Rebtel has acquired Free World Dialing, an award-winning consumer calling service from Talkster. Talkster's Free World Dialing customers will now have access to Rebtel's Free Calls solution, the only VoIP service offering unlimited free international mobile calls between 51 countries.

Launched in October 2007 at the CTIA Wireless Entertainment and I.T. exposition, Talkster's Free World Dialing service was immediately hailed as a breakthrough new service, winning "Best In Show." Since then Free World Dialing continued to win widespread recognition along with a number of industry awards, including Mobile Star's Best Consumer VoIP App and Communications Solutions Product of the Year. Rebtel has acquired the full rights to the Free World Dialing service and its customers for an undisclosed sum. Under the agreement, Rebtel now carries all of Talkster's international calls.

In addition to Rebtel's Free Calls solution, former Talkster customers have access to other services from Rebtel, which make it possible to use any phone in 51 countries to call anywhere in the world for free or for just pennies per minute. The acquisition also allows Talkster customers to use Rebtel Computer Calls to make free or super-cheap calls from any country to anywhere in the world, as well as Rebtel SMS for low-cost international text messaging.

Rebtel is growing rapidly and now serves more than 4 million registered customers worldwide, and adds more than 100,000 new users each month. Revenue in 2009 was close to $20 million and grew 75% versus 2008. Rebtel expects to grow at a similar rate in 2010.

The acquisition of Talkster's Free World Dialing comes just months after Rebtel's similar acquisition of the Gorilla Mobile service, a U.S.-based VoIP company that provided low-cost calling primarily to Asia.
