Since this morning, my Samsung S3 won't use data at all. I've tried turning the phone on and off, turning the data on and off, etc, but it still won't work. I don't get it, because I've used 1.6 GB of my 2GB plan for the period, which ends on the 25th, and I don't believe my plan has been changed at all. It still connects to WIFI, but I can't use the internet unless I'm at home. Suggestions??
