Bordersim does not provide an unlimited data eSIM for South Korea. All of its South‑Korea plans have a fixed data cap, with the largest offering 50 GB for 30 days or 50 GB for 180 days.
Travelers who need a large amount of data can choose one of Bordersim’s fixed data plans, such as the South Korea 50 GB 30Days plan or the Asia‑20 50 GB 180Days plan. These plans are generally more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a truly unlimited option.
