SIM card lock
The SIM card lock protects your SIM card, not the P800, against
unauthorized use. It is unlocked by the PIN and PUK codes.
You can find your PIN code and sometimes your PUK code in
the documentation you received with your SIM card. If required,
contact your service provider to obtain your PUK code. (PIN
stands for Personal Identification Number and PUK for Personal
Unblock Key.)

You can choose to have the SIM card locked every time you turn
the P800 on, or to have the SIM card unlocked.
An error message informs you if a wrong PIN code has been
entered. Usually after three wrong attempts (SIM card
dependent) the SIM card will be blocked and you need to enter
the PUK code to unlock it.
The PUK code consists of eight digits. When you have entered
the right PUK code you must enter a new PIN code. You have
ten attempts to enter the PUK code. If all ten attempts fail, the
SIM card will be disabled and you need to contact your network
operator.
You cannot change the PUK code.

Some functions on the SIM card can be protected by a
secondary code feature.
