Tmobile service problems after rooting - Galaxy S III Q&A, Help & Troubleshooting

Hey guys I just rooted my Samsung galaxy s3 GT-l9300 and I've been having problems with the service. I I sometimes have service and some other times I don't, also with Internet access I can't access it unless I'm in wifi, and I do have 3G access can someone help me? This started this morning and I rooted my phone last night, everything was working perfectly before.. I can't even send a picture message, it says there's a problem with the server. Thank you!

Stock 2.2 wifi calling problems

So my wifi calling on a stock 2.2 vibrant, upgraded with kies mini, was working yesterday and now all of a sudden it says some error or tmobile network but I get full bars near a window, and in settings and the notification bar it says t-mobile network and also says my data is 2g. I dont know what went wrong but I kinda liked wifi calling and want it back, if possible without reflashing my phone. I tried erasing user data cash factory reset all that good stuff and even ran it from the start but nothing. Help would be appreciated greatly and thanks to anyone who does.

Have you tried 3G and Wifi?
Despite otherwise claims by Skype/Microsoft, the protocol is quite easy to detect and block in case your carrier doesn't like Voip.
On another note, Skype doesn't work reliably for me on either mobile phones or desktops: keeps loosing connection or not seeing online contacts.
Yes. I have tried wifi, 3g. Still no connecting.
I have read thet people have problems with galaxy 9300 and skyoe. But cyanogen solved problems for them. For me not
I have even tried chanogen jelly bean. Still not connecting.
Internet is ok. Strong and good signal. Strange.
Maybe someone has anh ideas?

[Q] SMS Problem

I usually don't ask questions. I solve them myself. Now I have a problem I don't know what to do. I can send SMS, use Mobile Data, make and receive calls, but I cannot receive messages. They don't show up. I am on the AT&T network. Everything worked until one night, it just stopped working. Couldn't get texts. Being a teenager, that is problematic for me XD. I have been to two AT&T stores (local and corporate). They wouldn't help me since it wasn't a branded AT&T phone. Wow. They take the money no questions asked. The part that confuses me is. I didn't do anything to my phone the night it stopped working. Anyone have any thoughts.
-Done so far= Flashed to stock, factory reset multiple times, checked message center #

So after a week same problem. Everything just stopped. This really pisses me off since I can't use my S3. I am back on my Captivate for the time being and it sucks now that I have experienced the S3. Anyone have any ideas what it is?
Sudden death syndrome is a good guess......

I usually don't bump but this is preventing me from using my phone.

I guess nothing... Great. I have to use a super old phone until i can afford another one. Not easy having to pay a 3000 dollar insurance policy and for my motorcycle. Not easy when you are 17

The only things I can think of is, have you got another messaging app messing things up, or in the messaging settings there's a spam settings, have you checked that?
Sorry if you have already checked these
Checked it and its off. I don't have or use anything but the stock SMS app.

I think as default the spam settings is on, at least mines on. Might be worth a try.
Also did you restore your old messages when you went back to stock, if so maybe try deleting all messages, clear data in app manager. Back up your messages before deleting though
Yeah i deleted everything. Flashed stock and tried. Nothing. It makes me mad that i cant use my phone.

just to clarify - the new sim card worked for a week or so on your S3 and stopped working. while the same sim card(with an adapter) works on your captivate ?
i want to figure out what's the source of your problem.
other thing - if i understand you correctly you went to AT&T to fix your phone. i suggest go to AT&T center or call their support cause every company has a number for checking sms transportation and see in what stage it failed. it's just sending a code to a certain number and you should get the desired info.
i really don't think it's a software problem
Here are the details. One night i noticed i wasnt getting text from a specific someone and it was weird. Within the next couple of days i went to AT&T store. Got a new micro sim for my S3, didnt work... Got a regular sim and put it into a old phone they had lying around and it worked. I then had them cut it down to micro sim and put it into my S3. Worked for about a week and stopped again. Got a new regular sim and put it into my Captivate and it worked. So im on that until i have it fixed.
Spam off
Sms center number right.

If I were you, I would try with another operator's sim card to figure out if the problem is on att network or the phone. Maybe get one of those pay-as-you-go/prepaid plans and try to receive an sms- if it works, then the problem is on att's network
Thanks i will see if one of my friends will let me.

When you put your sim in your Captivate did all the missed messages come through on the Captivate. If they did then I would say it's an issue on the S3, if not then it's probably an at&t issue
All of them came through yes. But why would it not work on the S3. And randomly? There was another guy on the forums that had the same problem.
