Rebtel With a Cause: Free Calling on the BlackBerry

Mobile Internet telephony firm Rebtel said on Friday that it is bringing its free international calling service to the BlackBerry. The service, which allows free international calls among more than 50 countries by routing the calls over the Internet, has been available for Android since last March. Rebtel also said it plans to add the free calling feature to the iPhone this spring.

“We are committed to bringing innovation into the oligopolistic marketplace to make international calls either free or super-cheap for our customers,” Rebtel CEO Andreas Bernstrom said in a statement. Rebtel’s app automatically notices when an international call is being made and routes the call over its VoIP service, as opposed to making a cellphone call.
