Internet Access without an Access Point (e.g. Sat)

Hey guys,
If you have no access to an access point/wi-fi point/hot-spot or something that connects you to the internet.....How would you access the internet? Whilst on the move (e.g. in a train or something)
Would you use a satellite connection or something ? What are the costs ? What are the limitations? What kind of speed is it ?
I'm not asking because of my laptop or something...I'm just asking because I'm kinda curious about how people can get onto the web like that....?
Many Thanks Guys!
