code. In such a case you will have to contact your service provider for a PUK code to unblock your SIM card.

When SIM PIN lock is enabled, you can change the PIN code.
PIN2 code
Your phone supports advanced feature that may require a PIN2 code to be entered before they can be accessed or modified. Entering your PIN2 code
