No. The hardware included within the device are not compatible with the AT&T and T-Mobile bands. If you insert an sd card it could be possible to get voice working if the device has a global mode. But that's probably about it if possible. I wouldn't bet on it.I looked everywhere.
Some says that it cannot be unlocked because sprint is different from AT&T and T-Mobile.
Some said it can because of the SIM card.
Anyone found a good method?
