Will T-Mobile service work with an unlocked SIM free phone?
Hi you can use t-mobile sim in any unlocked phone which is unlocked from GSM network provider ..Else if the phone is unlocked from CDMA network then it can work only with any CDMA network and not with GSM networks like t-mobile ,at&t and so on …If you want to unlock any mobile from network lock to use it with t-mobile sim then have a look at sites like Classicunlocking.com who render unlock code for all mobile models at reliable cost ..After unlocking your phone from GSM network you can freely use it with any GSM sim in any countries.
