Rare, custom made, top of the line I’m guessing. They can be sold on eBay - probably be most or all of NK’s GDP for the year.
Yes, you are probably right. And let Kim "what's his face" make money to feed his people (as if he would do that!)
But these people need to get out. When they do, they can buy whatever smartphones they want. Not that that would be their first priority.
I'm sorry, I grew up in the Cold War and these imprisoned people have such a brief window of freedom. I hope and pray that some ... or maybe even all? (one can dream, right?) ... are protected and make their way to freedom.
