RebVoice is a free Android app developed by Finarea in the Social & Communication category. It offers users the ability to make calls over WiFi or 3G, and when there is no steady internet signal available, they can call through call-back or by using a local access number. With RebVoice, users can enjoy great tariffs to all destinations.

The app is easy to use, just download it, create an account, and call your friends. RebVoice boasts crystal clear audio and cheap international rates, making it an excellent option for those who want to save on their monthly phone bill. Additionally, contacts from your Android phone are fully accessible within the app. It is important to note that using RebVoice as a default dialer may interfere with dialing 911 emergency services.
