P900 locks
Use the SIM card lock and the device lock to protect your SIM
card and your P900 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 P900.
SIM card lock
The SIM card lock protects your SIM card, not the P900, against
unauthorized use. It is unlocked by the PIN and PUK codes
which you receive from your service provider.
You can choose to have to unlock the SIM card every time you
turn the P900 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 P900 will
ask for the PIN code every time you turn it on. You unlock the
SIM card by entering the PIN code.
To activate the SIM card lock
1. Select
Control panel
> Device > Locks.
2. Select a lock option.
3. Select
Done
.
An error message informs you if a wrong PIN code has been
entered. Usually, the SIM card will be blocked after three wrong
attempts (the number of attempts is SIM-card dependent), 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.
PIN2
Some functions on the SIM card can be protected by a
secondary code feature. Some SIM cards do not have a PIN2
lock.
The PIN2 lock cannot be deactivated. The code can be changed
by a user who knows the old code.
