Chapter 18 Access codes
PIN code - This code protects your SIM card against unauthorised
use. The PIN code (4 - 8 digits) is usually supplied with the SIM
card.
PIN2 code - This code (4 - 8 digits) is supplied with some SIM
cards, and is required to access some functions in your mobile
terminal.
If you forget an access code, contact the network service provider
whose SIM card is in your mobile terminal. After three consecutive
incorrect PIN or PIN2 code entries, the code is blocked, and you
need the PUK code to unblock it.
PUK code and PUK2 code - These codes (8 digits) are required to
change a blocked PIN code or PIN2 code, respectively. If the codes
are not supplied with the SIM card, contact the network service
provider whose SIM card is in your mobile terminal.
IMEI number - This number (15 or 17 digits) is used to identify
valid devices in the GSM network. Devices that are, for example,
stolen, can be blocked from accessing the network. To view the
IMEI number for your mobile terminal, in the home screen, enter
*#06#.
Lock code (also known as security code) - The lock code helps you
to protect your mobile terminal against unauthorised use. You can
create and change the code, and set the mobile terminal to request
the code. Keep the new code secret and in a safe place separate
from your mobile terminal. If you forget the code and your device
is locked, your mobile terminal will require service. Additional
charges may apply, and all the personal data in your mobile
terminal may be deleted.
