It didn't take long for Gizmo to start changing their bait and switch plan of "free calls to 60 countries". When I first saw the service they offered free calls to Brazil on both land-lines and mobile phones. As of 1 week ago, they started charging for mobile calls to Brazil. I wonder how long it will be until they re-sume charging for all call.
The free call approach to sign up users works well as long as your service is better than the competition. As of today, Skype client runs circles around the Gizmo client. The day Gizmo resumes charging for calls to land-lines is the day I unsubscribe from their service - unless they significantly improve their Mac client (and add video calling like their better known competitor).
