South Korea eSIMs
Korea has some of the fastest mobile data anywhere and one of the more confusing visitor markets, because the three national operators sell tourist products directly alongside dozens of resellers. SK Telecom has the broadest rural coverage, KT and LG U+ compete hard on price in Seoul and Busan. The choice that matters most is data-only versus data plus a Korean number: several services and delivery apps expect a local number, and a data-only eSIM will not get you one. Listings here say which network carries the plan, whether calls and texts are included, and how activation works if you land late at Incheon.
