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 you set it up, you will be required to enter the correct PIN to unlock the SIM card every time you power on your tablet or switch to a new tablet to prevent unauthorized access.

If you have entered a wrong PIN and exceeded the maximum number of attempts allowed to unlock the PIN, you will need to enter the PIN Unlocking Key (PUK) then reset the PIN. If you exceed the maximum number of attempts allowed to unlock the PUK, your SIM card will be permanently blocked.

The PIN and PUK of your SIM card are provided by your carrier. The number of digits and maximum number of attempts allowed to unlock your PIN and PUK are subject to your carrier.

  1. Go to Settings > Security > More settings to enter the SIM lock settings screen.

  2. Enable Lock SIM card, enter the PIN, then touch OK.

    To change the PIN, touch Change SIM PIN, and follow the onscreen instructions.

This feature is not supported on Wi-Fi only tablets.
