using at&t s4 on t-mobile, better than using t-mobile s4 on t-mobile?
Hi, I'm looking to get t-mobile service. Does it make much of a difference if I buy an at&t s4 phone and unlock it, vs. using a t-mobile s4?
I unlocked one at&t phone and it can make calls, but not use data on t-mobile. what gives?
Can I use the hot spot feature on the at&t phone?
Can I put a t-mobile ROM on the at&t phone?
