AT&T refuses unlock my fully paid off iPhone 11
I have an 11 Pro Max that I paid off earlier this year (after the usual 36 month installment) and would like to give it to someone who could use a new phone since I already have the 14. I have tried unlocking it through the AT&T website but it gives me an error saying “Your unlock request was denied because the account information doesn't match our records.”
I have also tried filing it saying I do not have an AT&T account and get the same result. I tried calling support and they’re saying that I had the phone replaced by Apple 2 years ago under warranty and that they can’t unlock it because it’s not the same phone I got when I signed up for my plan. This is insane. I had an iPhone 7 that I purchased through AT&T and paid off and unlocked with no issues, I know for a fact I had that phone replaced by Apple.
How do I force them to unlock it? This is infuriating.
