Unlock I watch
I bought a iwatch off a website and it won’t pair to my phone
Question marked as
Unfortunately there is probably nothing you can do to get the activation lock released. The fact that you are asking here probably means you have tried to contact the seller but he has disappeared. We see this problem frequently here at ASC, and in many cases the sad truth is that the locked device is in fact stolen.
