No data on AT&T network - T-Mobile LG G4

Hello everybody,
Since I didn't find straight answer searching this forum I decided to create a new tread.
I have sim unlocked T-mobile LG G4 H811 that I'd like to use in with AT&T. Calls works fine but I don't have any data connection whatsoever. I can see several AT&T networks when I go to Network Operators setting but I'm unable to connect to any of them
So I was wondering if there's a special trick to make it work?
Thanks in advance

I found that going into the cellular network settings and picking 2G then wait for 5seconds and click LTE (recommended) again works. Not sure why this is needed but you would have to do this after every power off of the phone. Very strange hopefully someone gets to the bottom of this issue soon.

[Q] HTC First on t-mobile data issue

I just received my HTC First - new, unlocked. Wifi works. Voice works well. Text works well.
However, I can't get any t-mobile data at all. Can't get on google.com.
I have seen a few thread on rooting. Will root the phone solve the data issue?
Could someone please give me some pointers? Really appreciate it.
You need to add the t mobile apn manually in the settings
Thank you - adding APN worked :victory: I can get 4G now… Just not LTE

I believe that T-Mobile uses different LTE bands than AT&T, so you aren't able to use the First on T-Mobile's LTE service. Either that or T-Mobile LTE isn't available where you are.

AT&T Internet Settings for T-mobile Sony Xperia Z3

Hello everyone,
I have a T-mobile Z3 that is currently unlocked to work for my AT&T provider. I am able to make calls and send regular text messages with no problems. My problem is that I am only able to access the Internet via WiFi only and not 4G or even 3G. I am usually always around WiFi but for times when I am in need to use the mobile web, I am unable to. What are the proper settings for this? I understand that the T-mobile version does not share the same LTE band as AT&T so that's ok with me but 4G or 3G is ok with me. I have tried to APN settings provided by AT&T but it does not work. I am leaving on a trip in a few days and would like to have this working before I leave. I am sure someone out there has the answers I seek. I hope that I have posted this in the correct forum. If not, please feel free to move it as it might help me to get my question answered. Thanks again for your help everyone!
After doing more further research, I found the settings that work for my phone. I was just about to sell this phone and get a Note 4. Not anymore now that I got this to work. Thanks again everyone!

How did you get this to work? Help?
The phone was only on a temporary unlock and I am unable to use it for cellular service anymore but I went to this website to get all the settings to make it work for AT&T.

Sim Unlock for International use[SPRINT G4]

My friend is bringing me an Sprint LG G4 from the states. Was trying to find information but was not sure if the phone is unlocked for International use? Specifically Kuwait and India. I know we cannot edit APN's at the moment but can we use call and texting?
If it not unlocked, then is http://www.unlockallcellular.com/united-states-sprint-lg-g4-unlock-code-np-202435.htmlthe way to go?
Thank you
you can edit APN via ##3282#, you will need your MSL -search this forum you will find how to get it. But you will not be able to unlock Sprint variant for international GSM use. Only Sprint can do over the air and the phone has to be active on Sprint account for this.

Any chance unlock it now? Maybe flash or edit build.prop I don't know.
If you guys don't mind flashing/restoring your phone using the TOT method. You can try it out. I tried it out and it was SIM unlock out of the box. To edit the APN, I used Shortcut Master (Lite).
I'm from the Philippines by the way. The LTE bands of this phone doesn't support my carrier's LTE bands so no LTE for me.

Hi,
I just sent a Sprint LG G4 to my family in the Philippines and it receives Smart SIM card. But they just noticed that it doesn't receive any calls. I can make calls and send and receive text messages. Any inputs on this issue?
Your help is highly appreciated.
Thanks...

I'm not sure, is this on stock firmware? Can you clarify, so you can make calls, send/receive message(SMS), but not receive any calls while in the Philippines?

Thanks for your reply.
I am not sure if it's on stock, paid one cellphone shop here in california to have it gsm unlock. My sister who is currently using it in the philippines said that she just noticed that she cant receive any calls with it. In fact they tried calling it with another phone and it doesn't ring and even not give any notification for a missed call. The calling phone hears that its supposed to be ringing and after sometime it would say cannot be reached.
It can receive and send sms messages.
Again, thanks...

