also mention that my carrier website has been talking about a data migration that would affect phones using their old SIM Card.
When I saw that, I called them and had them send me a new SIM. I thought surely this must be it, but the new SIM works exactly like the old one.
Perhaps the migration or whatever it is they did that required new SIM cards just doesn't work well with my phone? Even though, before putting the order in, the rep I spoke to did check my IMEI and said that my phone is compatible.
Agreed, it doesn't sound like an IMEI issue.
FWIW, I showed a 4G connection on a phone (I don't remember if it was my V30 or a Galaxy S10+ that I was going to replace it with). On that phone, at one point, but there was no actual connection. So, the indicators aren't always accurate. That's why I thought maybe the data isn't really working, and if data isn't working then VOLTE won't work... and with many of the carriers switching off non-VOLTE calling, that could kill the ability to make calls?
In your case, you said data worked... but if VOLTE was never enabled, and the carrier dropped non-VOLTE, then, again, you may lose calling.
In any case, these were my theories. I think you're on top of the situation but I don't have any other ideas for you to try...
Instead of buying a new phone, have you considered installing and setting up Google Voice, as ChazzMatt said? I recently had to do that because AT&T's 3G shutdown meant that I could no longer place or receive calls. My quick guide on doing that is here: https://forum.xda-developers.com/t/...-based-custom-roms-when.4138223/post-87342453
I don't know why you can't also send or receive texts, but the Google Voice app has the ability to do that, so maybe try using that after you've set it up.

There's been reports T-Mobile which is now merged with Sprint has borked the ability for VoLTE/VoWiFi calling on US998 firmware phones (native or Frankenstein'ed). Apparently they only allow it now on T-Mobile H932, whereas pre merger they were happy to give VoLTE and voWi-Fi calling to "US998" phones
First, it was reported with new SIM cards they were distributing earlier this year. Then people who kept their old SIM cards found they didn't work after a forced "security update."
This seems to have also trickled down to the T-Mobile MVNOs.
This is why we told someone else recently they should probably convert their phone from US998 on T-Mobile to Verizon VS996 firmware.
Then get a Verizon sim card or Verizon MVNO SIM card, and activate it in an old cracked screen Verizon phone off eBay, then put that already-activated SIM card into their "VS996" V30.
They will have VoLTE and VoWi-Fi calling.
Alternatively, if you really want to stick with T-Mobile network, you can do what @osprey00 suggested -- which is get a Google Voice number and use it as a tool to forward your carrier calls to it.
You can read his post, see his experiences, and see if this would apply to you.
For ME -- I've been using Google Voice for the past 10 years as my main phone number. I ported my carrier phone number at the time to Google Voice. Then got throwaway carrier numbers (whoever had cheapest plan) but never gave those to my friends. To my friends nothing ever changed. I've had the same "number" for the past two decades.
But within the past couple years, I had to start giving my bank and my cable company my carrier phone number for SMS security codes. Very annoying, because in the past they used my Google Voice number to text me with no problem.
So, even though under my current firmware (on my rooted Note 9) I cannot get carrier phone calls, I still have LTE data. And with the LTE data, I can use Google Voice (calls and texts) because it's VoIP. I also get AT&t carrier texts, as that is also data. It's just AT&T phone calls I cannot send or receive.
AT&T deactivated the SIM card in my native US998 V30+ and sent me a replacement phone, which is a Samsung Note 9. I'm staying with AT&T for a reason. Otherwise I would probably pull the "V30" Verizon trick also.
I bought both my wife and my elderly mother 64GB V35 phones -- which is basically an upgraded 64GB V30. (They previously had native US998 V30.) AT&T gives V35 VoLTE and WiFi calling, and for them there was nothing new to learn.

I think it was a hardware problem, honestly.
No matter what I did, I even tried different ROM to ensure I didn't mess around with root settings and somehow enabled or disabled something that I should not have. I tried flashing stock radios, and no, nothing would fix it.
I took my brothers phone to see if the SIM card would work with his phone, an unlocked Google FI phone. As soon as I installed the SIM, and booted up the phone, I could tell it was working perfectly even on the lock screen. Right away the status showed the name of the wireless company, and active 5G data icon on the status.
I must have damaged the internal radio or the LTE data modem when I dropped the phone last. The screen of the phone never broke even though I dropped the phone countless times, though the back glass has cracked lines all over even if the surface is still smooth and the phone continued being waterproof (I tested).
Anyway, I have since bought a new phone and the Data/Text/Talk all work perfectly on it.
I'm not sure what I'll do with this phone, as selling it wouldn't be ethical. And I doubt anyone would buy a phone with the warning that service may not work.
Ah well, I may just keep and use it as a test device.
Thanks to all who tried to help.
