Access codes

The following section describes various security codes used on your phone.

PIN1 code (4 to 8 digits)

The PIN1 (Personal Identification Number) code protects your SIM card against unauthorized use. The PIN1 code is usually supplied with the SIM card. If you input the incorrect PIN1 code entry three times in a row, the PIN1 code will be blocked. If the PIN1 code is blocked, you need the PUK 1 code to unblock before you can use the SIM card again. See information on the PUK1 code.

PIN2 code (4 to 8 digits)

The PIN2 code, supplied with some SIM cards, is required to access some functions, such as call cost counters. Contact your carrier for information.

Lock code

The lock code can be used to lock the phone and keypad to avoid unauthorized use.

NOTE The factory setting for the lock code is 1234. To avoid unauthorized use of your phone, change the lock code. Keep the new code secret and in a safe place separate from your phone.

PUK1 and PUK2 codes (8 digits)

The PUK1 (Personal Unblocking Key) code is required to change a blocked PIN1 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.

NOTE You can change the following codes: lock code, PIN1 code, and PIN2 code. These codes can include numbers from 0 to

9 only. The [#] key works as the [o] function.

Avoid using access codes similar to emergency numbers such as 112, to prevent accidental dialing of an emergency number.

Network Barring Password (4 digits)

The N/W password is required when you use the N/W Barring function. Your service provider will provide the N/W password to you when you subscribe to this function.

You can change this password using the Call barring function.
