Download the following latest version of WhatsApp Messenger and enjoy free voice calling. WhatsApp’s new update brings voice calling feature to all Android users. Currently, to activate voice calling in the messaging app, users had to receive a call from someone who already had the calling feature.
A user has posted a screen shot on PhoneArena that shows the voice calling feature. The images show a third new option titled ‘Calls’ along with Chats and Contacts tabs. Users can make calls simply by tapping on the Call icon at the top of the screen to all users in the WhatsApp contact list. The update is being rolled out slowly and users may receive it in a few days. If you are unable to update to v2.12.19 via the Play Store, you can try downloading the app directly from WhatsApp site
