The PIN protects your UIM card from unauthorized use. If you enter
wrong PINs three times accumulatively, the UIM card is locked. In this
case, you can enter the PUK to unlock the UIM card and change the PIN.
The PIN and the PUK are provided with the UIM card. If they are missing,
forgotten, or not provided, contact your network operator.
To set the PIN, do as follows:
1.
On the main menu screen, tap Settings > Security > PIN Code
Request.

Tap On to enable the PIN or tap Off to disable the PIN.

Changing the PIN
