To make a call on the WhatsApp mobile app, go to the contact you wish to call. In the top right-hand corner, you’ll see icons for phone and video. Tap on the one you want to use. If this is the first time you’re making such a call, your phone will ask permission to access and use your camera and microphone.
The call will then start ringing. You can switch between audio and video calling at any time by tapping the video and audio icons. You can also mute yourself using the microphone icon.
How to make a free international call on WhatsApp (desktop app)
First, we should clarify that this is for the desktop app, not the web app. WhatsApp Web does not provide a call feature.
On the desktop app, go to the contact you want to call. In the top right-hand corner, you’ll see phone and video icons. Click on the one you want to use. If this is the first time you’re using the call function, your computer will ask you for camera and microphone access.
Once you click either the phone icon or video icon, it will ring. Even if you chose the phone icon, you could easily switch to a video call by clicking the video icon on the far left. Clicking the microphone button will mute you.
