Unlock a device involved with H2O
I finished my iphone 7 contract 2 years ago, and I made the biggest mistake switching to H2O before unlocking this phone. When I tried to unlock it last week, I got "Looks like the device you want to unlock is active on another AT&T account. " message, and after a week of researching, I saw someone in the forum got into the same problem- the iphone was locked into H2O, or seemingly another ATT account. I really don't know how to get out of this grey area. Please help.
