The following terms are explained as they are used in this manual.

Home network

This is the network you chose when you took out your cellular service
subscription.  Normally, this will be the network that serves your home
area.  When you switch it on, your phone automatically tries to register
with your home network (unless you are away from your home area or you
have specified an alternative network).

NAM

The Number Assignment Module contains your cellular subscription and
telephone number.  It is set by your dealer at the time of purchase.  You
can, if you wish, have two different NAMs (NAM1 and NAM2) one for personal
use and one for business use for example.  The two NAMs can be set at
different times by different dealers, and they can be linked to the same
network or to two separate networks.

Roaming

Roaming, when available, allows you to seek service from networks other
than your home network.  This option is unavailable in certain areas or
countries.  Your dealer may also program your phone to recognize 'family'
networks in other cities.  There are two types of family networks; sisters
and cousins.  Calls on sister networks are usually billed at the same rate
as calls on your home network.  Calls on cousin networks are usually
billed at a preferred rate.

Type A and Type B networks

There are often two different cellular companies each operating a network
in the same area.  One is called Type A, and the other is called Type B.
In certain areas, roaming agreements between cellular companies allow you
to alternate between Type A and Type B networks.  This enables you to take
advantage of different rates in different areas or to seek service from an
alternate type network if your home type networks are busy or not in
service.
