eSIMPhoney does not currently provide an unlimited data eSIM for South Korea. Their South Korean offerings are all fixed‑data plans with caps of 10GB, 20GB, or 50GB. For travelers who need large data allowances, eSIMPhoney lists options such as the Asia 50GB plan valid for 180 days at $106.35 USD and the Asia Plus 50GB plan for the same duration at $118.16 USD. Smaller plans are also available, such as the Asia 20GB for 90 days at $47.26 USD and the Asia 10GB for 30 days at $27.17 USD. Choosing a fixed data plan may be more cost‑effective for most users, unless a traveler requires very high data usage that would exceed the available caps.
