Unlock device/ Bill assistance
I have been trying to unlock my previous phone through AT&T unlock device online but it keeps telling me that I have to pay off the device first. Error message: "Looks like you haven't paid off your device yet. Follow these steps to pay off your installment plan. Then, wait 48 hours before you submit a new request.
The device contract was terminated but I paid my debt to your third party company. How do I go about finding out if it is truly paid off and how can I get the phone unlocked?
