Hello, I am on AT&T on a GSM Galaxy Nexus. This problem has been happening since the the 4.2.1 update to JB and made me root and flash CM just to see if it would solve it (though I initially wanted to because I was curious since this is my first smart-phone).
So the problem is that at work and certain places I get absolutely no data. I can text sms (no mms since no data) and call people just fine but nothing that requires a data connection works since it timeouts. It happens specifically at work. Nobody that has AT&T in my office has problems except me, so I'm ruling that out. Now previous to this I would encounter the problem in very densely populated places like shopping malls or stadiums but I don't think that's the case here.
Here's the other strange kicker: if I switch to "GSM only" instead of "WCDMA Preferred", it works just fine but it's only Edge so it's slow. I have also tried "GSM/CDMA auto (PRL)" to no avail. The only one that works consistently is "GSM only". Once I leave work I have to switch it back again to either of those to to get HSPA+.
I have flashed multiple versions of CM to see if it fixes and since I like the rom so much I haven't gone back to stock. I've done CM10 Stable through M1~M3 and RC1~RC3 to CM10.1 stable and absolutely nothing has fixed it. It is driving me insane because sometimes work is slow and I grow stupidly bored.
Any clues?
Try flashing a Radio. You can find a list in the development forum.

Ok I'll look into it. Also noticed I have a ton of APNs...
Here's a list of what I have:
ATT wap.cingular
ATT Activation Iwaactivate
ATT Broadband broadband
ATT LTE pta

It is my first forum post and I believe I am posting it in the right section... I tried finding a similar problem to mine, but seemed to only find people that wanted to turn LTE off instead of on. The AT&T Galaxy S3 phone is rooted and I have gone between ics and jb roms and have gotten LTE to work every time. The problem is after I reboot the phone I lose LTE. I get 20+ up 10 down on LTE. After I loose LTE I get around 8 up 4 down.
I have tried.
1.) Re-installing a rom which gives me LTE until I reboot phone.
2.) I have tried installing modems from http://forum.xda-developers.com/showthread.php?t=1831898. If I have lost LTE after reboot, I can (9 out of 10) get LTE to work again after installing a modem. I lose it once I reboot the phone again though and am unable to flash a new modem to get LTE back to working and it won't unless I do 1.) again.
3.) I have made sure apn settings are on the correct pta lte setting. Usually most of the rom's have that already set to begin with.
4.) I have tried the *#2263# to change it to LTE. This WORKS and will reboot my phone into LTE everytime, but I lose being able to make phone calls, etc. From what I understand as well, I am unable to go to 3g/2g after settings LTE ALL and I don't want that either...
It is the only problem I have had with this phone. I notice a lot of times after I install a rom and reboot, it upgrades, and I lose LTE. I install a modem and get LTE back. I reboot phone normally without doing anything to the phone and it upgrades apps again and I lose LTE. That is the only conclusion I can come to as to why I lose LTE after reboot.

I am in the same boat as you. I can force LTE with *#*#4636#*#* and setting it to LTe only. But I lose phone calls and if I restart it goes back to WCDMA.
What rom are you using some roms don't have the late icon they have 4g instead. Also double check that you have the right lte apn enabled

Yea I realized that jb roms do not show 4g lte, they just show 4g. I check to see if I have LTE by doing going to the Settings->About Device-> Status and looking at Mobile network type... and/or a speed test as well.
I came from and tried these rom's

WanamLite Smooth,Stable & Battery
Right now I am on Stock TouchWiz Jelly Bean PORT (JellyBean 747 Milestone 3)
I have gotten LTE speeds on every single one of the roms until I reboot phone.
[Update- Best Solution So far]
I found that using the WanamLite Rom http://forum.xda-developers.com/showthread.php?t=1782732 enabled me to get LTE back fairly easy.
Everything is in the Settings->More Settings->Mobile Networks area.
1. I entered in a new Access point and just put Name: "pta" APN: "pta". You can fill out the rest like the MMSC, MMS proxy, etc but I did not need to.
2. Then went to Network Operators and waited for it to search for the networks (takes a minute or two). It showed up for me as two options being Maritime and AT&T. I selected Maritime and registered it. I was not able to register on AT&T and I don't even know what Maritime is. However,
3. I went to Network mode: Set it to GSM/HSPA/LTE(Auto mode). I get LTE every time.
Every time I reboot I can get LTE to work by doing steps 2.) and 3.) and is a little annoying, but better than having to flash a rom every time I reboot and lose LTE. I would like to try and find a solution though where I wouldn't have to do this every time I reboot.
[EDIT] There might be roaming charges, but by disabling Data roaming you should be fine. I believe you might incur charges if you try connecting to this network while on a cruise and have data roaming enabled. I have not done a lot of research on this so I could be wrong.
What radio do we use with Wind on the t989... I am in Burnaby Vancouver.. and I am told that Wind has away mode and home mode.... This is confusing as it determines what we pay.
Also when you flash a jellybean Rom it no longer sees the carrier as Wind Home and Wind Away with proper transitions instead I simply see Wind Mobile....
Also I want to really unlock good signal strength and if I am lucky better speeds but all I know to do is use UVLH5 and use *#*#4636#*#* and select CDMA/LTE which takes me to WCDMA preferred ... but most people say that I sound like I am in a tunnel if I am standing next to window... it isn't until I actually go outside that the phone actually works !!!!
Anyone else having problems ?

