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, 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 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.
