Please help - 4G issues - AT&T S3 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So I am now on my second replacement phone. With the first phone my proximity sensor and brightness sensor wasn't working, now I believe I may have radio issues.
I have been searching and have seen mostly wifi issues but no 4G issues. I'm experiencing both and nothing here seems to help.
With my 4G ( LTE here yet) it will say it's connected with 3 or 4 bars but will not pull or push data. The 4G icon gets to work but the browser sends back an error saying that it's not connected when I of course have decent service and can still text and call. Of course turning wifi on fixes the issues but then the wifi continues to disconnect and reconnect etc.
It does this on stock, and the insomnia rom.
I've tried flashing the different official radios also with no luck.
I've dealt with different tiers of AT&T technical support twice for the replacement and current, they said my imei number was incorrect (for both) and a few settings since I ported from T-Mobile (They even entered my phone number wrong during the porting at AT&T), the AT&T guy did a few things over the phone and it sped up my data which was incredibly slow at first but still had the random connected no push pull data issue which requires me to restart my phone or when that doesn't work a battery pull. This happens multiple times throughout the day.
Also no service outages in my area as said by AT&T They will call me back tomorrow to waste another 3 hours of my day with worthless troubleshooting.
Should I go back to AT&T label this as another DoA and try another S3 device?
Is there a simple fix?
Could someone point me in the right direction please!
I'm still in my 30 day return period and if the quality of experience doesn't improve for me with AT&T I would like to just get the T-Mobile version, I don't have much time left though so please help!
Thanks,
Mars

Seems to be data issues that involve flashing ROMs.
Did lte work before you flash and rooted the gs3

Well I flashed my a rom on to my S3 for the first time today to see if it would help but it seemed to make things worse and when I did get data to finally work it was very slow So i switched back to stock. This was even happening a bit before I rooted

just received my replacement and the phone is functioning correctly. They gave me a new sim card also. The phone is noticeably faster data as well basic usage. Will report back. Not sure if it was the phone or my SIM though

I had the same issue.. I could talk and text but no data. I called customer service and the guy noticed I didn't use the lte SIM that came with the phone. Apparently you MUST use the lte SIM! Hope this helps!

did you have no data? or would you have random hang ups.. like it shows that you have 4G but it doesn't push or pull data?

Have you tried APN settings
Have you tried adjusting your APN settings? It can be an issue more so when flashing ROMS. I had that issue as well when I first got my phone.... Most of the time they will set by default but sometimes...not nav to settings>more settings>mobile networks>access point names and set it with these settings
Name: AT&T PTA
APN: pta
MMSC: h*t*t*p://mmsc.mobile.att.net***
MMS proxy: ***proxy.mobile.att.net***
MMS port: 80
MCC: 310
MNC: 410
APN type: internet+mms
Take out the *** under MMSC and MMS, Im new to posting and they wont let me post what they think is an outside link, leave everything else as is/blank and see if that helps.
Also if your not on stock rom try fixing premissions in CWM

on APN type: I've got this: default,supl,mms . I don't have 'internet'. I've also seen 'hipri' in APN settings before, on my older devices I had rooted and flashed (running stock ATM, just got the phone a couple days ago and trying to see how much I actually used root).

Default,supl,mms is actually fine... that should be a working APN I just saw someone had internet+mms and could not change it so wanted to make sure. When you rooted did you flash a recovery like CWM?

[Q] MMS issue

I just got the Lumia 900, and everything is working fine except I cannot send/receive MMS. I am currently on the newest update, but my APN settings were not built into the phone like they should have been. I manually inputed them and the data is working fine now, but pictures still will not send. Am I the only one with this problem? If not, has anyone figured out a fix? I called both Nokia and At&t. At&t told me the issue was that I didn't have a data plan, which I do, and Nokia told me to have At&t send an APN update push to my phone. At&t said they couldn't do that. Anyway, let me know if you all know of anything that could help.
Thanks in advance.
UPDATE: After spending 2 hours on the phone with AT&T and Nokia, I finally got tired and called an AT&T rep that I know. She took a look at my account and realized that I had data on my account, but it was never set up with the 4G data which is why I could access the internet via HSPA or HSPA+ but couldn't get MMS. The phone was just confused. She made the change for me and it's working fine now. If you're on AT&T, just call 611 and make sure you're on an LTE plan, not just a 4G plan and see if that fixes your problem.

Something seems wonky here.
You have a Lumia 900 on AT&T with a qualifying DATA plan, and you can't get MMS.
A couple of thoughts:
What aren't you saying? Hacked? Rooted, Unlocked??? Bought it off of eBay?
Have you tried a Hard Reset with the sim in? During setup, the first indication of a setup problem is, Time Zone, Region, Time are not setup automatically. Does this happen?
Do you have an official mini sim, or is this a cut down one? Cut down ones...might not work.
Take it back to the place you bought it....do a hard reset in front of them. Does it work? By work I mean does it detect time zone, time, your number. NO, its not usual for them not to...don't believe that if they tell you that. If there is NO detection....something is wrong..either with the Sim or the account.
Have them check your account...right there...is it setup? You should NOT have to input an apn on this phone, if all of the above is correct.
I have had 2 lumia's and a Samsung Focus S since March 2nd. Each one had to have the account reset. For some reason something went wonky on the phone during setup. Dropped vm, one time it was data plan not initializing. A Quick check caught them...

