It seems that Koreans are very fond of apple devices, especially the tenth iPhone. This is evidenced by recent statistics of the iPhone X, which launched in the home market of its main competitor. South Korean largest operator SK Telecom launched dozens of sales on its website, and after 3 minutes there were simply no free devices left.
The public’s interest in the eighth iPhone, by the way, was only 60-70% of the seven. This is probably due to the release of the iPhone X, perhaps people simply did not want to change the well-working 7 to very similar 8. By the way, the price tag for X in South Korea is one of the highest in the world: $ 1237 for the 64-gigabyte version.
