You can’t! This will not work.

One because Sprint phones don’t use SIM cards. (the old ones don’t)

The main reason being that when a phone is manufactured it is manufactured to work only with a service that is alike.

Examples, Cingular, ATT and T Mobile use SIMS cards
Sprint and Alltel do not.

You can only unlock a gsm phone to work on gsm service.
Your trying to unlock a Digital phone to work with GSM service. The services aren’t compatible. It won’t work.

What do you think? Answer below!


  1. Sprint will NEVER work with a T-mobile phone. Sprint ONLY can use Sprint phones.

    T-Mobile uses GSM phones. It obviously has a SIM card.

    Sprint uses CMDA phones. It does not have a SIM card.

    These two networks are not, and will never be, compatabile.

    You’ll need a new phone.
