Real-world experience

Speed tests in metro areas such as Seoul／Busan commonly reach tens to hundreds of Mbps (depending on signal and load). All-day navigation + social + video is usually not deliberately capped. With a Korea local IP, local apps／ticket snatching usually feel smoother. For reference only; results are not guaranteed for every traveler.