I'm not sure about your first issue with the away mode thing, however, I do know that if you go into dialer and press menu then go to settings and check noise suppression it makes things sound a lot better.
I don't live in Canada, but I'm guessing that Wind Home is for home internet, phone service, etc. Wind Away is just like any other carrier for mobile phone service. On JB ROMs if it says "Wind Mobile" that's fine. That's the name of the company. The reason you might not be getting good service is because the UVLH5 is meant for some certain phones on T-Mobile, the Blaze 4G especially. In order to get better service/signal/call quality, try flashing a radio meant for the T989D which is the Canadian variant of the T989. You can also enable noise suppression.

While oddly enough the carrier would switch from "Wind Home" to "Wind Away" prior to jellybean. I have tried the T989D modem but never get better reception. Does that make sense ? It always would go into radio off mode where you would have zero bars and no matter how many times I reset the phone the radio had no response... Weird...

I guess you should keep trying different radios and see when one starts to work. It could also be the ROM's fault.

| live in Richmond and am with Mobilicity. I am running Liquidsmooth with the Tmobile UVLH1 radio. I've tried other radios but find this one gives me the best reception. Mobilicity doesn't have an "away" mode but I do get the Roaming "R" when I am away from my coverage area. In this instance, I roam on the Rogers network.
I got a SGH-T989D from Telus with TLLE4 radio.
I am a Wind customer in Toronto and I can say that the signal changes. Depends on their cell system. Even if Wind states that it has full coverage in Toronto, I found that during some days I have only 1-2 bars of signal, Other days it goes full.
I assumed that they are still working on their infrastructure.
As others sugested, you can try other radio versions from http://forum.xda-developers.com/showthread.php?t=1895400
home vs away
WIND HOME = you are connected to the Wind 3G / HSDPA+ network and you have your regular wind rates ( most likely unlimited in your plan )
- wind mobile ONLY has a hsdpa network. no gsm!
WIND AWAY= you are roaming on the rogers network using 2G / EDGE and you are paying per minute roaming rates 20c/min for calls. Your data is $1 a MB i believe, but will only use data if you enable data roaming manually.
If you go to USA it will still just stay WIND AWAY while you are roaming on one of their carriers.
These names come from your sim card, not the phone or radios.
Anyone having problems just connecting to Wind? I'm on CM 10.1 (nightly build) and living in Hamilton... and I have a ridiculously hard time connecting to the network while everyone else I know on Wind (with different phones) can get on almost instantaneously.
I swear I've tried every single radio, and each has little or no difference. It takes literally 5 minutes for my phone to stop searching for networks (I have WCDMA preferred selected) and once I click "Wind Mobile" it takes at least another 30 seconds before it connects to that.
Anyone else experiencing this issue? It's driving me insane!

Unfortunately the same applies here as well (Ottawa) using CM10.1.
If you don't mind loosing signal outside the wind home zone the best settings for a prompt reconnect would be to set it to wcdma only combined with automatic network registration.

hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.
Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test
I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread

I flashed the Lollipop version of Liquid Smooth on my AT&T G3 and at first everything was working fine, 4G included. After a couple of days 4G disappeared. When this happened it didn't just go to 3G, it lost all data service completely. I originally figured it was the ROM and flashed back to the previous ROM I had using the TWRP backup I made beforehand. Same story, no data service. Figured maybe it was the modem so I flashed a working G3 modem on here, same story. I flashed to a different Lollipop ROM, Resurrection, to see if that fixed anything, nope. This is the ROM I currently have installed. At this point I went and look at the mobile network options and immediately noticed 1 issue, the preferred service was 3G and not LTE. I had an option to change it to LTE but when I actually select LTE it doesn't actually switch, it just stays on 3G.
The one good thing I managed to do was switch the APN to one that worked with 3G. The APN that was originally set was "pta", I can provide the actual APN information if that'll be useful but I figure most ROMs are going to have similarly named APNs. 3G works on at least 2 of the APNs listed for this ROM, "broadband" and "wap.cingular".
I called AT&T and determined that I my 4G service wasn't cut off; not that I really thought it was anyway as that wouldn't explain why I can't even select 4G as a network type. I'm kind of at a loss as to how I just randomly lost 4G access without actually making any changes to the firmware or OS of the phone. I'm also at a loss of how I can get it back.
And I am just sitting here with 3G with speed of 2 Mbps...
No one has any ideas or advice?
I just bought a T Mobile LG G3 (D851) for use on AT&T. The guy I bought it from got the unlock code from T Mobile and that is all squared away and unlocked. Things are basically working on AT&T, but data is not working reliably for me. It works fine for awhile, then it just stops working--the 4G/LTE logo in the status bar disappears and I have no connectivity. I can still make phone calls and send/receive SMS texts (though no MMS texts), and if a wifi network is around, that works too. Rebooting does not seem to correct it (though it does start working again eventually).
I don't know if it is just random, but it does seem to happen after I'm leaving somewhere with wifi (and that may not even be relevant--might be that's just when I notice it).
I have verified my APN settings (as well as tried other slightly different settings I've found around the web), but the data network still drops out. Yesterday, I discovered a technique that seems to reliably bring it back on after it has dropped out. If I change the Network Mode to anything else (ex: just GSM), then back out of the network options menu... then go back in and set Network Mode back to LTE (etc). Every time I have tried this, I get the 4G/LTE logo back in the status bar and my connectivity is back.
I know there is some difference in the LTE bands supported by AT&T and the T Mobile LG G3 (D851), but the phone supports band 17, which I'm told is the main LTE band used by AT&T. At this point, I think I'd be satisfied just to have consistent 4G (non-LTE) data.
Any idea what might be the issue? Or anything I can try out? I'm considering flashing a different rom to see if that helps, but wanted to exhaust other options first.
Thanks...
