Help needed! T-mobile galaxy note with At&t sim
My friend gave me this T-mobile version of galaxy note (I'm not sure if it is locked or unlocked) and I inserted my AT&T SIM card.
The phone recognized my SIM and voice calling & text messaging is working fine.
However, it does not have 3G/4G connection.
The only way I can use the data is through Wifi.
Do I need to unlock this phone in order to use 3G or 4G data?
Is this phone already unlocked (since my AT&T SIM is recognized and working) and I need to something else to use the 3G/4G?
