If cost is an issue, and you can overcome the one-time hardware costs, Mindspring/Earthlink Global Roaming is only 10 US cents a minute in 80 countries around the world. The times I have tried it, it has worked well. Also, Internet cafes are growing exponentially, and are usually not very expensive. A month ago in London, I got an hour of access, with USB and serial ports, for only a pound.
