Skype and similar services have brought the world free calls from computer to computer and cheap calls from computer to phone for those willing to download software and speak while staring at a computer screen.

Now a Swedish start-up called Rebtel is using the same technology, Voice Over Internet Protocol, to bring cheap international calls to cellphones.

It takes a few minutes to set up an account with Rebtel, and users must do it online at the company's Web site. But once done, the service can be used to call any country in the world from any mobile or fixed-line phone in 37 countries, including the United States, Japan and most of Europe.
