try using the commands from this thread but change them to suit your hardware. i dont think the drivers will work for you so disregard that part i guess.

@LTE-Card Did you check the Sierra Wireless web site at all? Because the Sierra Wireless EM74xx AT Command Reference manual is available here... at sierrawireless.com! Simple no-brainer account registration required.

 

Also available here, again with account registration though through a more complicated process it would seem.

For the rest, I assume you know that you have to define the APN parameters for the connection you want to initiate; parameters depend on your service provider/Telco.

 

You may also want to use the standard keyboard shortcuts to take screenshots rather than pictures with a cellphone...
