Unlocking any iPhone from AT&T is not a big task provided you have already paid the full price for your smartphone. Just in case, you are planning to travel to other countries or wish to sell your iPhone 7 and iPhone 7 Plus which is currently locked with AT&T, you might want to unlock your device—either to use other SIM card or have more resale value.
If you haven't yet paid for your iPhone but want to unlock it, you will have to go through a procedure to get it done. When your iPhone is locked to any carrier such as Verizon or T-Mobile, you won't be able to use different network even with a SIM card from other service.
