The folks at 192.com have branched out and launched their own version of the GRIC global ISP roaming service called Net2Roam. According to the blurb it covers 17,000 dial up locations in over 150 countries. They call it pay as you go, but it does incorporate a service fee as well as access charges. Still it’s probably worth noting if you’re a traveller.
In any event it looks to be cheaper than the iPass based PDA Roaming service.
