Apparently one of the most interesting things about this is that the phone is free for students who are writing this Korean version of the SAT/Leaving cert exam. I like the idea, however I think that person constraint should be enough to keep students away from their phones. At the end of the day, we live in a wifi omnipresent environment, especially in South Korea, the market at which this is aimed at.

Overall, I think that they should just make the plane/flight option easily accessible without going into the settings. Also, you could argue that this is a great way to keep the easily distracted people out of University. [Korean highschool/ college entry exams are a lot more important than they are for Europeans and Americans]
