4. Protecting the SIM Card and the Phone
The SIM card contains a computer chip that
holds information specific to your subscription
and the services that you have requested from
your network operator.
Card Lock
The card lock protects your SIM card.
When you purchase your SIM card, you obtain
a 4- to 8-digit PIN code. PIN stands for Person-
al Identification Number.
Each time you turn the phone on, you have to
enter the PIN code and then press
#
.
If the wrong PIN is entered three times in
succession, the SIM card is blocked. If this
happens, refer to chapter 28. Problems You
Can Solve.
If your SIM card allows it, you may turn off the
card lock. This is described in chapter 11. The
ACCESS Menu.
The PIN can be changed
If you do not like the original PIN, you may
change it to a code you find easy to remember.
How to change the PIN code is described in
chapter 11. The ACCESS Menu.
Should you forget your PIN, you may choose a
new PIN by entering a sequence of charac-
ters, including your personal unblocking key
(PUK) as described in chapter 28. Problems
You Can Solve. Refer to the section entitled
Alternative method to unblock the SIM card.
PIN2
Some services require that you enter a second
PIN code, the PIN2 code. Also the second PIN
code can be changed in the Access menu.
Phone Lock
The phone lock protects the phone against
unauthorised use of the phone in the event of a
theft.
The phone lock is not activated when you
purchase the phone. You should, however,
activate it as soon as possible.
The factory-programmed security code
should be changed
The phone is factory-programmed with a 4-digit
security code of 0000. To improve security, you
should change this to any 4- to 8-digit personal-
ised code.
You should choose your security code carefully.
You can, for example, use the same code as
your PIN, or another code that you find easy to
remember.
How to change the security code is described in
chapter 11. The ACCESS Menu.
Should you forget your security code, you
must contact an authorised dealer.
Two levels of locking
There are two levels of locking the phone:
● Full Lock
● Autolock
When the Full Lock is activated, the message
Phone locked is displayed briefly, followed by
the prompt Enter lock code, each time the
phone is turned on. The user then has to enter
the security code, followed by
#
, to be able to
use the phone.
When the Autolock is activated, the message
Phone locked and the prompt Enter lock code
will not appear until a different SIM card is
inserted in the phone. After the security code
has been entered correctly, the phone can be
used with new SIM card. Not until the original
or a different SIM card is inserted in the
phone, will the user again be asked to enter the
security code.
How to lock the phone is described in chapter
11. The ACCESS Menu.
Keypad Lock
You can lock the keypad so that unintentional
key action has no effect if the phone is turned
on when you are carrying it in a pocket or a
handbag. This function is useful if you have a
phone without keypad protect flip.
How to lock and unlock the keypad is described
in chapter 15. The KEYLOCK Menu.
