Lg V30 No LTE, most of the time - LG V30 Questions & Answers

So my lg v30 will connect to LTE on extremely rare cases, any other time it will not. I've been monitoring signal and events through Network Guru. According to it my LTE has a problem attaching. Whatever it is that means. So when it does connect to LTE and I move out of range of one tower, I get Tracking Area Update Failure. What could be causing this? How can I fix it. I've set the APN to the best of my ability, but currently I get message APN settings not available for this user. I can still add an APN and save it, but I have no idea if it actually saves cause I can't view the list of APNs. However even before this APN message I had these problems and I knew for a fact the APN was correct. Any help is appreciated!

So you have H931 converted to US998 and then with Lineage custom ROM installed.
But you are limited to T-Mobile coverage.
Do you live in good T-Mobile area? For instance my mother doesn't. There's no T-Mobile towers near her.
If you are in a good T-Mobile area, you have two options:
1) Ask in Lineage custom ROM thread how to edit/create APN.
2) For test purposes, sign up for cheap T-Mobile MVNO like Mint to see if you get better "T-Mobile" LTE signal. You're only using T-Mobile anyway... First sign up and get "new" phone number just to get a Mint SIM card for test purposes. If you like it, then port your real phone number over and let the "test" phone account die (it's prepaid, so not much money).
Or any T-MOBILE MVNO which allows you to "Bring Your Own Phone".

I have tried many different carriers, all the same no LTE but gsm/edge works fine. Today I got to my jobs workshop and LTE started working, but as soon as I got into the town I was working in I lost it, LTE attach failure, or Tracking update failure. I'll see what I can do on the APN side of things. But do you have any information as to why it could get LTE sometimes and then other times the LTE attach failure comes up? At this point I'm likely just gonna get a fi compatible phone (Edit: one that has the auto network switching, the v30 is supported just will only work on T-Mobile towers), but just for learning's sake I'd love to figure this out. I looked at the coverage map for T-Mobile and I appear to be in a good area, and both the shop and the town mentioned above seem to be as well. Its almost as if the phone struggles to switch between towers. (I'm no service expert)

Is there a US carrier lock on the Photon's SIM card slot?

Can the Photon 4G be used on AT&T or T-Mobile after unlocking the SIM card slot?
As far as whether or not the GSM radio is locked... no it isn't.
However, the software for the GSM radio is written in such a way that makes the phone "ignore" US based GSM carrier networks.
The TouchPro2, the last Smartphone world phone offering from sprint had this same implementation. It required a custom radio written to get around it.
So you are saying a rooted phone can actually use an AT&T sim or T-Mobile sim?

Not really. Rooted just means you now have admin access to the phone basically, does nothing else.
What he is saying is that the software the controls the radio would have to be rewritten in order to accept US GSM networks.
Whats funny though, is that i went into a no CDMA coverage area 2 days ago, and I got a message on my Photon that asked if I wanted to use the available GSM networks. I allowed it and it roamed off of a GSM network...calls worked great, data was very slow.

You were in the US when you did this? If so what Sim card is in your phone? and do you have the phone roaming set to auto, because the default is any CDMA.

Yes, actually in the west Michigan area. The SIM card is the standard that came with the phone. It was set to automatic when I got it, never actually looked at the roaming settings until I got that message.

Odd, like reddragon72, mine came with roaming settings set to CDMA only.
Based on your experience, though, I've changed mine to automatic, thanks for the tip.

my pleasure, for me it just means im less likely to lose service or drop calls. which very useful. utilizing that feature greatly improves the coverage map.
I would check on this first. For one the roaming agreement that Sprint has is only with Verizon(CDMA). From what I gathered on Sprints website they do not mention who they are in agreement with on roaming in the US but CS told me Verizon is who I would be roaming on. So I would check your account for strange charges before you go crazy using GSM, but at any rate this is awesome info.

Im looking into this as we speak, i actually work for Sprint as a repair tech. So i forwarded the info up to our rep. who is going to check on all this before i end up with overages. i will keep you posted...
Sprint used to have roaming agreements with AT&T, Dobson, Cellular One, etc back in the days of "Analog Roaming". I wonder if something here might be a legacy from that.

This item will put a definite buy in for me on this phone. I work in a fringe cellular area (CDMA and GSM), but the office just installed a GSM repeater for Blackberrys and GSM phones. If I could freely roam on the repeater I would have this phone asap.

