Security code (5 to 10 digits)

The security code protects your phone against unauthorized use. The pre-set code is 12345. Change the code, and keep the new code secret and in a safe place separate from your phone. To change the code, and to set the phone to request the code, see Security settings.

If you key in an incorrect security code five times in succession, the phone ignores further entries of the code. Wait for 5 minutes and key in the code again.

PIN and PIN2 codes (4 to 8 digits), Module PIN and Signing PIN

• The PIN (Personal Identification Number) code protects your SIM card against unauthorized use. The PIN code is usually supplied with the SIM card. Set the phone to request the PIN code each time the phone is switched on, see Security settings.
  
• The PIN2 code may be supplied with the SIM card and is required to access some functions, such as call counters.
  
• The module PIN is required to access the information in the security module. See Security module in the printed Nokia 6230 User’s Guide. The module PIN is supplied with the SIM card if the SIM card has a security module in it.
  
• The signing PIN is required for the digital signature. See Digital signature in the printed Nokia 6230 User Guide. The signing PIN is supplied with the SIM card if the SIM card has a security module in it.

If you key in an incorrect PIN code three times in succession, the phone may display SIM blocked or PIN code blocked, for example, and you may be required to enter the PUK 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 your local service provider for the codes.

Barring password (4 digits)

The barring password is required when using the Call barring service, see Security settings. You can obtain the password from your service provider.

Wallet code (4 to 10 digits)

The wallet code is required to access the wallet services. If you key in an incorrect wallet code three times in succession, the wallet application is blocked for five minutes. Next three incorrect entries of the code will duplicate the time. For further information, see the printed Nokia 6230 User’s Guide.
