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.
Are you looking to upgrade and activate your device?
