Network services
To use the device 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.
