I wouldn’t buy a phone at AT&T: if if you pay in full , and you ask for an unlock phone, the sim is still locked (which they don’t tell you) and when you ask to unlock it because you want to change carrier, they will say it’s impossible, no matter how many years you have been with them. In the shop they said they are not going to help you unlocking the phone because you are not coming back. Horrible experience unfortunately
