i have an iphone 4 for a while. recently my phone wouldnt send or recieve text messages. i tried the sim in a different phone but it still didnt send text messages. do i get a new sim card or wht?
That would be your first step. If your Sim wouldn't work in another phone, then it may be bad.
go to the AT&T store have them try a differnt sim card in it. if that does not slove the Problem make a appointment with the Genius bar have apple look at the Iphone. maybe it has bad hardware and needs to be relaced under warranty.
