So I had this problem a few days ago but i thought it would end and work just fine afterwards, but now it's back. So what seems to be happening is I will have my phone on for a while, then after about 5 minutes (after it starts happening) then i will start not receiving/being able to send messages. It's starting to really piss me off. It shows i have full 3G connection with 6 bars of connection, yet i can't send or receive messages?
I use AT&T
