How to Check a Phone Before Selling It Online

Buyers are not the only ones who should run checks. As a seller, a quick lookup protects you from disputes, returns and accusations of selling a bad device.

Confirm it is not blacklisted

If the IMEI ends up on the blacklist after a sale, the buyer will come back to you. Run the GSMA Blacklist Check first to be sure the device is clean.

Remove the activation lock

An iPhone still tied to your account is useless to the buyer. Verify it is released with the iCloud Activation Lock Check before shipping.

Know the value

The Full IMEI Check shows the model and carrier details, and a warranty lookup shows remaining coverage — both help you price the phone fairly.

Bottom line

Check before you list: blacklist, lock and model. A verified phone avoids headaches on both sides.
