Gazelle isn’t giving you $800.Not saying you're wrong, just trying to work through it in my head.
Sites like Gazelle, etc... how do they know if a phone is still under financial obligations when someone sends one to them?
Besides that, I would assume plenty of phones out there are paid off and still carrier locked. AT&T themselves will not unlock it unless you submit a request.
😉
There are online IMEI checkers that will tell you if the phone is blacklisted but I don’t think they can tell you if they’re paid off or not.
The one I tried definitely couldn’t.
But do you want to risk losing the $800 if AT&T denies you?
Id stick with an AT&T or unlocked phone.
