If rumors are to be believed, the popular messaging service WhatsApp is all geared up to launch a free voice calling feature for the 600 million active users that it has. Though there isn't any official report that has come, there have been some changes in the interface that suggest the upcoming feature.
"The leaked images of the upcoming user interface show that the app has been enabled with other language translations which will be displayed at the time a person receives a call via WhatsApp," says a report on thefusejoplin.com.
Ever since Facebook has acquired WhatsApp, the messaging service has seen a 15% rise in its traffic. This would also be the perfect time for Facebook.
