Your account and coverage area
Note: If you purchased the
AirCard from a GSM service
provider, you may already have
an account. Otherwise, your
retailer should be able to provide
you with the names of
companies that provide this
service.
Companies that operate GSM networks and provide access to
those networks are called service providers. You must have an
account with a GSM service provider that offers GPRS service
to use the AirCard.
When you obtain your account, you will be given a SIM card,
otherwise called a “smart card” or “smart chip”. (Depending
on how you purchased your AirCard, you may already have
an account, and your SIM card may have been included in
your package.) The SIM card contains account information
and must be inserted in the AirCard anytime you use it.
Before you can use the AirCard, you must install the AirCard
software and ensure that your AirCard is configured to use
your account. Instructions on completing these steps are
provided in the chapters that follow.
Once installed and configured, you can connect to the Internet
with the AirCard in any area in which you can obtain GPRS
service. Your ability to obtain GPRS service depends on these
factors:
