9.Network (Menu 5)
The menu options you see in your phone are based on your service provider’s network.
The network determines which options actually appear in the phone’s menu. Check with
your service provider for more information.
The
Network
menu allows you to customize the way your phone chooses a network in
which to operate while you are within or outside of your primary or home system. Your
phone is set to search for the most cost-effective network. If your phone can’t find a
preferred network, it selects a network automatically based on the option you choose in
the
Network
menu.
