Learn how to setup SIMCard lock on your Huawei Ascend P6. The personal identification number (PIN) is delivered with your SIM card. If you enable the PIN protection function for your SIM card, you will need to enter the PIN each time you power your phone on.
Before you perform the following operations, make sure you have obtained your SIM card’s PIN from your service provider.
-
On the home screen, touch Settings icon then the All tab.
-
Under PERSONAL, touch Security.
-
Touch Set up SIM card lock.
-
Select the Lock SIM card check box.
-
Enter the PIN.
-
Touch OK.
Note: If you incorrectly enter the PIN a specified number of consecutive times, the PIN is blocked and the phone prompts you to enter the PIN unblocking key (PUK). If you incorrectly enter the PUK a specified number of consecutive times, the SIM card will be disabled permanently. For details about the maximum retry attempts for the PIN and PUK, contact your service provider.
