Set a SIM PIN Lock
A PIN is the identity code of a SIM card, and can be set as the SIM card lock. After doing so,
you will be required to enter the correct PIN to unlock the SIM card every time you power on
your device or switch to a new device to prevent unauthorised access.
You need to obtain the PIN of your SIM card from your carrier before using this function.
1
Go to
Settings > Security > More settings > Encryption and credentials to enter the
SIM lock setup screen.
2
Enable Lock SIM card, enter the PIN code, and then touch OK.
To modify the PIN, touch Change SIM PIN and follow the instructions.
•
You will have to enter a PIN Unlocking Key (PUK) to unlock the SIM card if you exceed
the maximum number of failed attempts to enter the PIN. A new PIN needs to be set
up once you successfully unlock your SIM with a PUK. Should you also exceed the
maximum number of failed attempts to enter the PUK, your SIM card will be blocked.
•
The PUK can only be obtained from your carrier.
