If you’ve been impatiently waiting for an invite to try out the new WhatsApp calling feature, you’ll be glad to know someone finally flipped the switch for everybody.
The only catch is you need to make sure you have the most recent version of the app installed

Once you have this new feature enabled, you’ll see three new tabs in the interface: one for calls, chats, and contacts. The feature set is pretty straightforward, but at least you can switch to speakerphone and mute your microphone if needed during a call.
