To find out if your phone has been reported, you can use our FREE preliminary IMEI check to see if your phone has been blacklisted due to theft, loss or unpaid bill. For a more comprehensive check per network carrier, request a full Blacklist Status Phone Check. This service is valid for all phone models.
