I sent my old iPhone 4S to my friend.At the moment it does not have service but he is connected to wifi.iMessage is not working and hoping anyone knows why. I used iMessage before when I had no service on the phone with wifi. I reset the phone before I sent it to him.Is there something in settings he needs to do for it to work? Thanks in advance.
