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.
