AT&T router was used several years ago with AT&T contract.
The service was stopped a while ago. I want to unlock the router.
I have tried several times online.
I got several different denial messages. One time it said the device was under contract. NOT! Another time it said it wasn't an AT&T device. NOT1 It has AT&T all over it.
I need help. Very simple IMEI [Personal IMEI Information Removed]
What is needed to unlock?
