About selecting a system
The System menu (
Menu
5) allows you to customize the
way your phone chooses a system in which to operate
while you are “roaming” (using your phone outside of
your primary or “home” system). Your choice of a system
affects the type and amount of charges you incur. By
default, your phone is set to automatically search for the
most cost-effective system while roaming. If your phone
can’t find a preferred system, it uses a system based on
the option you choose in the System menu.
Note: Before selecting an item in the System menu, contact
your service provider to find out how your selection
will affect your service charges.
Roaming
Roaming is the condition of using your phone outside of
its home area. While roaming, another service provider’s
system handles your call, so the service rate for the call is
usually greater than the rate for calls made within your
home area. While roaming, the word
Roaming
and the
roaming indicator ( ) appear on the start screen.
Note: In some systems, you may need to have a roaming
agreement in order to place a call. If no roaming
agreement has been arranged, a network operator
may interrupt and request information on how you
intend to pay for the call.
Service Types
In each wireless service area there are usually two service
providers referred to as type
A
and type
B
. When you first
set up your wireless service account, your service provider
will inform you of which system you will be using (usually
type
B
). This is your home system. The other system (for
example, type
A
) is known as a non home-type system.
