i bought a new prepaid activation kit and activated it with the IMEI from the iPhone.

my phone's unlocked with anySIM, but i get no service in the exact same spot as i use the phone with the original SIM.

i know no service has been an issue, but the phone's definitely unlocked and i'm pretty sure i went wrong in activating this prepaid card without a prepaid phone.

then again, the at&t site says the card is activated. another thing is, they send a text message with a code to login to your account which i have NOT received.

point me in the right direction? should i go ahead and buy a prepaid phone (they have one for $10), activate it and use that SIM? will it work?
