D Dopeyman macrumors 6502a Original poster Nov 19, 2016 #1 I'm interested in purchasing a 6s. The person selling it says that it's carrier unlocked and that my AT&T sim will work. I always thought that a AT&T sim will not work cause Verizon is CDMA and AT&T is GSM. Who's right and who's wrong? Thanks!!
