I now have a dialup ISP to use when I travel next week. I just signed up for access-4-free, which was $5 to sign up with 10 free hours per month. Best of all, they don’t require any special software and it works great with Mac OS X (in fact they even have Mac OS X setup instructions, although it refers to 10.0).
I’ve been looking for a free or cheap dialup ISP since I switched to AT&T Broadband last month. Unlike BellSouth DSL, they don’t provide dialup to use when I travel or when the service is down (so far it hasn’t been down). This looks like my best choice.
