But your comment conflates "one of the most expensive smartphones" with "having any connection to the digital world". No disagreement that connectivity is critical and that mobile devices are an efficient way to get there on a low income, but iPhones are definitely not. My mom doesn't have a working computer in her house atm, and her phone cost 200 dollars (or free with carrier subsidy). There's pretty much no reason to get an iPhone on purely functional grounds, just as there would be no reason to get a $700 Galaxy S7.
Though I should note that ios has moved downmarket when they started selling older models, which filled some of this gap.
