According to Frequency check, the AT&T model H931 supports 1/1 GSM, 2/2 UMTS, and 4/5 LTE bands on T-mobile, here's the link https://www.frequencycheck.com/compatibility/oywYtD4/lg-h931-v30-td-lte-lg-joan/united-states

Yes that's what I saw also not I wanted to see if anyone had done it. I plan to unlock then and change carriers to T-Mobile.

I also want to know if VoLTE works....

Hey here's my thread.... I have an unlocked AT&T V30 on T-mobile. No VoLTE at this point, but I plan on trying to mess with the Build.Prop to see if I can get it working. I had to mess around to get the tethering working, and I have not had much luck making it persist after a reboot, but I found an app that makes editing a bit easier.
What else? Umm, oh yeah, updates.: I am still on the November security update and have not had a ton of luck getting the January one. I am worried about that happens when oreo drops - I am assuming I will have to get my hands on an AT&T sim at that point.
You know about band 71 already.
No wifi calling... but I do not use that anyway.

Yea Oreo already dropped. You can probably update via LG Bridge. I'm selling mine. I had two but sold one so far. I bought new TMobile variants.

Verizon G3 for T-Mobile What should I know?

Ok, I'm buying a G3 thats for Verizon but for my T-Mobile service. I want to flash roms etc and I'm coming from a unlocked T-Mobile Note 2. Anything I should know before I buy it? Is it fine with T-Mobile?
T-Mobile runs on GSM network and Verizon runs on CDMA so the two won't work.

I thought it was SIM unlocked and worked

Don't give false information if you have no idea what you're talking about? If this information were true, how am I using a Verizon G3 on ATT with LTE?
The Verizon G3 is unlocked so it will work on either T-Mobile and ATT. It picks up LTE and HSPA+ on both networks. But LTE depends on what frequency is used in your area.

Alright, you got it
LTE on band4 works fine on the vs985 on both T-Mobile and Cricket pre-paid. H+ gsm works as a fallback, too. Verizon phones have had GSM radios since at least the Droid3, if they were "World Phones", like ALL current LTE models are. Verizon used to require a code be entered before GSM would work, and even then no USA GSM networks would work. But that's all in the past.

Actually it will work. I'm using mine on T-Mobile now. 4g lte is limited since verizon g3 only supports one band thats compatible with tmobile. But hspa+ or regular 4g works, spa or 3g works edge gprs all of those work.

?SIM Unlocked Sprint S6 on T-Moile?

OK Question:
I have been trying to find reliable information on this specific question for quite some time.. I am wondering two things:
How well will a Sprint Samsung S6 work unlocked on T-Mobile? I was comparing Basebands or bands or whatever and it has most of the LTE bands but none of the 3G bands. Does that mean that IF I was in a place where LTE was not available that it wouldn't be able to connect to 3G? How well would this work?
Thanks

Ok Please give me more information. how well will it work? Perfectly all the time?
If you are in the United States, by law the carrier cannot "lock" a phone to be only activated by their own network. You may have to call them to get it unlocked though. They may request for you to pay off the ETF on it, which is usually the remaining balance of the discounted phone on contract.
So really there is no such thing as a locked phone anymore, at least not for now. The hardware on the Samsung S6 should be the same for all carriers, the only difference should be the SIM card.

[Q] H830 usage on Verizon - LTE/build.prop help

Hello all,
I am having some difficulties getting my LG-H830 working on Verizon. The phone is carrier unlocked, stock rooted and BL unlocked. I've gone through the hidden menu and when I set LTE band to 2 or 4, it says SUCCESS. I've activated the SIM on another phone before moving over to the G5 and it shows up on my account.
I get bars but no LTE symbol, so I can't make calls via VoLTE (voice over LTE) and I don't have data. When I had it working on T-Mobile, there was an LTE symbol so I know it has LTE modem. I'm wondering if I need to modify build.prop to work on bands 2,4?
FYI on the lockscreen top left it says searching. A bit odd since I have four bars.
Any ideas? Appreciate any feedback!
I'm out of a phone until its working.
EDIT/UPDATE:
I'm trying to find the proper build.prop settings to get LTE working. Currently I am looking at my VZW LG G3 build.prop, however I've yet to change any settings that gets the LTE icon showing up. I've replaced the apns-conf.xml file from the G3 in order to have the proper APN configuration.
Things I'm trying (for the most part):
ro.build.target_operator=TMO (as VZW I do not get any service, with TMO it says Verizon Wireless and I get bars, but no LTE)
ro.telephony.default_network=10 (was 9)
telephony.lteOnCdmaDevice=1 (was commented out)
ro.cdma.home.operator.numeric=311480 (didn't exist)
ro.cdma.home.operator.alpha=Verizon (didn't exist)
gsm.sim.operator.alpha=Verizon (didn't exist)
gsm.sim.operator.numeric=311480 (didn't exist)
gsm.operator.alpha=Verizon (didn't exist)
gsm.operator.numeric=311480 (didn't exist)
persist.radio.volte.dan_support=true (didn't exist)
ro.afwdata.LGfeatureset=VZWBASE (was TMUSBASE)
persist.lg.data.fd=0 (was -1)
ro.com.google.clientidbase.ms=android-verizon (was android-hms-tmobile-us)
ro.com.google.clientidbase.am=android-verizon (was android-tmobile-us)
ro.com.google.clientidbase.yt=android-verizon (was android-om-lge)
I can also go into the hidden menu. Attached is what shows after selecting LTE only for the RAT.
NOTE:
Band4 confirmed in my area
A gsm phone won't work on Verizon because they are a cdma carrier you can only use it on carriers who use att or T-Mobile towers because they use gsm networks.

