Go to this settlement site. Look for the “submit a claim online” section. You can also submit a claim by mail. You’ll be asked to provide the phone’s serial number. If you don’t have your phone’s serial number, you can search the database to find your serial number by submitting your Apple ID, device type, name, and address. Once you’ve submitted your claim, you’ll receive a claim ID and a code via email. Later, you can use this code to look up the status of your claim. That’s it!
