Introducing the AirCard® 595U USB modem
A CDMA service provider account
Companies that operate CDMA networks and provide access to these networks are called service providers. To use the AirCard USB modem, you must have an account with a CDMA service provider.
Each service provider has its own pricing options. There may be flat rate accounts, which provide you a maximum number of minutes of network usage for a fixed monthly fee. There may be accounts for which you are charged for network usage by the minute or by the amount of data transmitted.
Your account may include a variety of other services such as SMS messaging.
Each AirCard USB modem has been provisioned at the factory for use with a particular service provider. This sets the AirCard USB modem 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‐ ration of the AirCard USB modem.
The procedure to configure (activate) your AirCard USB modem is covered in “Activation” on page 20.
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 USB modem 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.
