A:AnswerOpen box means that it has been opened . Brand new iPhone hasn’t been opened . Basically with the open box it could be refurbished or still like new . Either way opened or brand new it’s still a great phone to purchase.
A:AnswerIf it’s a nano SIM card it should work with 11 pro Max sim tray there shouldn’t be a problem . If you like you can always get another nano sim and port your number to that sim to fit your pro Max . But a standard and micro sim doesn’t fit only nano sim fits into the iPhone SIM card slot . I hope it all works out for you
A:AnswerNo, I bought it unlocked, you have to make sure to tell them, or when you order online, that you need the phone unlocked, so you can use it with any carrier.
Also, please note that if you also intend to use this phone internationally, by placing a sim card from the country you are in, you need to be specific to ask for both nationally and internationally unlocked,
Unlocked phone will cost you more though
