One reason could be lack of very cheap Smartphones. I mean like good sub 1000 rupees phones.

India has a great Android phone ecosystem and the sub 10,000 rupee phones are really good. But 10,000 rupees is still quite a bit of cash for many people.

In my personal experience, poor population actually doesn't care about 'smartphone', though they care about 'Whatsapp'. Thankfully, Jio is bringing around 2000 INR (~28 USD) feature phones too, that will still run Whatsapp and Facebook etc.
