Phone won't connect to mobile data after flashing - T-Mobile, Samsung Galaxy SIII

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.

I've made some progress. My coworker has a t-mobile gs3 so I switched out the sim cards and it works. So I guess it's something with the sim card...

[Q] Getting only Edge (2g) speeds any tips?

Just got the GN (GSM Unlocked) and was mainly getting to know it on WiFi. Recently I popped in a SIM (Tmobile on the 30$/month prepaid 100 min/Unlimited Text &Web). The problem that I'm facing however is that I am stuck with only 2g speeds.
Do I have 3g/4g coverage?
Yes. I somehow got it to work for all of ten minutes while messing around in the *#*#4636*#*# menu but ended up running into a bug where I couldn't switch out of the European Band and so I had to do a Factory Reset.
So now I'm unsure as to how to get those signals back. I am on a modified APN setting for Tmobile:
APN: epc.tmobile.com
Proxy: not set
Port: not set
Username: none
Password:blank
Server: blank
MMSC: (ht)tp://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Proxy: 216.155.165.50
MMS port: 8080
MCC: 310
MNC:260
Authentication Type: Not set
APN Type: not set
Any help would be much appreciated. I am running the stock ROM (considering I had to do a factory reset). I have data enabled as well as roaming. I do not have the 2g box checked. Hopefully this provides enough information if not please let me know.
It should just work without you having to mess with anything..

Worked for me automatically.
Problem Solves (no intervention needed)
So hopefully if anyone sees this post they will learn the art of patience like I did. Turns out it just takes a bit of time for Tmobile to recognize that you have actually paid them.
I went to sleep and when I woke up I received a text message from Tmobile saying, "Thanks for the 30 dollars" and I was getting H, and 3G speeds. Issues sometimes resolve themselves I guess. Thanks to everyone who replied.

Yeah if you're registering a new line or SIM, it can take up to 24hours for it to become fully active. Glad your problem fixed itself.

Unable to wireless tether GSM Nexus, Help?

I can't seem to get wireless tethering to work. My GSM Nexus is rooted. The WiFi Tether app runs as it should but the APN never shows up in wireless network lists. I used the same app flawlessly on a rooted Desire. I'm on Vodafone who actively promote using phones for tethering so there is no issue there.
Running stock Android 4.1.1. Root is checked and confirmed with Root Checker. SU appears to be up to date.
Any suggestions greatly appreciated. Thanks
try selecting your phone model in the wifi tether app settings.
For me, it would always say "connected" but no other information and would not show up on wifi networks. I selected Galaxy Nexus in the settings of the app ( even though Im on a HTC VIVID, just for one more day until I get my nexus) and the second time after connecting, It also displayed upload and download realtime information.
Somethings you just have to nudge these things a bit
Have you tried turning on the WiFi tethering via the native settings menu, rather than an app?

Thanks for the suggestion but I've already done that. I tried Auto, Generic, both Nexus options and the Galaxy S2 options plus a couple of other randoms from the list just for good measure. None seem to work at all. I've also tested the APN on a laptop, my TF300T pad and my old Desire and it doesn't show on any of them so it must be the Nexus at fault.

Yeah, I did. It connected but I couldn't surf at all even with good 3G/H reception. I tried both wifi and BT using my ASUS pad.
I just got my nexus, a few hours ago.
I set up my phone, I am on AT&T (without a wifi plan, grandfathered into "unlimited" )
I turned on wifi hotspot, system wifi hotspot not a playstore app.
and...well..it works for me without any problems.
I did add the at&t pta apn. I know its not an LTE phone, but the PTA apn has pretty good service compared to the others.

if you are on AT&T try adding the pta apn and see if that helps?
if on a different network, search and see if you can find other apn settings.

Unlocked the T-mobile phone to work on AT&T, no data usage. HELP!

I got a Samsung Galaxy SII T989 new, for free, off of my uncle who gets phones for promotional purposes. It's a T-mobile phone, and I'm on AT&T. I paid for an unlock code and successfully unlocked my phone for use on AT&T. I can text, call, and use WiFi, but can't get the data to work. (I also can't send or receive MMS messages, not sure if it's related. HELP!

couple things have you asked on the AT&T forum and have you done a google search on how to get your Tmobile phone to work on AT&T?
next is have you changed or rather added the new apn? if any of this is an issue for you I would say your best bet is to trade the phone on craigslist for someone with the skyrocket.
since the two phones are interchangeable as far as roms go I would suspect with a little more digging you will find your answer... check here

^ +1 apn should do the trick, pretty typical for unlocked phones to not have the apns on the sim. Manual programming is going to be fun if you are new to android

