"Rebtel has Skype in its sights and is hoping a new update to its BlackBerry app will help it make up some ground on the VoIP leader. The app now allows Rebtel BlackBerry users to make free international phone calls to other Rebtel users on BlackBerry and Android apps," writes Giga Om's Ryan Kim.
"We wrote about Rebtel launching its free international calling on Android back in June. This works in the same way and expands it to BlackBerry devices. The app runs in the background and intercepts an international call placed to another Rebtel user. A user will still have to use their carrier minutes for the call, but the international part of the call is free, and it doesnt require a Wi-Fi connection. It works for the 50 countries Rebtel supports," Kim writes.
