Ok so this number rang once and hung up. I ignored it and a half hour later it rang again. Same thing, 1 and done. So almost immediately my other phone rang and it was my son with his number showing up on the screen. I said, wrong phone son. He said " I just tried the other phone and it rang a half a ring and went dead". He is in another country today and has a temporary international plan so MAYBE this is the answer to all of our questions about this number???? IDK
