Lol, no one here knows a lot about cells, its "network security". Also keycodes just tell you "hidden" info about you cell. This depends gratly on brand and model number. Im fealling nice, so ill let you in on a little secret. Tracfone is fairly secure. There is only one way I know of but this involves ruining the phone after the month, calling ppl that will be willing to play dumb after interigation, and owning a phone that hasent been made in about 3 years.
My sugestion is to go out and buy the att go phone, wich starts at 20 a month, dosent need to be registerd in your name, and dosent require a service agreement. Otherwise tmobile is good if you can commit to a years worth of service.
