Phone calls and SMS privacy are now possible with Signal. What is 'Signal'? "Signal has been designed for the mobile environment from the ground up. Messages and incoming calls are fully asynchronous; push notifications to let you know when new messages have arrived, so they’ll be waiting for you if the app is in the background, your battery dies, or you temporarily lose service." - WhisperSystems
It is believed that the Government of Mauritius and other government entities around the world have been tapping into phone lines since a while and some years back this issue has also been revealed on Mauritian newspapers. So, how do you get away from these entities trying to peak their noes into your private life? The ultimate answer is "Signal" which has been developed by the Open Whisper Systems Team.

"I am regularly impressed with the thought and care put into both the security and the usability of this app. It's my first choice for an encrypted conversation." - Bruce Schneier, internationally renowned security technologist.
The signal is freely available and compatible for almost all Android devices as well as Apple mobile phones. It supports SMS and voice calls encryption even if you are on a 3G/4G network. However, you need to assure yourself that all parties engaged in a conversation are using Signal to be secure on all sides.
You cannot assure yourself to be secure if encrypted communication is one-sided.
