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.
