Introduction

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

a4- 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.

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.

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.

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.