That sounds good, but remember if 50% of your calls are roaming three months in a row, or 50% out of 12 month average then they will cut your contract and cancel your account.
I put a working T-mobile SIM in my Photon today and it did not work. It appears that the unlocked status of the phone does not extend to US carriers. I would be interested to see how the included SIM behaves in Canada with Bell or Telus who are roaming partners for Sprint and have both CDMA EvDO Rev A and HSPA+ networks.

[Q] Is GSM unlocked on Verizon S4

I just killed my Nexus and I'm not eligible for a discount with Verizon until 8/22. I'm looking at the S4, full price in my case, I guess (sigh!) Does anyone know if the Verizon Samsung Galaxy S4 comes with GSM unlocked? (I remember reading that the Verizon iPhone 5 does and can be used abroad by simply swapping a local SIM card.)
During my trial purchase on the Verizon website, it asked me if I wanted to keep the current SIM number (yes), and later if I wanted the phone implemented for worldwide GSM (do you think they mean through their own services, hence locked GSM, or open to any carrier abroad)?
Thanks for the input.

All you have to do is give them a call and let em know you will be traveling abroad, they will adjust your plan accordingly. I dunno if the S4 is global capable though, hardware wise.... Make sure you call them before using it abroad, failure to do so will most likely result in a massive roaming bill....
If you look on the hardware specs, it says its a Global Ready phone on Verizon's website. It has GSM also. I think it is possbile to put in a att SIM and go. Don't hold me to it though

Yeah, I believe it's FCC required because of auction rules for the 700mhz band Verizon LTE is using.
That said, you may still need root to enable new APNs.

I appreciate if you show screenshot of APN setting. if possible also network screenshot.
For now all I know is you can get WorldWide plan from verizon and you basically will be paying to verizon but you will use that other carrier as an atena... Cool, but it's VERY EXPENSIVE. Calls internet everything. Is there a way to somewhat hack sgs 4 verizon to use it internationally without needing that stupid expensive plan.
The SiMs are very cheap and the phone plans are very cheap in Europe, sometimes it's even more profitable to buy an unlocked phone just to travel.
So, does anyone know yet how to hack it ? There was a way like that on SGS 3.
I upgraded on Verizon and then traveled to Europe on the same day. All was working well with Verizon in the US. I then put in a sim card I bought when I arrived, and it worked for calling as soon as it started (no changes required). The add apn setting was greyed out, but it worked anyway. I put in the appropriate apn settings and it now does mobile data, voice, and sms. I dont know about MMS, yet.
I did all this without root access, but I went ahead and did the root procedure this morning.
I have to go to another country in 2 weeks, and I may get a different sim. If so, I will update after that.
I do have a persistant warning in the status bar telling me I am using a non-Verizon sim, but no other ill effects.

Hey, thanks for info. Are you using Verizons World Data plan ? If not, when you come back to US is it possible that you will get a pretty large bill for using outside of US ? What type of internet are you recieving, 3g, HSPA or maybe Edge ? What countries have you tried this in yet ?
Also where did you get the phone, pre order or in store?
Thank you, I'm asking so many questions because I really wanted to get an upgrade but I will be flying to Europe for this whole summer and I thought it wouldnt worth it right now.
No, I am not using Verizon's plan (as far as I know). I have a local prepaid sim and phone number with prepaid data on a gsm network (T-Mobile) and so I do not receive calls on my US Verizon number - they go straight to Google voice answering service. I get a H+ symbol for data when I am in an area with good reception, and 3g elsewhere. So far, I have only tried it around Berlin.
I bought the phone in the store.

Used my VS985 while traveling (foreign sim) with no problems

This may be totally obvious and non informative to some and for that I apologize, but I'm putting it out there anyways.
I recently traveled around South Africa for a bit and was able to use my Verizon LG G3 VS985 rooted bumped running official CyanogenMod 11 latest nightlies (via cyandelta) with absolutely no problems. I put the Vodacom sim (South African cell company) in the phone and it worked perfectly. I was able to get HSPA, 3G, and EDGE without any problems and no modifications made to anything. The phone did all the work automatically.
Supposedly there was LTE available in some parts of the country, but I could never get it. I tried switching APNs, changing radio radio bands in the *#*#4636#*#* and still could not get it. I was tempted to try and unlock the other LTE bands (as seen in a thread that I'm too lazy to look up at the moment) but I decided to hold off until later.
I also put the Vodacom sim into my LG G2 that was running a stock rooted something and that worked perfectly too(still no LTE). Was weird using that again though after the G3. Made me really appreciate the bad ass-ness of the G3.
Anyways hope this was not a waste of post. Rock on G3
Always good to hear a firsthand account from a traveler.
It would be useful if you could post what you used for APN entries as well.

