Very disappointed with this purchase. I called before buying to confirm that this phone was Unlocked as listed. The one I received was not. It is looked to AT&T. Would not work with my T-Mobile SIM. I hired an unlocking service to try to unlock it, but they were not able to do a code unlock. There is a more complicated unlock, but it is quite expensive. Label sent with phone said UNLK and also said that the software version was 1.31AT and it was actually 1.215AT. Seems I am now the owner of a little tiny Kyocera brick that cost $104.99
