WhatsApp has now made the group calling feature available on the platform.
WhatsApp said they have over 450 million unique users per day, who make over 2 billion minutes of calls daily.
The group calling feature is currently rolling out on the iPhone and Android versions of WhatsApp.
How it works:
1. Start a call with a contact.
2. Click the “add participants” button shown in the top right corner of the chat window.
3. Up to four people may participate in a group call.
Facebook said group calls are encrypted end-to-end, and are designed to work on low-bandwidth networks.
