Personal Identification Number (PIN) Code
The SIM card has two security codes: PIN code and PIN2 code. For details on the PIN/
PIN2 code, contact your service provider.
PIN Code
This is a four to eight digit security code to prevent another person from using your SIM
card without permission.
If the PIN code setting is set to On (page 246), your PIN code needs to be entered to use
your phone each time the power is turned on. You can change the initial number set at
the time of purchase (page 247).
PIN2 Code
This is a four to eight digit security code that needs to be entered for operations such as
modifying data saved to the SIM card. You can change the initial number set at the time
of purchase (page 247).
PUK (Personal Unblocking Key) Code
If the PIN code or PIN2 code is incorrectly entered three times in a row, the PIN/PIN2
lock is set. To cancel the PIN/PIN2 lock, enter the PUK code or PUK2 code. For details
on the PUK/PUK2 code, contact your service provider.