Can't get on Bell network

Just got my phone back form being fixed (cracked screen, yayyy). Prior to fix it was rooted and everything was working great.
I get it back and had the following error: Unfortunately the process com.android.phone has stopped.
This came up twice each time the phone was rebooted/ turned on.
So, from various searches on this forum, on androidforums, and random google results this was my process:
The phone was rooted, so I un-rooted it with SuperSU and then did a factory wipe and went through the day one set-up process again.
deleted contacts and remove all accounts
clear phone cache
clear contacts cache
restored stock firmware (phone had to be rooted, so is now rooted again)
software has just been update OTA
reinstalled stock firmware using Odin3 (used Triangle away to clear count, device status was back to normal)
That fixed my error problem, but I still had no connection to my Bell LTE network. Wifi was fine, sms good, calling good, MMS not good.
I found the APN settings on this forum and created a new one using these:
APN Name: Bell LTE
APN: pda.bell.ca
Proxy: web.wireless.bell.ca
Port: 80
Username: <Not set>
Password: <Not set>
Server: <Not set>
MMSC: http://mms.bell.ca/mms/wapenc
MMSC proxy: web.wireless.bell.ca
MMS port: 80
MCC: 302
MNC: 610
APN type : <Not set>
Still didn't work, and when I restart the phone the new setting deletes itself.
So I installed two different modems as found here: http://forum.xda-developers.com/showthread.php?t=1831898
I tried I747MLALH1 first and current have I747MVLLE8 installed.
Phone is now rooted again (from installing new modems). Running 4.0.4. Device status is "Modified". Mobile Network State "Disconnected".
WTF is going on here? New SIM card maybe?
Any help would be great, but you'll have to dumb it down a little :cyclops:
Here are my settings.

My default APN settings are the same as those. Now, when you hit the *back* button once from that screen it takes you back to the list of APNs (though you probably just have one called "Browser"). Is the circle on the right highlighted with a green dot or is it unchecked/ empty?
Thanks for the help
It is checked. Filled with green dot. And below Browser it says pda.bell.ca

Good for you. I found it a bit confusing at first. I had to re-read it a few times before I attempted it. I had lost my IMEI as well as DATA ability on my Roger's S3 and this page helped me! As to how I lost it....??? Some byproduct of flashing.

Problem solved.
I skimmed through the info in the link @themadproducer provided but it didn't sound like that was a solution for me
Went into the Bell store, immediate the guy saw I didn't have an LTE SIM card so he said he doubts that is the problem but atleast when it is fixed I will have 4G internet. This was the original SIM I got back in June when I bought the phone, so I guess I was running 3G and didn't noticed since it was still blazingly faster than the 3G on my Blackberry.
We ended up calling a Bell diagnosis tech and he went backdoor on my phone, when I got it reactivated after being fixed the lady at the Bell store forgot to change/ add some things.
Good as gold now! My wonderful 6GB LTE plan is finally working and I'm not wasting money on nothing!
Thanks everyone for the help and input, much appreciated.

[Q] mms working with Cricket?

I've followed most of this thread (http://forum.xda-developers.com/fire-phone/help/guide-fire-phone-fireos-google-apps-t3206603) along with updating to 4.6.6, to set up my fire phone, and almost everything is working. I've activated the phone with a Cricket sim, and I can get internet and sms fine. I still can't get mms to send or receive. I've tried several different APN settings from the Cricket website and others. I've tried using the stock messaging app as well as handcent.
Is anyone else using Cricket with their fire phone and able to send/rec mms? If so, what are your APN settings?
My wife's fire phone is working with Cricket, including MMS. I think Cricket takes up to 24 hours to re-reoute SMS/MMS correctly. Maybe give it a day and see if it fixes itself.

So it does work. That's good news. Turns out my wife's BLU phone doesn't work either. It's been over a week since she switched.

I would have to wait until tonight to check her phone, but my Nexus 5 is working with those APN settings.
Well, it turns out the fire phone is set to use the AT&T APN. The Cricket APN is there on the phone, but the AT&T one is selected. And everything is working fine on her phone.
Here is a thread from howardforums that describes this same situation.

Also, I neglected to mention that I use Google Voice, so all my SMS/MMS gets routed as data. Which is why I thought the Cricket APN worked for my Nexus 5.

Thank you more times than I could ever say! I have a carrier unlocked LG H830 (G5), and have spent more hours than I'd like to admit trying to get outgoing MMS to work on Cricket Wireless. You name it, I've tried it. I would never EVER have thought to change the Network Mode. That fixed it. Granted, instead of showing "LTE", it's now showing 4G (3.5G), and my data speed down is about 5MB, but Cricket throttles the down speeds anyway. And, at home on Wifi, it doesn't matter anyway. So again, thank you!
For the purposes of future Google searchers:
For outgoing MMS to work on a carrier unlocked LG H830 (LG G5), the Network Mode must be set to GSM/WCDMA.
Regards,
Mark
