SimOptions does not provide an unlimited data eSIM for South Korea. Instead they offer fixed data plans that range from 10GB to 100GB. For example, the South Korea 100GB plan gives 100GB of high‑speed data for 180 days, while the South Korea 20GB plan supplies 20GB for 15 days.
Choosing a fixed data plan can be more cost‑effective for most travelers, particularly if they do not expect to use extremely large amounts of data. A higher‑capacity plan such as the 100GB option may be suitable for users who anticipate heavier data usage.
