I just bought an mpx200 unlocked from an ebay user. He was using at&t. When i got the phone my cingular sim card worked without entering the unlock code. Everything on the phone works fine. I just do not get n e service and im getting pretty angry because i do not get any where ever i go. My friend just bought the same phone and his is not unlocked and it workds just fine. I tried entering the unlock code without my sim in it and it made a noise but i still get the same problem. I live in the boston area. Any help will be greatly appreciated.
