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
icons.
