I gotta admit I'm not an iphone user, but my wife is and I have to learn.
She wants the iphone X so I have been looking for a slightly used newish one to save some funds. I know about making sure it's signed out of icloud or ilock cleared. What I don't know about is the unlocking. Were on AT&T and I see a lot of Xs that are unlocked. I assume it will work on AT&T but then there is something about it locking as soon as you put in your SIM card. So if I add my SIM card to it to check everything will it be locked to my SIM or to the AT&T network?
On a side note, could I purchase new from the Apple store using their iphone upgrade program and put a big down payment to reduce the monthly costs?