I am in the same boat. Bone stock 900.
Looks like an issue with 4G. When I change my data connection to 3G MMS works as expected, change it back to 4G, no workie...
I was going to mess around with APN to see if I can get one set up that works. There is a Nokia Network Setting app that can help with this but it's not on the Market Place anymore. I've been doing some searching and this appears to occur on many different carriers with 4G. I'm in the US on ATnT, but it is happening overseas too.

Might have figured mine out, I added an APN
apn: wap.cingular
user: [email protected] (all caps)
pass: CINGULAR1 (all caps)
proxy: 66.209.11.32
port: 8080
There is not slot for MMS so I skipped that, it would be:
mmsc: http://mmsc.cingular.com
Go to settings
Cellular
Edit APN
Input the above
Save (check mark)
I then toggled in airplane mode for 30 secs and then out of it. Sent my self a MMS and it worked, sent one from my wife's phone and it worked. Both of those scenarios were failing on 4G before. PITA
That app is off the marketplace

glad you got it to work. Are you in an LTE area?? I still maintain that having to input that apn indicates something is not correct. But, also realize you gotta get the phone working

Yes it work but..... It seemed to have reduced my data download speeds. So I deleted the APN and that got my LTE speed back.
Will toggle to 3g when an MMS fails for me. Will also start to bug ATnT about this too.

I'm more convinced than ever tht LTE may not be our friend. Nokia may be finished with the beta test, but AT&T isn't...or any other carrier that is
Can send MMS via LTE with my L900. No connection problems since I got it before launch day. Do you have a properly provisioned micro-sim.

Can't receive MMS from T-Mobile users.

When I get MMS from T-Mo users it shows up, but when I go to look at it the message is blank. Has happened from many T-Mo users but no other carrier.
Anyone have ideas?
I tried different roms, messaging apps, broadbands and apn settings, no work.
If you have ideas keep them coming even if I don't test....will test tomorrow....don't want to keep bothering ppl all night.

Who's your carrier, AT&T? My friend is experiencing the same issue. At least, I think it's the same. I'm on T-Mo and he never gets my MMS.
I tried putting the different APNs in his phone as well. I'm honestly not sure, either.
Wife and I are on tmo and I can't get any of the dumb ass mms that she sends me.
I take it as a blessing really.

The T-Mo users I know can send them but it just comes in as a blank 1KB MMS.....
No one has any idea here.....or can we at least get people to confirm they CAN get MMS from T-Mo users...
Mine does this sometimes. Im on sprint
Im pretty sure this is a gnex issue between tmobile and ATT, Switching my sim into a tmobile branded phone and it will send. Seems that all other providers receive my MMS though. I can receive an MMS from a Gnex on ATT to my Gnex on Tmobile. Im thinking its something to do with the user string of the Gnex and tmobile not knowing what it is.
I can send MMS to any one except people on AT&T. My best friend has an Xperia Play 4G on AT&T and my pictures just shows up as a white box. I'm using T-Mobile

I started having an mms issue on T-Mo recently. Fixed it by resetting the apn settings (the only thing that seemed to change was the ipv6 changed back to ipv4 - i believe you are supposed to have separate apns for data and mms)
Pull up the apn list, hit menu, then reset to default...
No one has any ideas about this ? I'm pretty pissed off now because I called AT&T and they basically said since it non-AT&T your screwed.......
and can we please get an AT&T user to confirm receiving MMS from T-Mo using this phone?
Not using a G.Nexus, using an HTC Sensation with a CM9 variant. Just noticed that I'm only having trouble receiving MMS from TMO friends. I'll keep an eye on this thread to see if anyone has a fix
I should probably clarify that I do receive the message if there's text in it, my phone recognizes it as an MMS but there is no picture and the size is 1kb.
It's definitely the IPv6. I switch it on and MMSs won't come or go. I switch back to IPv4 (and reboot..grrrr) and MMSs send/receive fine. I have checked and cannot find anything in the APN settings that's supposed to fix it.
You have to set up two APNs on the T-Mo phone:
Ipv6 for data
Ipv4 for MMS
I'm in the same situation. I'm using GNex on AT&T. My friend has GNex on T-Mobile. I can receive text but no picture messages from him or anyone that has T-Mobile. Let's keep this thread going to find a solution.
Sent from my Galaxy Nexus using Tapatalk 2
I've given you the solution.
The guy with the T-Mo phone needs to tweak his settings...
even tried to change the apn. I have a Skyrocket on AT&T my brothers and girlfriend have T-mobile and they send me MMS but nothing comes through.
I know other people that have AT&T and they have I-phone and get all MMS messages from T-mobile.

