You may heard about WhatsApp’s live voice calling for Android operating system. Now this feature has come in new version of Whatsapp which is released yesterday. But you need a friends help to activate this feature in your phone. First of all you need to install Whatsapp’s lastest version, after that ou’ll have to ask a user who has the feature to call you.
Once you received a call, you need to restart your app then you should now see a new screen with three featurs, including one for live calls.
You can then call any of your WhatsApp contacts over VoIP through the app. People having an older version wouldn’t get this feature and this isn’t conform that company will charge on calling or not.
Please keep in touch for more details.
