You are posting in the wrong forum. This is "CANADA WIRELESS FORUM". Post this at the other US forums and you should get a better answer.

sprint and verizon use CDMA. att uses both TDMA and GSM. t-mobile is GSM only. none of these technologies are compatible, therefore, you cannot use a sprint or verizon phone on t-mobile or att, and vice versa. the only combination that might work is if your att phone is a GSM phone, then you can take the sim card out of your t-mobile phone put it in your att phone. but first you have to make sure your att phone is unlocked.
