Network services
To use the device you must have service from a wireless service provider. Some
features are not available on all networks; other features may require that you make
specific arrangements with your service provider to use them. Network services
involve transmission of data. Check with your service provider for details about fees
in your home network and when roaming on other networks. Your service provider
can explain what charges will apply.
Your service provider may have requested that certain features be disabled or not
activated in your device. If so, these features will not appear on your device menu.
Your device may also have customized items such as menu names, menu order, and
Access codes
To set how your phone uses the access codes and security settings, select 
Access codes
The security code helps to protect your phone against unauthorised use. The
preset code is 12345. You can change the code and set the phone to request
the code. Some operations require the security code regardless of the settings,
for example if you want to restore the factory settings. Keep the code secret
and in a safe place separate from your phone. If you forget the code and your
phone is locked, your phone will require service and additional charges may
apply. For more information, contact a Nokia Care point or your phone dealer.
The PIN (UPIN) code, supplied with the SIM (USIM) card, helps to protect the card
against unauthorised use.
The PIN2 (UPIN2) code, supplied with some SIM (USIM) cards, is required to
access certain services.
PUK (UPUK) and PUK2 (UPUK2) codes may be supplied with the SIM (USIM) card.
If you enter the PIN code incorrectly three times in succession, you are asked
for the PUK code. If the codes are not supplied, contact your service provider.
The barring password is required when using the call barring service to restrict
calls to and from your phone (network service).
