I have phone T-Mobile and I ‘m that question as you can find the code or program that you can use to unlock Blackberry 7290 and the sim card so I can switch services for Sprint as carrier.

  1. Hi Chez
    You can not use a T-Mobile phone on the Sprint network. Sprint is CDMA, T-Mobile is GSM. It is 2 different technologys, not compatible with each other. That phone unlocked can be used with ATT, not Sprint or Verizon