All the APNs were auto populated and I just experimented with a couple different ones. Vodacom.sa and vodacom.lte.sa were the two that I tried. Ended up just keeping it on the LTE one hoping that it would pick up LTE at some point. Both APNs gave me similar performance and service. I never had to mess with the actual APN settings or manually input anything.
That's great, but pretty strange since the vs985 requires a new APN setting to be manually entered in the USA each time I switch to either my T-mobile or AT&T sim.

No support from Sprint

Looked into Sprints Community Forum to see if they will support this device and it looks like they will not. I am getting this phone and it looks like I'll be leaving Spint.
Here is the thread to the forum. https://community.sprint.com/baw/message/1052157#1052157 Wanted to share in case anyone else is getting it in hopes that Sprint would support it.
Sprint generally tries to avoid factory unlocked phones so their bloatware stays in place.
Yep, Sprint has strict control over what is allowed access to their network. While the A7 has all the bands for Sprint usage, ZTE has said that they're working with Sprint (and Verizon) to get it approved for their networks.
I wouldn't bother too much with what Sprint_Jeffrey & co. said, they are probably in a similar position to the people within ZTE who claimed just days before the boot-loader unlock announcement that they would not be allowing unlocking of the boot-loader. Until an announcement is made by the Sprint people responsible for such things reps like Sprint_Jeffrey & co. are as much in the dark as the rest of us.
What I've heard about this phone and other unlocked phones with Verizon and Sprint support built into the hardware is.
From official channels you will get no support for the device and you can't go to the store and activate the phone.
But most of the time if you take an existing sim from your current phone and pop it in the new unlocked phone it will work just fine. It's worth a shot before leaving sprint if you like the existing service you have.
Unless you were already planning to leave for the greener pasture of GSM service, so many more device options available which is why i only consider GSM carriers myself.

So you are disagreeing with the, probably, 50 posts I've seen with Verizon working on the Axon 7? I'm getting mine delivered today and will be trying it out tonight. I'm expecting it to work.
Eh, you won't miss Sprint. You could probably go with a cheaper service like Cricket and have better coverage, anyway. Verizon is the only CDMA carrier worth using, but you pay out the bum for the pleasure.

I tried again with Verizon and it is a no go. I hope those of you who are stuck with Verizon can get things worked out. I suppose Verizon will start to play nice in due time. I, however, have moved on to AT&T pre-paid. Took about 10 minutes for them to get my Axon 7 working properly. There were other ZTE devices in the store also. At least one other cell phone and a couple of other items. So they are already familiar with ZTE and had no trouble getting things setup correctly. Bye-Bye Verizon!

Did you make sure to use the SIM1 slot instead of the SIM2/microSD slot? Only SIM1 is CDMA enabled.
I don't know why Sprint and Verizon are dicking around. Moto G4 and Google Nexus phones can run on their networks why not ZTE Avon?

I have RingPlus with a "free" ($15 initial top-up) 1400 plan. And it's great that you have 5 nice plans, but let's be honest, R+ isn't the same as it was last year. Plans like that don't come up much (if ever) anymore and when they do, the hoops make it a real PITA. I'll be surprised if R+ is even around in another year.
And in any case, it's still Sprint and Sprint's network is literally the worst you can use. It's great if you never travel and don't need service outside of cities, but "free" is the only case in which I would use their network. I use R+ with my Moto E as a streaming music player when I'm on the beach or out mowing or doing something else where the phone might get trashed.

Yes, all attempts were in SIM slot number 1 only. Constant roaming. On AT&T now and all is working great for less money. No brainer if you can do it.

Er, constant roaming is normal... it's one of the many bugs that the A7 has on Verizon right now. Just had to check "data when roaming" and you would have been good to go.

Sprint locks their RUIM/SIM cards to the MEID of the device. Verizon does not engage in this 'anti-consumer' practice.
So can I just put a Sprint Note 4 sim in the Axon 7 and it will work?
I switched from sprint to cricket when I bought the axon 7. Got a good deal for signing up for auto pay and the signal has been wayyy better (in Pittsburgh). I drive all around town for work and only ran into one (almost) dead spot.

