but also people with smartphones, that do not have Internet.

Really?
In my country is a country that is on the list of the poorest countries in the world and everyone who has smartphone has internet, in my house for example we all have computers, smartphones and we all can not live without internet... I'm trying to see which country is that there are people with smartphone without access to the internet, because the mobile phone operators offer internet access and the price is very low
It is doubtful that even in the long-term future everyone is going to have internet on their smartphone.
as I said before, mobile phone operators offer internet access at very low prices, all people (at least in my country) that has smartphone has internet at very low prices.
Imagine a store without public wifi. ?
Eh? in my country only in the university they offer access to free Wi-Fi
