About the AirCard USB Modem
The Sierra Wireless AirCard
®
USB Modem enables you to connect to
the Internet, send and receive email, connect to a corporate network
or virtual private network (VPN), or view streaming video without the
need for a network cable.
The AirCard USB Modem connects to a Type A USB port on your
computer.
If the AirCard USB Modem is TRU-Install enabled, all the required
software is available on the modem. When you set up your AirCard
USB Modem, the software is installed on your computer. You do not
need an installation CD. (Depending on your service provider, your
modem may include an installation CD.)
The AirCard USB Modem has a built-in antenna and may have a slot
that accommodates a microSD

external memory card. Depending
on your service provider, a microSD card may be included in your
package, or you may need to purchase it separately.
Your account and coverage area
Note: If you purchased the
modem from a GSM
service provider, you may
already have an account
and a SIM card.
Otherwise, your retailer
should be able to give you
the names of companies
that provide these items.
You must have an account with a GSM service provider to use the
AirCard USB Modem. To use the AirCard USB Modem’s 3G
capability, your account must be with a service provider that offers 3G
service. (The AirCard USB Modem is backwards compatible with 2G
service.)
When you obtain your account, you are given a Subscriber Identity
Module (SIM) card containing account information. You must insert
the SIM card into the AirCard USB Modem before you use it.
(Depending on your service provider, the SIM card may already be
inserted.)
When establishing a connection, your AirCard USB Modem uses the
fastest available service. Your ability to obtain service depends on
these factors:
Note: The fee for service
is usually higher when you
are roaming (connected to
a network other than the
one belonging to your
service provider).
• Network coverage—You must be within the network coverage
area.
• Service provider—If you are within the coverage area of a
network that is not operated by your own service provider, you
can obtain service only if there is a roaming agreement between
your service provider and the network operator.