No this almost surely won't work. Though it's hard to be 100% sure as Sprint is so finicky with their different SIM card types...my Sprint phone is an iPhone 6S so perhaps the SIM isn't as friendly to Android phones (which is ridiculous but Sprint really does differentiate Android vs. iOS SIMs, which I found out the hard way)...
But I tried anyway with my FreedomPop Sprint SIM...below are some pictures of what happened. The Axon 7 showed a signal and a 4G/LTE icon, but the internet connection didn't work (it just shows a constant upload indication) and there was no 1X signal either when I checked LTE Discovery. So it seems that Sprint is effectively blocking the Axon 7 (as it would any non-Sprint MEID'd phone I believe) from making a data connection or making calls/texts.
It's a shame...Verizon doesn't do this...my Verizon SIM works great in the Axon 7...this is purely a Sprint limitation it seems, which is funny as they're the most desperate of the four major carriers and yet make it nearly impossible to do business with them even though we have a perfectly viable Sprint phone in the Axon 7.
Sprint binds the imei, icc id and phone number to the account. Everything has to match or you get no service.
Sprint is dead, move to a different carrier.

UICC unlocked on other carriers.

So I finally unlocked my LG V30+ on sprint, (LS998)
I'm curious about anyone who has UICC unlocked the phone on a sprint network, then switched over to tmo, cricket, vz, simple mobile, metro or some other company:
-Did everything work ok, data and voice?
-Did you have any issues? if so what where they
-other than popping the sprint sim out and the other sim in, did you have to do anything else to get it to work, ie: new apn?
I ask because doing a Google search and landing on sprint forums it seems that some have switched to tmo and had issues..... Most common ones seem to be either they have data and no voice, or they have voice but no data.

Well I didn't uicc unlock but I did flash us998 kdz on my ls998 and it sim unlocked it fine. I was using it on T-Mobile.
Everything worked as intended, volte and calls over WiFi worked fine. No issues at all. The only thing this phone needs is proper Android 10 support. WiFi on Android 10 for the v30 is a hit and miss. There are fixes available but that was too much of a hassle for me personally. Went back to stock.

So I finally unlocked my LG V30+ on sprint, (LS998)
I'm curious about anyone who has UICC unlocked the phone on a sprint network, then switched over to tmo, cricket, vz, simple mobile, metro or some other company:
-Did everything work ok, data and voice?
-Did you have any issues? if so what where they
-other than popping the sprint sim out and the other sim in, did you have to do anything else to get it to work, ie: new apn?
I ask because doing a Google search and landing on sprint forums it seems that some have switched to tmo and had issues..... Most common ones seem to be either they have data and no voice, or they have voice but no data.

That's because the Sprint firmware does not have all the bands necessary for other carriers. It's still a Sprint phone. Whereas if you convert it to US998 it would be more compatible with other carriers. Like stated above, on T-Mobile you get VoLTE, Wi-Fi calling, etc. Or use the "US998" on AT&T. Once converted it takes on the bands/modems of the firmware you are converting to.
I know you've already carrier unlocked your phone, but the easiest, most common way to carrier unlock LS998 is to convert to Open Market US998 or some North American carrier unlocked firmware. Which also gives you the advantage of better LTE bands. See attached screenshots.
No one who is not a Sprint customer leaves LS998 on Sprint firmware. At least people who have access to information on XDA. See Frankenstein instructions.
Like the other said.... make it a US998 phone and you can go wherever you want. I had my converted US998, which I then converted to VS996. This was used on Verizon and now on TotalWireless with no issues. I'm thinking of going back to US998 since I don't have to have VZ stuff on it anymore.
Make the jump and you'll be happy. US998 is a great place to be (except on VZ, where VS996 makes sense).
Yeah, if I end up switching carriers, I'll be kdz flashing the us988.
I left a lengthy thread on going back to sprint via the ls988 and frankenstien way, but I was wondering since you have to be rooted and bl unlocked, the phone won't register correctly back on sprint if the bl is unlocked, so in that case what do you do?
If it's not possible to do, then it's pretty much once you leave sprint it's a done deal, no going back.
Here is the thread:
https://forum.xda-developers.com/lg-v30/how-to/simple-question-us988-to-lg988-t4096609
Read the thread. Believe ChazzMatt's statements, as he is the expert on this phone and process. In the very thread you quoted, he says:
"Lots of Sprint people who have temporarily converted to US998, unlocked bootoader, then flash back to Sprint firmware -- keeping TWRP and root. One of our main DEVs is a Sprint customer. So your worries are totally baseless.
Why do you think we have TWRP flashable zips Sprint firmware to flash back to, if the phone couldn't be used?"
Bottom line, you'll be fine. The trick is you need to be already activated on Sprint. Verizon does the same BS... they won't let you activate on a non-VZ phone just because they're idiots. There is no reason not to do this, as you certainly can work with these phones. As I (and many others) have proven time and time again. I'm guessing Sprint may do the same thing...

