So I sold both my parents iPhone 4's two years ago. The phones have resurfaced recently because someone had been submitting unlock requests. I typically would not be worried, but my parents have been receiving strange AT&T case tracking emails sent via text message. Here is the strange part... My parents are on a family plan with my Aunt who is the main account holder. After all these strange text messages and emails, I told my parents to call AT&T and see what the cases were referencing. After spending an hour on the phone with them it was discovered someone has been calling in for the past week trying to get the phones unlocked. They told AT&T they were on a trip in China and need to use the phone on another carrier. The scary past is that the individual is impersonating my Aunt and are giving her name and last four of her social... How in the world could they have found her name and last four of social? Let alone know she was the main account holder? Remember these are my parents phones. I always hear people trying to ask the original owners to put in the unlock request but this is totally different... Any insight on how this could have happened?
