I have a tricky problem with me blackberry 8310 (AT-T) unlocked, i moved back too south africa and took the phone with me. Got a new sim card, loaded some new numbers to the address book, now everytime i try to make a call from the address book its adds a one in front of the number and cancels the call.I can make calls by typing the number in. The same with incoming calls it it says the person is unreachable. Any suggestions
