What do I need to use 3G card

[Guest furby]

So, I've got 2 of these 3G data cards http://www.expansys.com/p.aspx?partner=modaco&i=141035

*Long name warning * Novatel Wireless Merlin XU870 3G HSDPA 3.6/7.2 Mbps ExpressCard

And well, they've been sitting around doing nothing so I thought I would actually use it. I stuck my vodafone sim in and did some searching on the internet for the settings (unsuccessfully) and so can't get it to connect.

Is it possible to just put in the settings and pay for the data pay as you go? I'm on a corporate tariff so the data fairly cheap.

Or if not is it possible to get Sim-only 3G payasyou go? I'd rather not enter into a contract if I can get away with it.

Thanks

Teach me to ask before doing some proper research. Loaded up the Vodafone Mobile Connect and it worked first time on my Mac and windows machine. Weee
