Here’s a tech/web recommendation/review. I’m traveling in the boonies, meaning outside of the USA without broadband or cheap telephone service. In fact locally it costs about $1 per minute to call back to the states. Enter Skype. If you’ve used it before, you’ll know it has terrific sound quality. What really blew me away is its performance on dial-up. In the middle of nowhere, as long as you have a 56k internet connection, you can call from your laptop to any phone in the world for pennies. This is nothing new, as ICQ has a similar service with IDT’s Net2phone, which I tried before as well. Skype wins hands down however. The sound quality is better than a regular phone, but more importantly, there is no lag or dropped sounds.
If you’re traveling with a laptop, and need a cheap way to call home, get Skype.
