Select Menu
Network
The network menu allows you to customise the roam call ringing
tone, and the way your device chooses a network in which to
operate while you are within or outside of your primary or home
system. Your device is set to search for the most effective network.
If your device cannot find a preferred network, it selects a network
automatically based on the option you choose in the network menu.
The menu options you see in your device are based on your service
provider's network. The network determines which options
actually appear in the device menu. For more information, check
with your service provider.
