Is there a password on it? If not just look in the phone book and see if there’s a “mom”, “dad”, etc.
Otherwise, assuming you’re willing to go the extra mile – turn it into its respective store (Verizon, AT&T, etc.) and they’ll be able to look up the user with the IMEI # (just have to remove the battery).
Yes, there’s a password lock. I’ll go to the ATT store when weather permits. The whole thing’s taken apart and in a bowl of rice to dry out. It’s wet & muddy.
