Without WhatsApp support it will not go far.

Speaking of which, it is bizarre how the tables have turned. Whatsapp used to support everything under the sun... But now it is all Android and iPhone

To be fair there's nothing else left under this sun.

It's a chicken and egg problem tho, whatsapp doesn't support smaller platforms, and smaller platforms can't grow without app support. I remember that the uptake of Windows Phone 7 and early versions of 8 was pretty low partly because whatsapp didn't support that OS.

WhatsApp has reduced the number of platforms that they support, they had a KaiOS app but disabled it last year.

I know, but my comment was more along the lines of Windows Phone 7 coming out in 2010 and whatsapp being available a year later, and of whatsapp not having a native app for Sailfish

This one was recently up in HN: https://dumbermini.com/

They could do Telegram at least, which has a non-zero user base (not sure about India, though, which seems to be their target market), and supports third party clients. Rolling their own chat app is... well, good luck with that.
