Talkster's Free World Dialing Service tears down the global calling barriers, and more importantly, works as promised on any cell with any carrier. Turning long-distance and international calls into local ones, Talkster launched its new ad-supported service at the show. The service is simple to use: You visit the Talkster Web site from a PC or cell phone browser and enter your number and the number of the friend you'd like to call. After you connect to the local number, you'll need to listen to a ten-second commercial before you can talk for free. Even though you have to maintain your carrier's local calling plan, Talkster Free World Dialing is an easy, cheap way to get your international calling fix--without having to carry around a VoIP phone or hand over credit card information.
