Network services
To use the phone you must have service
from a wireless service provider. Many of
the features require special network
features. These features are not available
on all networks; other networks may
require that you make specific
arrangements with your service provider
before you can use the network services.
Your service provider can give you
instructions and explain what charges will
apply. Some networks may have
limitations that affect how you can use
network services. For instance, some
networks may not support all language-
dependent characters and services.
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 a special
configuration such as changes in menu
names, menu order, and icons. Contact
your service provider for more
information.
Functions without a SIM card
Some functions of your phone may be

Organiser functions and games. Some
functions appear dimmed in the menus

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.
