Source of your information? Are you saying that over 2.32 billion people don't have access to clean drinking water? That seems way off.

Even though there may 2.32 billion people with smartphones there are large percentages of people who don't even in developed countries. For U.S.in 2015 folks who make less than $30k a year 50%. Folks older than 65 27%. Folks between 50-64 54%. Even if they own a smartphone that doesn't mean that Uber would be accessible to them.

Apologies, more people have smartphones than access to a toilet. "only" ~780 million don't have access to clean water.
