When establishing a connection, your AirCard USB Modem uses the fastest 
available service. Your ability to obtain service depends on these factors:

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 modem, regardless of roaming agreements or account 
provisions.

Most service providers have coverage maps on their web sites.

The AirCard USB Modem has a USB connector, slots for a SIM card, and (on 
some models) a microSD external storage card. LEDs on the front or side of the 
AirCard USB Modem provide status information.

The placement of card slots, connectors, and LEDs varies depending on your 
modem model.
