Guide to enable voice call on WhatsApp with Android phone. XDA

WhatsApp messenger, the cross-platform mobile messaging app that allows exchanging messages for free, now seems to be offering the voice calling feature. A redditor has recently confirmed the roll-out of this feature.

However, the feature is in the beta version and is not yet ready for a public release. XDA member, shashankshetty has shared an easy guide using which you can enable the calling feature on WhatsApp. But you need to have a rooted Android device.

The member also advises that, "You need someone with the calling feature to call you for you to get the feature enabled, it's like an invite."

Head over to the following guide if you want to get started with the calling feature on WhatsApp.

Requirements

  • Root access
  • WhatsApp version 2.11.508 or higher. You can also use WhatsApp.apk from the following download link.
