WhatsApp video calling lets you place a video call to anyone using WhatsApp. Video calling is only available to users who are on iOS 8.0+. If your system OS is not supported, video calling will not be available to you.
Note: Make sure you have a strong network connection when placing or receiving video calls. A poor or improperly configured connection may result in poor video and audio quality. If you are connected to Wi-Fi, your video call quality is dependent on your wireless network signal and your network data speed.
To make a WhatsApp video call, simply open the chat with the person you want to call and tap Video Call in the top right corner.
When you receive a video call, you will see an incoming WhatsApp video call screen. If your phone is not in use, you will receive a notification.
You can Accept or Decline the video call. Alternatively, you may reject the video call by sending a WhatsApp message: tap Message and select a quick message.
