The closest Appstore to me is ~2500km and over the border. Dozens of Millions of people here don't matter, apparently.
Of course, there are also important factors like the average worker being dirt poor. Who is buying an iphone on a 300-400USD/mo equivalent salary? It would take years and years of saving to afford one, or a choice to put yourself into hard to repay debt for a status symbol? I would imagine the average person there buys the cheapest phones possible and not the highest end name brand phones every few years like working and middle class westerners do.
