Restoring a SIM card that has been locked out

Important: You need a PUK code to restore access to your SIM card. You can get this code from your mobile operator.
  1. On the Phone dialer screen, enter the PUK code, and then tap enter.
  2. Enter the new PIN, tap enter, and then reconfirm the new PIN.
