Menu 7, System Selection
This selection can be significant to the amount of roaming
charges you pay.
What is Type A and Type B?
In each wireless service area there are usually two service
providers operating on public wireless systems. They are
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 should
use (e.g. type A). This is your home system. The other sys-
tem (e.g. type B) is known as a non-home type system.
For example, if your home system is
type A and you are roaming, the type
A system in that area is a hometype
system. The type B system would be
a non-home type system.
Roaming
Roaming is a term used to indicate that your phone is not in
its home area. Calls made or received while roaming are
usually more expensive than calls made in your home area.
By setting your phone to use a home-type or preferred
system, its 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 de-
termined 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.

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 in-
terrupt and request information on how you intend to pay
for the call.
Which system should you choose?
When roaming in an area where no home or preferred sys-
tems are available, you can manually choose which
system your phone uses.
System choices
Depending on which system is in use, your phone will dis-
play either the A or B indicator or no indicator in the top,
left hand corner of your display.
Your phone will automatically attempt calls using a preferred
system. If your phone fails to find a preferred system, then
it will use the selection you have chosen using Menu 7.

tem A unless a home or preferred system is available.
