iPhone 7 network locked
I have moved my iPhone 7 to a new carrier from
AT&T. The new carrier says the phone
is locked and cannot be used on their network. Can it be unlocked? I see many
internet sites that say they will unlock the phone for anywhere from $20 to
$120. The phone is fully paid for so is AT&T responsible for unlocking it
since I bought it from them? What should I do to allow the phone to be setup on
the new network?
iPhone 7, iOS 14
