I just unlocked some iPhones for some friends that are traveling here from Jamaica. I Jailbroke and unlocked the phone and inserted their Digicel sim card. The phone now reads ATT on the carrier info but fails to transmit calls.
I clicked carrier on the settings icon and it gives me the option of AT&T or TMO. Anyne have any idea on how to get this to work or does this particular sim only work in Jamaica??? Thanks for your time
