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 a wireline carrier. The
other cellular service provider is a radio common
carrier, referred to as a non-wireline carrier.
Your Cellular Service Operator will provide
information concerning specific features,
procedures, and coverage in your particular area.
The area within which the telephone operates is
defined by your cellular service provider. Since this
is a radio system, no exact boundaries (as on a
map) can be drawn. The red

indicator will be displayed if you are beyond range
of a service area. There may be locations within
your area, such as tunnels and underground parking
facilities, where the phone may act as if it were
beyond range.
If you are called while in a location the system
determines is inadequate for high quality service,
you may hear a series of beeps to inform you of
the call attempt. The caller will receive the
recorded ‘not in service’ message,
