Saily’s South Korea eSIM starts at $3.99 for 1 GB. For about a week, the 5 GB plan ($10.99) covers maps, rides and messaging.
The catch: plans are data only, so you get no local phone number for calls or texts.
South Korea trips usually mix Seoul with Busan or Jeju, by KTX train or short flights. Korea runs on its own map and taxi apps, which need data, and a South Korea eSIM is ready at Incheon.
