Hey everyone I'm using the AT&T gs3 with task650's version of AOKP flashed onto it and it is the latest build. So anyway here's my problem, I live in Long Island NY and I often travel to Manhattan. Whenever I go to Manhattan or anywhere around there my phone doesn't get data but I see that i have 5 bars of connection and the wifi also works when I visit my friends house. I know that the areas I go definitely are getting good data connection because it is in the heart of the city. If anyone knows a fix for this I would greatly appreciate it, And sorry if someone posted a fix to this already but I couldn't find one myself. Thanks.
Hold your data toggle and in the settings menu that pops up, enable data roaming and reboot. If ghat doesn't work enable all networks in the data roaming menu and reboot again.

I had a similar issue recently. My problem was I went from 3g to 4g but forgot to select the correct APN. Make sure under settings>More>Mobile Networks>Access Point Names that LTE is selected. That solved the issue for me.

Background:
Ever since I've had this phone I couldn't get a data signal while roaming in areas where I knew one was available. Old phones would get data while roaming without a problem.
The Epic Touch would just give a notification saying "you have lost data connectivity" or something.
I understand certain Sprint roaming areas just plain don't have data available. This howto can not fix that.
What this howto does help you do is get a data signal while roaming in areas where a roaming data signal is available.
Credit:
This was apparently discovered by someone on the sprint forums, and I found a reference to it on the Android Central forums, so I do not know who credit goes to for discovering this.
What to Do:
It's best if you are in a roaming-only area to test this, or if you can force roaming. You'll also need to be on the stock kernel (rooted is fine) so you have the ability to update your Profile.
Let's do that now. Go to the Settings menu and tap About Phone - system updates - update profile and wait for it to complete, then tap ok.
From the home screen, tap Menu - Settings - Wireless and Networks - Roaming - Roaming Settings.
Un-check all options here (voice and data for both domestic and international)
With no boxes checked, tap the "Data" box under domestic roaming. Tap only this one, not voice.
You will get a box asking you to confirm. Click yes. This will then automatically enable voice as well.
Another pop up with a red box will ask if you really want to use data while roaming. At this point you can tell it to never ask again and click Roam.
Now you can use data while roaming where it's available!
Update:
after trying this multiple times to verify it works, occasionally the final pop-up with the red box disappears before you can read it. I was able to long press the home button to show recent apps, then tap the "Data Roaming Guard" app. Then I could tap Roam.
This is critical for me as sometimes I am in roaming areas for work and I need internet and this phone is the only access I have. Now I can use it!
Report back with any corrections or feedback. Mileage may vary.
I don't know if it's necessary to update the profile. I have that step in there because that is the sequence I used. If you try it without updating the profile, let me know. This would allow people on a custom kernel to do this too.
I spent an hour and a half with Sprint yesterday on the phone trying to resolve this. They turned me over to new reps three times (including to the international support department) each one not aware of my issue so I'd have to explain everything again.
Finally I started digging on the web and found the tip on AC. Took me 2 minutes.
DOH! Stupid Tapatalk.
Mods, please move to General. Didn't mean to start this in development.
Thanks for sharing this. I will try this out.

I have the same issues. My girlfriend has an EVO and she will have data while roaming, and I wont. Even if were right next to each other.
Thanks, this worked great for me & did not have to update profile. I am on stock rooted deodexed rom.
Worked for me! Thanks, that was very annoying!
thanks! now i can play wwf at work lol
I did this awhile back when I saw it on the AC forums. I also read this phone cannot roam on PCS networks because of a limitation in the radio so there still may be times it won't roam when other phones will.
Greetings All!
I was able to make roaming calls before; but I followed these instructions and now I can use roaming data as well. Fortunately Atlanta is a pretty good 4G metro area so I rarely need to use roaming data. Usually either 3G or 4G is available. Nonetheless it's nice to have the option.
FYI I forced roaming by using the Roam Control app and have verified that for the first time with this phone I have a nonzero "Sprint 3G Data Roaming" entry in the detailed usage screen on the Sprint website.
Many thanks!
Cheers, Henri
Ok, glad this is working for people! I know it was the biggest gripe I had about the phone by far.

Agreed. And such a simple solution. Thanks again.
I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

Re: Fixed service droping and locked LTE
To check if it worked. Go into test mode and it should say Lte in network type.

