Want to save? Check out our list of the best free calling apps

Our Android smartphones have more and more features and possibilities, including making free internet phone calls or cheaper prices. It is true that we do not always have WiFi available and that data packets can be more expensive than calling, however, to talk to friends abroad or in other states, these apps are the best in the Play Store at the moment.

Take a shortcut

Google Duo – Uneconomical and below average quality

One of the great advantages of the Duo over the competition is that the application has few functions and a minimalist user interface. Despite Google's promise that the Duo works on good and bad connections, the app's experience on problem connections is awful. And that is really frustrating. Because the service is recent, Big G should improve it in future updates.

The data plan consumption per connection is really high. Using the 4G connection, in a conversation of just under five minutes, 161MB of the plan was consumed. This is without the "mobile data usage limit" enabled.
