The worst thing about your favorite chat app is trying to get your friends and family to use it. WhatsApp may be the most popular messaging platform in the world, but in the United States, it is hardly universally adopted. On the contrary, you'll find plenty of people who don't use it at all. In short, it's difficult to get a whole group to commit to any one platform, which can make casual video calls frustrating: If you don't use WhatsApp, and your friends are hosting a call, what are you supposed to do? You can't join a WhatsApp call without a WhatsApp account.
That's now changing. Meta, WhatsApp's parent company, announced "guest calling" on Wednesday. Now, any WhatsApp user can invite any non-WhatsApp user to a call, even if the recipient doesn't have an account. These calls still get the same core perks as traditional WhatsApp calls, Meta says: They're free and end-to-end encrypted, so you won't be compromising on your privacy by calling a non-WhatsApp user this way.
Non-WhatsApp users are still limited. Meta says these users always need a call host's approval to join. If you're a non-WhatsApp user, you'll find yourself in a waiting room until the call host lets you in. Meta also says that you can be kicked off the call at any time, and you won't be able to see other callers' phone numbers. You won't be able to send messages or add other users to the call. You are purely a participant.
How to invite someone without a WhatsApp account to a WhatsApp call
If you're trying to add a non-WhatsApp user to a call, first head to the Calls tab in the app. Here, hit (+), create a call link, then send it to the recipient. Meta says the user can open the link in their computer browser, enter their name, and join. This applies to one-on-one calls as well as calls with up to 32 people. While guests will have the aforementioned limits, they do have some features available to them. They can share their screen, react with emojis, or raise their hand.
WhatsApp isn't the first chat app to offer such a feature. Apple's FaceTime platform, for example, lets you create call links that anyone can join, whether they're calling in on an Apple device or a device running Android or Windows (or Linux, for that matter).
