Access Code
The following section describes various security codes.
PIN code (4 to 8 digits)
The PIN (Personal Identification Number) code protects your SIM card against the unauthorized use. The PIN code is usually supplied with the SIM card. If you input the incorrect PIN code entry for three times in a row, the PIN code will be blocked. If the PIN code is blocked, you need to unblock the PIN code before you can use the SIM card again. See the information on the PUK code.
PIN2 code (4 to 8 digits)
The PIN2 code, supplied with some SIM cards, is required to access to some functions, such as call cost counters.
Lock code (4 to 8digits)
The lock code can be used to lock the handset and keypad to avoid unauthorized use.
NOTE
The factory setting for the lock code is 1234. To avoid unauthorized use of your handset, change the lock code. Keep the new code secret and in a safe place separate from your handset.
Access Code
PUK and PUK2 codes (8 digits)
The PUK (Personal Unblocking Key) code is required to change a blocked PIN code. The PUK2 code is required to change a blocked PIN2 code. If the codes are not supplied with the SIM card, contact the operator whose SIM card is in your phone for the codes.
You can change the following codes: Lock code, PIN code, and PIN2 code. These codes can include the numbers from 0 to 9 only.
NOTE
Avoid using access codes similar to the emergency numbers, such as 112, to prevent accidental dialing of the emergency number.
Call Barring Password (4 digits)
The call barring password is required when you use the Call Barring function. You obtain the password from your service provider when you subscribe to this function.
You can change this password using the Call Barring menu option. For further details, see menu 6.7.6.
