Which version of an unlocked Note 5 should I get? So confused by all the different models. I read that Samsung Pay isn't available on the international models which is a bummer. I have AT&T, planning on swapping my SIM from my iPhone 6S+ and Note 5 from time to time. Noticed AT&T just started to offer a 64GB in Gold, but that price...not sure what to do! Help! Really wanted to use Samsung Pay...
