AirCard Data Card User Guide
6 2131233
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 Data Card before you use it. (Depending on your service provider, the
SIM card may already be inserted.)
When establishing a connection, your AirCard Data Card 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.
• Account provisions — Your account may restrict your usage to certain
networks or limit the amount of time you can use the network.
• Frequency band — You cannot connect to networks operating in bands not
supported by your AirCard Data Card, regardless of roaming agreements or
account provisions.
Most service providers have coverage maps on their web sites.
