■ Network services
To use the phone you must have a service from a wireless service provider. Many
of the features in this device depend on features in the wireless network to function.
These network services may not be available on all networks or you may have to
make specific arrangements with your service provider before you can utilize network
services. Your service provider may need to give you additional instructions for their
use 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.
■ Configuration settings service
To use some of the network services, such as mobile Internet services, MMS, or
synchronization, your phone needs the correct configuration settings. You may
receive the settings directly as a configuration message, and you need to save the
settings on your phone. The service provider may provide a PIN that is needed to
save the settings. For more information on the availability of the settings, contact
your network operator, service provider, nearest authorized Nokia dealer or visit
the support area on the Nokia Web site, www.nokiausa.com/support.
When you receive a configuration message, Configuration settings received is
displayed. To view the received settings, select Show.
To save the received settings, select Save. If the device asks Enter settings' PIN:,
enter the PIN-code for settings, and select OK. Select whether you want these
settings as the default. For availability of the PIN code, contact the service
provider that supplies the settings.
To discard the received settings, select Discard.
To view and edit the settings, see "Configuration," p. 37.
