Voice over IP is evolving with an excellent gem of an app called Sidecar, which is available for Android and iOS devices.
Call quality as you might expect is not better than that of you carrier by any means. On the other hand, it is very good for a Wi-Fi connection; in fact there is an option to increase the quality of the audio, which will use more data. Reviews for the application for Android have came together to form a solid 3.7, which says that although the app is good there is room for improvement.
Aside from calling, users can share video, short messages, and more.
Bottom line: This app is a must have and it really shows the future that is in the palm of technology’s hand. Sidecar will only get better; be that early adopter.
