A touch over 70,000 a month for unlimited data and a bunch of minutes/text on KT. I didn't pay anything upfront for the phone and I have insurance on it. The phone is a galaxy nexus. Korea sells their phones unlocked which is a thing of beauty, so far I've used it in Philippines, Thailand, China, US and South Africa. Thing of beauty. I could see needing the GPS in a big city, I haven't lived anywhere big enough yet to warrant that and the countryside is reasonable to navigate sans GPS. But as you say, each to his own.
