Getting to know your P910a 37
Preliminary Layla850 P1B
SIM card lock
The SIM card lock protects your SIM card, not the P910a,
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 P910a 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 P910a 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.
Device lock
The device lock protects your P910a and the data in it against
unauthorized use.
If the device lock is set to
When SIM changed
, it means that the
P910a is not normally locked. However, if the SIM has been
changed, the P910a asks you to enter the code to unlock the
P910a before you can use it. This means that if someone steals
your P910a and puts another SIM card into it, they will not be
able to use it.
Note Your operator can block your SIM, if you report that your
phone has been stolen.
The device lock is not on when you buy your P910a. You can
change the device lock code to any four to eight digit personal
code.
The default device lock code is 0000.
