So I'm trying to unlock my ATT phone (Samsung galaxy s6 edge), but I don't have a phone number for it and trying to activate it with a different SIM card. Is there a way to unlock it without the phone number?
Just make sure to choose the "not an ATT customer at this point", if that's true, and watch for the confirmation email.
Responding to the instructions in the confirmation email is critical, otherwise your request will be "stalled", and eventually "time out" (in a few days), requiring re-submittal.
