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 phone to prevent unauthorized access.
You need to obtain the PIN of your SIM card from your carrier before using this function.
1 To set up the SIM PIN lock, go to Settings > Security > More settings > Encryption
and credentials, then touch Set lock to enter the SIM lock setup screen.
2 Enable Lock SIM card, enter the PIN code, then touch OK.
To modify the PIN, touch Change SIM PIN and follow the instructions.
• You have to enter a PIN Unlocking Key (PUK) code 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 code, your SIM card will be
blocked.
• The PUK code can only be obtained from your carrier.
