While WhatsApp and most other messengers support end-to-end encryption, Signal is probably still your best choice (of the popularly used options) when you want your conversations and calls to stay private. Given that all communication on Signal is encrypted, including group video calls, the company is running into some unique challenges that need to be addressed when scaling its service. As such, Signal has only supported group calls with up to five participants until now, but it has finally managed to significantly up the limit to 40 people at a time.
