WhatsApp finally adds voice calls for all Android users: How to Enable if You're An Indian User
Android users can finally make voice calls on WhatsApp, thanks to a quiet but major update. The feature has been teased for months, with the update hitting select users a few weeks ago.

Now, however, it seems it's available to all, with the latest version of WhatsApp offering a new, cleaner layout, with three tabs for Calls, Chats, and Contacts. As you'd expect, you simply click the Calls tab and select a contact to chart talking.

If you've still haven't got the WhatApp voice feature activated, then here's what you need to do. Firstly, download version 2.11.528 from the Play Store or version 2.11.531 from the WhatsApp website. Once you have the latest version, voice-calling ability can be activated by receiving a call from someone whose voice-calling is already activated.

The WhatsApp voice calling feature is available only for Android, and is expected to make its way to iOS users soon. At the Facebook F8 conference held recently, WhatsApp cofounder Brian Acton said that the messaging service is preparing to bring the voice calling feature to iOS users in the coming weeks.
