Access codes
You can use the access codes described in this section to avoid unauthorised use of your phone. The access codes (except PUK and PUK2 codes) can be changed by using the Change codes feature
PIN code (4 to 8 digits)
The PIN (Personal Identification Number) code protects your SIM card against unauthorised use. The PIN code is usually supplied with the SIM card. When the PIN code request is set to On, your phone will request the PIN code every time the phone is switched on. When the PIN code request is set to Off, your phone connects to the network directly without the PIN code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required to access functions such as Advice of Call Charge and Fixed Dial Number. These functions are only available if supported by your SIM card.
PUK code (4 to 8 digits)
The PUK (PIN Unblocking Key) code is required to change a blocked PIN code. The PUK code may be supplied with the SIM card. If not, contact your
network operator for the code. If you lose the code, also contact your network operator.
PUK2 code (4 to 8 digits)
The PUK2 code, supplied with some SIM cards, is required to change a blocked PIN2 code. If you lose the code, also contact your network operator.
Security code (4 to 8 digits)
The security code protects the unauthorised use of your phone. The default security code is set to ‘0000’ and the security code is required to delete all phone entries and to activate the Reset Settings menu. Also, the security code is required to enable or disable the phone lock function to prevent unauthorised use of the phone. The security code default setting can be modified from the Security Settings menu.
Network password
The Network password is required when you use the Call Barring function. You obtain the password from your network operator when you subscribe to this function. See page 50 for further details.