Phone won't connect to mobile data after flashing

After flashing my phone it can't connect to the mobile data network. I re-flashed the phone back to stock and it still doesn't work. On wi-fi the phone works fine. The 4g symbol shows up with the upload download arrows flashing but I don't get any signal.
Can someone please help me? I'm really frustrated...
Flash a different modem?
Did you check maybe you lost the imei on the process of flashing
If 4g is displsyed its probably not imei, but check it anyway.
Also turn off wifi calling and see if thst hss any affect.

You'll be amazed at what a battery pull can fix.
I've tried multiple roms with different radios/modems but no luck.
The IMEI is still there. I don't know what the problem is... For example though, every time I try to go to a website, it gets automatically redirected to http://androidapi.t-mobile.com/apppack/mvno.html I doubt that means anything but just putting everything that I know.
I have the same issue and cant figure it out. Ill keep you posted if I figure something out.

Have you guys checked your APNs?
Tmobile has it set as a web2go plan.
Go to the the "acess tmobile" app and go to your plan and click upgrade. Done. Plan stays the same and everything works again.

I can't even go to any websites on my phone without wifi. When I tried to open that app it wouldn't let me because it said that I can't use wi-fi with it.
And I did "check" my APN, I don't really know if there's anything wrong with it. I'm actually doing this for a friend and I have a Sprint SG3 that I rooted with absolutely no problems. This t-mobile phone though is really trying my patience.
try it again. turn wifi off and run the app. It should take you to your account.
Just go return it then get another phone.
The phone will literally not connect to ANYTHING data related unless on a wifi network. Unfortunately this t-mobile app will not work over wifi so I'm still stuck on what I can do.

FIXED! - No LTE

Hey guys. I'm kinda stuck here. I am getting no LTE service on my phone at all. Of course those idiots at straight talk keep saying im provisioned for it but nope, not getting it. I tried everything I can think of from factory resetting to apn settings and nothing. When I go into my network it bounces between HSAP and HSPAP but no LTE. I live in an LTE service area and was getting LTE up to about a week ago but then suddenly it was gone. Any ideas as to what I can do?
Can ask what are your APN settings?

I don't understand what's goin on. It just doesn't work anymore for some reason. And ST troubleshooting is non existent. All they tell you is to put in those apn settings and it should work. Well it isn't dumbasses!....lol
Also port :80 . I have straight talk too. Your apn looks right
My wife has the Optimus g and her LTE is working just fine. WITH the same APN settings! The last thing I remember doing was going through the hidden service menu but I didn't change anything in there. There is nothing you can change in there to make your LTE stop working. I know with some phones you can but not with the OGP.

Ok guys. I got the issue resolved. I used this method here - http://forum.xda-developers.com/showthread.php?t=2351041
The only issue I had was for some reason I couldn't manually edit the build.prop. I had to install JRummies Rom Toolbox Lite and that did the trick.It's so nice to have my LTE back!
Thanks for the link. Always liked to manually set to 2g or 4g when lte was weak. One reason I always installed custom roms and didn't stick to stock.

Personally I don't worry too much about it. Being on stock with this phone gets great battery life. So no need to turn off the LTE to conserve battery.

[Q] Help with APN settings

I want to start off by saying sorry for posting with a new account, I know that is frowned upon on forums, but I need help with a phone that isn't even mine and I've been trying to figure this out for a week now. I've searched everywhere and I figured it's time to ask the experts. Here's the story.
So my girlfriend got a Samsung Galaxy S3 (previously on T-mobile, model number T999) used and got a Straight Talk plan. I put in an APN for Straight Talk and everything was hunky dory. She didn't like the battery life so I rooted the phone and put cyanogen mod 11 on it (which is really friggin cool, so happy I did that) but it didn't save the APN settings. This is where I'm a dumbass. I didn't write down the settings and I didn't back up the phone (she doesn't have anything on the phone worth restoring, or so I thought, those precious APN settings were there) so now I'm trying to find the new APN settings. Everyone has a different set that worked for them, I can't get any of them to work. I know that the MCC is 310, but I don't know if the MNC is 410, or 260 (I believe it is 260 because that is a T-mobile MNC) if you don't have the proper numbers then it won't even save the APN settings. I have yet to get any settings to actually save which is very frustrating. Any suggestions?
I thought Straight Talk was an AT&T mvno.

I believe it is both. They use towers from Verizon, AT&T and T-Mobile. I think that whatever your phone was on originally is the set of towers that it uses. I've seen APN settings with 410 and 260. IIRC 260 was the MNC that worked before.
There are posts all over xda that have apn settings. Best I can say is to search them out and try them.
It could be a cm issue though. They updated their radio files to work with kk modems and its caused lots of problems for people who have older ones.
