Looks like your IMEI and phone number don't match
I have an iPhone 6 Plus that was purchased by my daughter and it was paid in full when she upgraded. When I received it I purchased a prepaid plan and found AT&T does not have good service at my residence. I made an unlock request and received a message that stated it could not be unlocked until the phone was active on my plan for 6 months. I begrudgingly kept the phone active for the required 6 months and when I attempted to make another unlock request, I get the following message: Looks like your IMEI and phone number don't match. I don't understand how it matched before and now that I have fulfilled my obligation suddenly my IMEI and phone number don't match?
