ROAMING

Each cellular service area can have two cellular service
suppliers called carriers. One carrier operates the "non-
wireline'' or "A'' system and the other carrier operates the
"wireline'' or "B'' system. Your phone is designed to work
with either or both carriers.
The system priority feature allows you to program your phone
for optimum operation when in your home service area or
when away from your home area (this is called roaming).
When you buy your phone, you may register (receive a
phone number) with either or both of your local carriers.
Contact the office of your home cellular phone company
for information about the roaming agreements they have
with other cellular phone companies.
In some areas, roaming telephones are automatically
recognized by the cellular system's computer. In other
areas, you must contact the cellular phone operator before
it can recognize your phone. The company needs to know
your telephone number, your phone's ESN (electronic seri-
al number), and how you plan to pay for your calls. There is
usually an additional charge for roaming calls.
Note: The mechanical SN# for your mobile phone is located
in the battery compartment of the phone. Add the manufac-
turers' prefix to the 8 digit mechanical SN# to get ESN.
