I'm sure telia has such a thing, maybe he's living in a rural area, or maybe he's been a victim of terrible advertising.
"Mobile broadband" like what it seems like he's using uses a phone-like device (except there's no display or buttons on it or anything) that you plug into an USB port, and you usually install some custom software to connect to the ISP.

Do you have good cell coverage where you use your computer? Can you call people with your cell phone without problems?
