what is the difference between an unlocked Att iPhone 5 and a t-mobil iPhone 5 on t-mobil network?
I have an unlocked AT&T iPhone 5 and I'm using it on t-mobile network. I was told that the new T-Mobil network uses 1900 band for Internet, and the AT&T iphone 5 does not support that same band.
iPhone 5, iOS 6.1.3, T-Mobil network
