Introducing the AirCard 800 Series Modems
Your ability to obtain service depends on these factors:
GSM network coverage—You must be within the 
coverage area of a GSM network in order to use the 
AirCard modem. 
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 
modem, regardless of roaming agreements or account 
provisions.
Most service providers have coverage maps on their web sites.
