Just a Click and a Phone Call AwayNew VoIP sites let you make calls all over the globe for cheap.

A few years ago, cellular companies did us all a huge favor by charging the same for a call across the country as for a call across the street. It kicked the floor out from under long-distance rates long before VoIP savings arrived.

Now we cell phone users can show our gratitude by using a new breed of VoIP websites to sidestep one of the cellcos' few moneymakers: international calling charges. Services likeCordia,Globe Dialer,JaJah,PingoandRebtellet us hop onto the internet and overseas via our cell phones--typically for 2 to 25 cents a minute (plus any plan minutes used). Rates vary by country, but providers claim to save you up to 90 percent over the cellcos' international plans.