The LG-H830 supports LTE bands 2 and 4. It also supports VoLTE (Voice over LTE) and so does Verizon. I don't believe yet that it isn't going to work.
Have you confirmed the correct apn has been setup in settings - mobile networks? These aren't always set up automatically, and if it isn't set up right, you will have a regular phone connection but no data connection.

Copied directly from my VZW LG G3 (4G). It is actually showing the radio as connected to 4G, just no 4G icon, data or calling.
Have you checked here: verizonwireless.com/bring-your-own-device/
According to T-Mobile site, your g5 doesn't support LTE band 13, wich is verizons main band..
Edit: This is a guide for adding bands

I'm aware that it doesn't support band 13, however in my area I've confirmed that band 4 is in production. My LG G3 is currently connected to band 4.
I've seen that thread before, I should probably add band 13. I don't think that is my issue at the moment though. It could be that Verizon requires a connection to CDMA before 4G use is allowed. I'm not entirely sure. Theoretically it should work..
This one is for the g4, might be more compatible with the g5. Maybe it's possible to unlock the cdma bands aswell.
Good luck and please report if you succeed

I tried to use my T-Mobile LG g5 on Sprint and it wouldn't work I asked both sprint and T-Mobile they both told me it wouldn't work because the network's were different. I would love to get band 17 working on mine so I can use that band on cricket because they have a cheap truly unlimited plan but I don't think it's possible is the only band the T-Mobile LG g5 doesn't have that att uses but if you or someone figures out how to do it would love to know about it!

band 17 is a "subset" of band 12. afaik.. the at&t g5 doesnt have B17 either.. just B12.
if you can get cricket month by month it might be worth testing it.. worst case you're out a months service price.

Yeah I'm gonna try it because I know it will work for the most part I may just not have 100% of the coverage for cricket but my parents have 4 lines on cricket so they have 1 extra line they aren't using so for the truly unlimited plan it would only be $30 for a month because the 5th line gets a $40 discount so definitely worth trying out like you said and T-Mobile has already unlocked my phone but I had to pay for one more month so I won't switch til August 3rd.

How did you do that?
Can you provide proof like with LTE Discovery screenshot?
If true, you're going to be a hero and cause a lot of excitement...
Even with root and "enabling" via T-Mobile network hidden menu, no one in the past few months could get LTE band 71 to actually be used on US998. We gave up.

@guytano86 should use Network Signal Guru since they state they are rooted. It should present the most accurate, and complete info.

Yes. See the WTF bootloader unlock and root thread.
https://forum.xda-developers.com/lg-v30/how-to/wtf-lg-v30-t3790500
So...have we cleared up the discrepancy about whether or not band 71 works on the us998 model?
---------- Post added at 03:49 PM ---------- Previous post was at 03:45 PM ----------
Also, anyone know the difference between models us998 and us998u? I'm looking to get a used one from eBay but it appears people use these model numbers synonymously. And us998 is the us Cellular version...and locked version as well? Huh?
(BTW my goal: I have TMobile and really want a rootable phone that will work on band 71 with wifi calling - are we there yet?)
Thanks everyone! Amazing community we have here!!

OnePlus 6 meets that requirement. Then next month the Pixel 3 will be out with B71 already confirmed and will be unlockable.
Maybe the Moto Z3 Play, E5 Play/Plus (only the versions sold by TMobile) can be bootloader unlocked but not sure.

Yeah, but he wants a premium phone.
Like with IP68 (or ANY IP rating), Qi wireless charging, QHD 1440P resolution.
OnePlus is a pretender, not a real premium phone.

@ChazzMatt I've seen your name pop up quite a bit about this band 71 functionality, but haven't read anywhere you personally ever got it to work. Yet in this thread 2 people claim they got it to work. Any updates? Have you ever gotten it to work or seen actual evidence others have? Thank you kindly!

I don't use T-mobile, I use AT&T so the T-mobile Band 71 wouldn't show with my SIM card. AT&T doesn't use Band 71 and I have no roaming on the AT&T Prepaid plan I use.
I do know we cannot flash T-mobile modem as I was hoping, due to the different RSA encryption LG/T-mobile mandated for the H932 (different from all the other North American variants, for some reason).
But yes, others say they have gotten Band 71 on rooted US998, with T-mobile SIM card using various tricks like the Shortcut Master Lite, etc. I have no way of confirming what they say.

Cell Signal: V20 vs V30 vs G7 ThinQ

I currently have a LG V20. Where I work is probably 3 miles from a Verizon tower. We have very weak signal out here, and sometimes I can't even get texts for a while.
Which of these 3 phones have the best cell reception?
Depends on the Verizon bands available in your area!
If Verizon have band 46/66 support in the area, V30/G7 will be better. Otherwise they are probably gonna be all the same.

Yes. OR if Verizon soon adds support for these bands where you live
And that's because the V20 can NOT receive those bands but V30/G7 can.
Like back when AT&T started adding LTE band 5 all over the country as a supplemental band, in addition to 2, 4, 17 (now called 12). You needed a newer phone or you never saw LTE band 5... Was used in areas of congestion.
Since this is the V30 forum, my vote is on the V30 of course.

If you keep it on while you drive, it will keep a record of all bands you lock onto.
You can also use it while standing still to see what band is near where you are, of course.
CDMA SHUTDOWN
Also be aware that in six months (December 31, 2019) Verizon is dropping 3G CDMA -- so all you will have is 4G LTE. To make phone calls you will need either LTE VoLTE or Wi-Fi calling.

Somehow the ZTE Axon 7 (not even a Verizon device) has Verizon VoLTE on Lineage. (Or did a couple years ago. Have not checked recently.) It was a mystery the dev either could not explain or did not want to explain, at that time.
