Why is that? Are the electrical characteristics of the phone line
actually that different from US lines?

I worked for a modem company for a few years, though I mostly was

other countries was always a giant pain, but the problems were almost
entirely regulatory hurdles, and not so much that the modem wouldn't
actually work.
