with the SIM card. For details, contact your service provider.

If you enter the incorrect PIN a specified number of times, the
phone prompts you to enter the PUK.
If you enter the incorrect PUK a specified number of times, the
SIM card will become permanently invalid. If this occurs,
contact your service provider for a new SIM card.
