Interestingly, the model numbers SM-N900A, SM-N900T, and SM-N900V have shown up here. They are expected to be the AT&T, T-Mobile and Verizon Galaxy Note 3 models respectively. Oddly enough, the AT&T model is listed with a 6-inch display like the T-Mobile model while the rumored Verizon variant is apparently being tested with a 5.7-inch display. - GottaBeMobile
Samsung Galaxy Note III could be available in Three different Screen sizes(5.5 inch,5.7 inch and 6 inches) - TechKiddy
One T-Mobile for me please.
