Note: Only administrator-level users can install software. However, when the
installation is complete, all users will have the possibility to access the
Internet with a USB modem key.
You can connect an optional 3G USB modem key to your unit to have a
wireless access to the Internet.
When you receive your Sierra Wireless 319U modem key, it contains no
Subscriber Identity Module (SIM) card. This means that you will need to:

Purchase a compatible and unlocked SIM card from a provider offering
3G services. If you need more information on the 3G coverage in your
area, contact your regional sales representative.

Have the card activated (you must subscribe to a package of mobile
services).

Insert the card in the modem key.
The very first time you connect a USB modem key to your unit, the AirCard
Watcher application will be installed automatically on your unit. You will
use this application to establish a connection with the mobile network
whenever you want to work with your USB modem key. You only need to
install this application once.

Always turn your unit on before connecting the USB modem key to
it. Otherwise, the USB modem may not be detected properly.
