The Cellular System
There are generally two types of cellular systems
serving any metropolitan area. One of these will
most likely be operated by the telephone
company that provides telephone service to your
community, generally referred to as the
carrier. The other Cellular Service Provider is a
radio common carrier, referred to as a
carrier.
Your Cellular Service Provider you choose will
define your “home” system. They will provide
information concerning specific features,
procedures and coverage in your area.
Service Area
The area within which the phone operates is
defined by your Cellular Service Provider. Since
cellular is a radio system, no exact boundaries
(as on a map) can be drawn. The “NO SVC” (No
Service) indicator
in
your display will light when
you are beyond the range of a service area. There
may be locations within your area, such as
tunnels and underground parking facilities,
where
the unit
may act as if it were beyond range.
Roaming
The term “roaming” applies to the use of cellular
telephones within systems other than those
designated as their “home” system. The “ROAM”
indicator comes on whenever the unit comes
within range of a visited system. As your phone
begins to roam, it seeks service in accordance to
the conditions you have selected.

A steady on “ROAM” indicator signals that your
phone is accessing a home type system, while a
flashing “ROAM” indicator signals that your
phone is attempting a connection through a
home type system.
Contact your Cellular Service Provider, or that of
the visited system, for information on dialing and
billing procedures.
To use alternate long distance services when
roaming, be certain to dial the appropriate area
code and local number to access the alternate
carrier in the visited area.