So does this mean we get no 3g?
Sent from my Mind using Telekinesis!
Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

O wow lucky u I can't unselect on Att lol
Sent from my Mind using Telekinesis!
Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

Ok sounds promising but unable to get my ATT phone running ROM cyanogenmod10.1 03/04 nightly into Test Mode using the keypad code provided. This does work for stock ROM phones. Do you know any other way to get into the test mode?
Haven't tried stock. Im on cm10..

I'm on CM10.1 not stock.

Yeah I'm pretty sure everyone is using cm10 or aokp. Not sure if stock is having these problems. If they were I'd be on the phone yelling at Telus.
Xda I747
So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Yes for me and others didn't even get 4g, also it would completely go out of service. Now I get steady 4g.
Xda I747
Any alternative way to get into "test mode" other than using the keypad?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Sorry man, I tried looking around for a way. Could be the rom you're on. I know Liquid and Carbon are fine. Probably a couple more that I don't even know of, others have success with.

stock lies to and shows 4G all the time, cm10 and show the truth. the s3 sets at 3g until data is needed then transfers to 4g
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 have noticed that there are people starting to notice that that have LTE in their frequenting areas, but it's messing with their data once they leave these areas.
For me it was having issues kicking back to edge and even 4G signals would not pull any data, would simply say that I had no connection. Didn't matter whether rooted or not or which rom I was using.
Anyway,
I have discovered somewhat a fix for this issue.
Under Connections tab in Settings, click more networks, then mobile networks, then Access Point Names my Access Point Name was epc.tmobile.com.
I noticed in other forums their APN should be fast.t-mobile.com so I thought I'd give it a try and incredibly my results were pretty good. It goes in and out of LTE areas pretty smoothly in comparison to losing data altogether.
Give it a try and report back.
Thanks
I was experiencing drop of data connection for long period of time (at least 5-10 mins) every time I leave the house, losing my wifi connection. More than once it just won't connect at all for a good couple of hours. I just did a test today, messing with the APN, network operator settings and get it to connect to 4gLTE. Once and turn on and then off the wifi, I lose the data again. And it wasn't gonna come back.
The fast.t-mobile.com address seems to do the trick and I'm now immediately on 4gLTE after losing wifi. and the speed is AMAZING at 24,000kbps download and over 10,000kbps upload.
Thanks!!!
I already had that APN setting but I wasn't getting ant 4G LTE :/ must not be in my area yet. I'm in north Georgia

With thr default (epc..) APN, I had LTE before in NYC, DC, Boston. It just happened that the connection drop was getting more and more noticeable so I had to do something about it.

great find, I must have switched between 5-7 different roms trying to figure out why I'd lose data for up to 20min. after coming off wifi. Once I got reconnected to 4g I was afraid to even turn my wifi back on.
This seems to me to have just started recently, I'll have 4G but I might use the elevator at work and lose my connection, upon being back in service I'll be stuck on Edge for about 10-20 minutes before it picks up the 4G connection again.
I've been switching to Airplane Mode then back and that seemed to help but it doesn't any longer.
My APN is already fast.t-mobile.com, is there any other solution to fixing this?
EDIT: If I reboot my phone it connects to 4G immediately, and I'm using a Rooted Stock MDL Build w/ the Faux kernel.
Thank you!

Unfortunately I do not know of any other things that might help with LTE connection. I just stumbled on this and thought I'd share what worked for me.
Can anyone with fast.tmo take screenshots of their settings for that apn. My Rom doesn't have that and I would like to manually add it in. Thanks!

Hello I live in Miami Florida I just came from a note 2 and prior to that I had an s3.. Both phones while on the HSPA plus APN did very well with speeds. The s4 does pretty well with speeds but I do notice that the data will get stuck sometimes and you see the arrows working as if they are transferring data but in reality its stuck most of the time I have to turn on airplane mode and then turn it off to get my data working again. This happens on any ROM and I never had this problem before this phone. I know that they are working on towers but even on the HSPA plus APN I'm having issues which I never have many issues on this network with other phones. Even on the LTE APN I noticed that a lot of times when switching from LTE to 4G I get so call drops or I get the internet stuck and have to turn on airplane mode even togglingmobile data on and off doesn't help.. Has anyone else experienced this problem I'm wondering if we were going back to the first modem on the first firmware will maybe help? Or is it just them working on the towers? If anyone has a good solution to this please let me know

If you can live without LTE for now, go into Settings -> Connections -> More networks -> Mobile networks -> Network Mode -> select GSM/WCMDA (auto connect)
I've had issues around here where the modem REALLLLY wants to grab LTE, but can't, and gets kind of stuck. But, HSPA+ is also pretty solid around here.
