I have unlocked my old GSM phone service with AT&T and it does not work with my AT&T sim card, does any one want to sell their old GSM phone serviced with AT&T?????????
You may be able to find a suitable GSM phone right here. Check out the GSM Buy Sell Trade Forum to see if anyone has what you're looking for. You might also want to put your post in there too. Good luck!
Good luck!
