3G cards

[geebee1982]

A (now ex) friend gave me a Vodafone 3G card for my laptop. I know nothing about it except I can send texts and get internet access with it. What I'd like to know is how is it paid? Because I haven't paid a thing. Me and him are no longer speaking so I can't ask him and he wouldn't pay for it now that we're no longer friends. I'm all confused! Please help! :)

There should be a SIM in the 3G card and the number associated with that will get charged.
