What do I need to do if “Enter PUK code” is displayed?

1. Following three consecutive failures to input the correct SIM card PIN code, the PIN code will be blocked and the request for the PUK code will be displayed.
2. Before attempting to input the PUK code, ensure that you have the correct code provided by Network provider.
3. After ten unsuccessful attempts to input the PUK code, the SIM card will be permanently disabled.
4. Once the SIM card is permanently disabled, you will need to purchase a new SIM card.
