    T-Mobile unlock app – Before proceeding to order the unlock service from us, just make sure to check that the APP is working correctly. When using the APP it should initially say " Not Eligible for Unlock ", if you are getting the messages " Communication Error " or " Server not responding " Please try again later or Error code = 255 " then do not order until you find a way for your phone to communicate properly with the server.
