Each AirCard PC Card has been provisioned at the factory for
use with a particular service provider. This sets the AirCard
PC Card to use particular radio channels and enables services
specific for that provider.
The process of setting up your account is called activation.
Activation involves action by the service provider and configu‐

The CDMA wireless network

This is the worldwide infrastructure providing the radio
coverage that allows you to stay connected. Made up of radio
towers and a variety of network switches, routers, and servers,
the network is an interconnection of many service providers.
.
There are CDMA networks that operate in the frequency bands
supported by the AirCard PC Card throughout North America
and parts of Latin America, Asia, and New Zealand. However,
each service provider operates a network that covers a limited
geographical area within the overall CDMA coverage area.
Most service providers have "roaming" agreements with other
service providers, so that they can offer service outside of the
coverage area of their own networks. For example, assuming
you live in Vancouver and travel frequently to Seattle, you can
obtain an account with a Vancouver service provider that has a
roaming agreement with a service provider in Seattle. You
would then have local service in Vancouver, and roaming
service in Seattle.
