When I was on dial-up, AOL allowed me to access from any telephone number. Their site also gives several alternative AOL access numbers in most areas of the world, so you only pay a local phone call charge.
There's lots of "love 'em or hate 'em" threads about AOL on this forum. I've read that it takes over your PC, but this hasn't happend for me, I think because I didn't permit it to "become my default browser" during installation. And, in my experience, removing it is as simple as deleting the AOL folder.
