What are differences?

Like most of you I paid for the iPhone 6S Plus outright from Apple. The only option there was (the night of the pre order on the 12th) was the T-mobile non-contract iPhone. Is there a difference between this phone and the one you'd get from ATT? (I use ATT not T-mobile) Just wanted to ask.

I believe the ATT ones are locked to their system.

^ It's locked to AT&T if you grab it directly from them. If you pay full price at the Apple store then it is unlocked, otherwise there is no difference. Verizon just has more bands compatible with CDMA and GSM networks, though.