I'm not sure if Smart Network can access LTE but can you check? If LTE is available, can you make sure that the network selection is not set to LTE only, since sometimes it can affect making/receiving phone calls.

It has LTE/CDMA setting but if chosen wont get a signal. They tried the other two setting (Global and GSM/UMTS) but gives same result.

Try installing Shortcut Master (Lite) and try RAT_Selection(I'm not sure if it requires root though), then force WCDMA only if it will make a difference.
Just bought a LS991 that was supposed to be unlocked. Can it work on T-Mobile?
Hey everybody...
I bought a sim unlocked G4 from ebay. The seller claimed that it was unlocked for use with all gsm carriers, including t-mobile. After receiving the phone, I discovered that the phone was LS991 (Sprint version) and not the international version. If the phone is indeed unlocked as the seller stated, can I just insert a T-Mobile sim and start using right away? Or, will there be limits on the ability to make calls or connect to HSPA or LTE data?
Will the "APN" need updating to work with smoothly with T-Mobile? If anyone has prior experience in using LS991 on T-Mobile, please let me know!

Unfortunately, there is no way to rollback to older versions from ZVB.
For data to get working, you will probably need root access to reset the APN from APN settings. Sadly no root yet for MM, i believe.
See if you can access IotHiddenMenuMain in any way. It usually doesnt require root. If success, go to APN settings and reset to default APN.
Start with the shortcut master app.
Best of luck.

Its normal if you're out of USA, the ZVB update screwup all unlocked sprint LG G4 phones. The only solution is flash this:
http://forum.xda-developers.com/sprint-g4/development/rom-mellowmallow-debloated-60fps-camera-t3358340
After you flash Mellowmallow rom, you have to do a factory reset to acceso a gsm network, use the global version.
How Can I Flash it as above "evilboygenius" Said that I can't root my g4 or ZVB? Can you please guide the process or refer to any thread where it is explained?
Many Thanks

I have purchased the same sprint LG G4 (LS991ZVB) and updated it to latest Marshmallow 6.0 including other mini security updates too. I was having the same problem. After selecting the LTE or CDMA losing the signal.
Here is the solution:
1. If you lost the signal after pressing the LTE/CDMA or CDMA
Go to settings>General>Backup&reset>Network setting reset.
you will have your signal back
2. You can use 3G internet services of any network. just need to fill the APN setting manually.
Go to settings>Network>Mobile data>Mobile Networks>Access point Name
Now add APN (only interent settings. ignore the mms or gprs settings)
Here is the link of all Pakistani networks APN settings.
As i am a new user. I am not allowed to give outside link. However I have sent you link for APN & my contact number in private message.
Now you can use 3G internet. :good:

[Moto G] Can not access AT&T cellular network with CM13

Hi All,
I have a Moto G 2014 (titan) and have been using CM for a while. Last month I just moved to USA and joined T-mobile. It was good but expensive. So I switched to a family plan of AT&T last week. However, I can text and call, but could not access internet through AT&T cellular network. Custom services only tried to change SIM card and change APN settings (we tried a lot of APN settings). But none of them works. (Of course it works when you put the SIM card in another phone). So after googling for a while I guess the problem is with the "modem" firmware? I am not sure though, 'cause I am able to set APN. I hope you guys can direct me to the right direction. I was using a version of CM13 last month when I am with T-mobile. It worked fine. I did not do any updates when I switched to AT&T. However I just updated to cm-13.0-20160906-NIGHTLY. The problem persists. BTW it now just shown the signal but no sign of 3G, however, I do not remember if it is suppose to shown that. Does that mean I am not connecting to the 3G network at all?
It would also be real helpful if you can direct me to learning resources of cellular networks and how to troubleshoot such problem. For example, I found myself have no clue of the answer to the following question (excuse me if they are silly questions) and could not find an answer by google,
Is the APN settings related to the type of hardware of firmware that I am using? Does a specific hardware/firmware works in one APN but not another?
Thanks a lot!
Hey guys! I solved the problem by just erase modemst1&2 without install new modem firmware. Could anyone tell me why?
