Is it possible to use SelfServe to unlock my iPhone. I don't see the "Mobile Services" dropdown that the Help entry describes. I suspect it's because I have a "prepaid" account.
Send them a message via Facebook messenger. Be sure to include the imei number of the phone. (you can check this by dialing *#06#). They'll unlock the phone for you, although it may take a day or two depending on just how busy they are.
