Facebook-owned WhatsApp on Tuesday rolled out its group calling feature – for both voice and video options – on iOS and Android devices for its 1.5 billion users.

The group calling feature supports up to four people simultaneously. You can make a group call with up to four people total — anytime and anywhere. Just start a one-on-one voice or video call and tap the new “add participant” button in the top right corner to add more contacts to the call,” WhatsApp said in a statement.

The company says it engineered the feature to work under less-than-stellar network conditions, so you can video chat a friend or family member from a far-flung locale so long as you can get yourself online.

Calls are also end-to-end encrypted, like all chats on the platform. On the encryption side, WhatsApp has long worked with WhisperSystems to cover all messages and calls on its platform from prying eyes and ears. That said, the relationship between the two become a little more complicated this year when WhatsApp co-founder Brian Acton donated $50 million of his wealth — accumulated from Facebook’s acquisition of his company in 2014 — to the Signal Foundation, which is associated with WhisperSystems.
