Rebtel blackberry app is hoping to gain some ground on Skype in the voip market. The voip app now allows Rebtel BlackBerry users to make free international phone calls to other Rebtel users on BlackBerry and Android apps.

Back in June, Rebtel launched its free international calling for Android phones. This app works in the same way and has expanded to the BlackBerry phones. The rebtel voip app runs in the background and intercepts an international call placed to another Rebtel user. The user is still required to have sign up for carrier minutes for the call however the international part of the call is free. The best part is that it doesn’t require a WiFi connection. This facility works for the 50 countries that Rebtel supports.

This is in addition to Rebtel’s existing plan for cheap calls between international users, which involves Rebtel creating a local number for a user to call when they call a contact in a foreign country. There’s a way to make those calls free too, by one person hanging up and calling their friend back. The new BlackBerry app should greatly expand the number of people who can take advantage of the simpler way of making international calls for free through the Rebtel app. Rebtel also launched an iPhone app in 2009, but the free international calling feature won’t come to the iPhone until this spring.

This is all part of Rebtel’s larger goal to become a VoIP challenger to Skype. The company, which already bills itself as the world’s largest independent mobile VoIP company, claims that it now has more than 9 million callers, and more than one billion minutes of international calls logged. Rebtel’s revenue more than doubled in 2010 to about $40 million and is projected to hit $75 million this year. Those numbers still put it far behind Skype, which this week hit a new record of up to 27 million users online at any moment and recorded 6.4 billion minutes of calls to landlines and mobiles in the first half of 2010. But as Rebtel matures and rides the growth of smartphones, it should be a solid No. 2 in voice calls; though as Skype is showing, the game is moving to mobile video as well, something Rebtel has no answer for yet.

If you’re familiar with the ins and outs of the Rebtel service you probably know that Rebtel have a feature called Free Calls. What it does is to allow you to make free international phone calls to any friend or family member living in either one of the 50 countries where Rebtel is available.

However, Free Calls on the Rebtel service is limited to your friends living in these specific countries. Hence Rebtel has a Tell Friends feature.
