If my AT&T phone on a contract breaks can I just buy a cheap AT&T prepaid go phone and put my sim card into it and use it or does it need to be unlocked or something? Mozilla/5.0 (iPod; U; CPU iPhone OS 3_1_2 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Mobile/7D11
Yes, you just put your SIM in the prepaid phone and it works fine. I had that happen to me. My phone broke, I went to AT&T store, sold me prepaid phone, put in SIM card and was calling again.
