Roaming Indicators
When the phone begins roaming, it beeps, displays
ROAMING
, and lights the roaming indicator ( ). For a
description of the two states of the roaming indicator,
see “The Display and Connectors” chapter. Some
cellular systems can recognize a roaming phone
automatically. In other systems, you must contact the
cellular operator before the system can recognize the
phone. You will need to give your phone number, your
phone’s ESN (electronic serial number), and how you
plan to pay for your calls. There is usually an additional
charge for roaming calls.
Note: The ESN for your cellular phone is printed under
the battery pack on the back of the phone.

The cellular operator programs your phone with
software called a Number Assignment Module (NAM)
when you register for service. You can register your
phone with up to 3 cellular systems, each giving your
phone a different NAM, which contains unique data for
you such as your phone number, home service area,
and A-key.
Only one NAM is in effect at a time. When you select a
phone number, you are also selecting which system
you are using as your home system. The first phone
number displayed with this menu is the phone number
in use.
Note: You need at least one active number to make
calls. You cannot change from one NAM to another
during a call.
