First of all make sure your data is on. If that does not work then check your APN settings. Just let me know if that helps!

If all else fails you can flash the stock ROM via ODIN and get a fresh start.

data is on. what is apn settings?

here is what i have going on. this is an at&t gs3 on straight talk (ST). i rooted phone. was old version of android so i updated to 4.1.1. via stock rom in odin. now data dont work. i want to go back to ics to see if that helps. the stock ics i have is in .rar and wont run in odin. im not opposed to custom rom. i just need this to work

the mistake i made is not backing up before making changes.

No don't go back change the APN settings. Go to settings->more settings->mobile networks-> access point names-> click the plus button-> then put this.

Name:Straight Talk
Apn:tfdata
skip down to Mmsc
Mmsc:http://mms-tf.net
Mms proxy:mms3.tracfone.com
Mms port:80
