System selection
The System menu (Menu 5) allows you to modify how your
phone will work when you are outside of your primary or
“home” system. (Items on the System menu may differ
depending on your service provider.) How your phone will
handle being out of your home area can significantly affect
the types and amounts of additional charges you may incur.
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 (for example, type A). This is your home system.
The other system (for example, type B) is known as your
non-home system.
Roaming
Roaming is a term used to indicate that your phone is not in
its home area. While roaming, you are actually using another
service provider’s system. Calls made or received while roaming
are usually more expensive than calls made in your home area.

Roaming indicators
When your phone begins roaming, Roaming appears. If roaming
in a non-preferred system, the roaming indicator (
) also
appears.
System choices
Your phone will automatically try to use a preferred system.
If your phone fails to find a preferred system, then it will use
the selection you have chosen with this feature. Before you
select a system, contact your service provider to learn how
these changes may affect your phone bill. Items on the System
menu may differ depending on your service provider:
•
Automatic - Use the home system. If unavailable,
use a non-home system.
•
Automatic A - Use the home or preferred system.
If unavailable, use system A.
•
Automatic B - Use the home or preferred system.
If unavailable, use system B.
•
Home only or <service provider’s name> - Use only
the home system. If unavailable, No service appears.
•
Analog - Use the available analog network.
Note: If you turn your phone's power off then on, depending on
your service provider, the system may return to the default
selection.
Which system should you choose?
By default, your phone is set to automatically search for the
most cost-effective system when you are outside of your home
area. For example, if your home system is type A and you are
roaming, your phone will automatically try to use the local
home system (the type A system in your current location).
The type B system would be a non-home system.
However, in an area where no home or preferred systems are
available, use this menu to manually choose which system
your phone uses.

By setting your phone to use a home or preferred system, it’s
possible for you to receive discounted roaming charges. Check
with your service provider to maximize use of this feature.
In non-preferred systems, normal roaming charges are
determined by the host system. Your phone is designed to
select a system most favorable to you concerning the cost
of the call and reception quality.
Note: When roaming 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.
If you have more than one phone number
The currently-selected NAM in your phone determines which
system is your current home system. See “Choosing your phone
number (NAM selection)” on page 35 for more details.
Note: Powering the phone off then on will reset any manual
overrides for analog or non-preferred systems.