I just purchased a Lg V30 H932 64GB (T-Mobile + GSM Unlocked) off ebay a few days ago. I put my At&T sim in it and set my APN settings to AT&T's (NXTGENPHONE) which is what I had on my old phone (LG K20 Metro unlocked).
I can call, text, and get online but the mobile hotspot isn't working. It allows other devices to connect but says " NO INTERNET".
Its very frustrating because I rely on my hotspot to use my pc and other devices. Any help would be greatly appreciated.

Probably should have bought Open Market US998. Easily root and use hotspot.
Maybe if you root the T-Mobile H932 you can get hotspot working, but T-Mobile H932 is more difficult to root than the other variants. You also can NOT cross flash T-Mobile H932 to any other variant.

It is true that H932 is the most locked down V30 model, and not one to recommend, except for users who need LTE band 71 (which only this model supports).
BUT I had no problems using HotSpot with my H932 on Red Pocket GSMA (AT&T MVNO). I just set it up under Tethering and it worked no problem. Of course the APN has to be correct for it, and I cannot tell you what that should be for native AT&T.

I wish I had known more about this before I bought it. I just assumed everything would work right since it was unlocked and compatible with AT&T. I never had any issues with my Metro phone that was unlocked.
I've never rooted or flashed a LG phone before and am kinda worried about messing it up. I've used Odin with my S5 and flashed it but never rooted it. I thought setting the apn settings to what I had them as on my previous phone would work but it doesn't. I searched the network operators and it only showed "RAT : ATT " and " RAT : WCDMA".
network mode only listed these options:
Automatic LTE/3G/2G
Automatic 3G/2G
LTE/3G
2G Only
The network mode I was using (on previous phone) was GSM/WCDMA/LTE auto but I dont have that option now..
Thanks for the help!

I actually fixed it and it was quite simple..I went to my apn settings. I used the NXTGENPHONE settings except I added "dun", to the end of my apn type!

Good, makes sense. As much as I agree about the limitations of H932, inability to tether isn't one of them!

Glad you got it working. The reason I suggested root is because there are some carriers who won't let you have hotspot without paying extra for the privilege of using your own phone to its full extent. Rooting solves that.

Fair enough: Adding "dun" to the APN only works when tethering is permitted by the carrier -- and it allows the carrier to meter the tethered data, and throttle it if they want. Personally I haven't had a traditional carrier in years, and the MVNO I use isn't the shenanigans type.
But do we really need root to work around that? I recall an old all trick from my Nexus 5 days where we would set tether_dun_required=0 in the global settings database using ADB, with no root required. I haven't had to do this on V30, again because I have avoided those carriers. But I would guess it still works.
I am asking, since surely you would know

Verizon is a carrier who won't allow you to "tether" without paying a separate hotspot fee per month. For those people still on legacy (true) unlimited data, many use root to get around that.
https://www.verizonwireless.com/support/mobile-hotspot-faqs/
Note: The $75 Prepaid Unlimited* plan also includes Mobile Hotspot with speeds up to 600 kbps. Mobile Hotspot isn't available on the $70 Prepaid Unlimited and $80 Prepaid Unlimited* plans.
If you don't have one of the plans listed above, you may be able to add Mobile Hotspot to your line. You'll be charged monthly to have the Mobile Hotspot feature, in addition to data usage charges.

Absolutely. We know that the traditional carriers like to limit or throttle tethering. I think T-Mobile does too. The dun feature exists to help them control that, by classifying tethered data separately from other data.
What I meant was do we really need root to work around that on V30? Doesn't the old trick I mentioned (or maybe a newer one) work on V30?
Edit: I may actually test that to find out. Dun in the APN shouldn't be needed in 2020.

I wasn't aware of any trick other than rooting because I've always had rooted phones...
In all my years of Androids I've really only needed hotspot one time -- when I was in Brazil. But I was rooted and it worked great.
Yes, I've tested a couple of other times, but again I'm rooted.
