Here's where I think is the difference between the western world and NBU - The Next Billion Users.

Skype and Whatsapp video are the only two ones that work reasonably well in India with shaky mobile bandwidth. I mentioned Zoom as well.

But here's the thing - have you used Skype Web ? There's no installation needed.

Interesting point. I wouldn't have assumed that, because I've never had a good experience with Skype's handling of unstable connections here in Canada. That said, no I haven't tried Skype for web.

Regarding the rest of the world, WhatsApp definitely comes to mind. For chat, video, and audio.
