The cheapest plan that covers your trip
Each cell is the cheapest plan made for South Korea with enough data for the trip, as on the South Korea page; a cheaper regional plan, where there is one, is shown below. These are the same assumptions as the South Korea page and the trip-cost comparison. Use levels: light use about 0.3 GB a day (maps and messaging); everyday use about 1 GB a day (adds social media, music and some video); heavy use about 2.5 GB a day (a lot of video and video calls).

How we choose
We take every plan that works in South Korea, work out the data a trip of that length and use level needs (the same figures as the destination page), drop plans that are too small or expire too soon, and show the cheapest of what is left. Per-day plans are judged on the daily allowance, and an unlimited plan that slows down after a daily allowance is judged on that allowance. This is a price-and-fit comparison of the plans we sell, not a review of providers or networks, and it ignores speed, support and how long a plan has been on sale. Prices change, so the table is rebuilt from the catalogue every day.
