P800 locks
Use the SIM card lock and the device lock to protect your SIM
card and your P800 from unauthorized use. Use the key lock to
prevent the keys from being accidentally pressed.
Note You can usually make an emergency call without
unlocking the P800.
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
which you receive from your service provider.
You can choose to have the SIM card locked every time you turn
the P800 on, or to have the SIM card unlocked.
Your PIN (Personal Identification Number) code consists of four
to eight digits. If you activate the SIM card lock, the P800 will
ask for the PIN code when you start it.
To activate the SIM card lock
1. Select Phone > Edit > Preferences > Locks
2. Select a lock option.
3. Select Done .
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 unblock 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.
