eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a truly unlimited data eSIM for South Korea. The plans that carry the “Unlimited” label actually offer 1, 000 GB of high‑speed data, and the speed may be throttled once that amount has been used.

Travelers looking for unrestricted use can instead select a fixed‑data plan. A common choice is the 20 GB Travel eSIM, valid for 30 days and priced at $36.76, which offers a clear data limit without speed reduction. Other fixed‑data options are also available in the catalog, and may be more cost‑effective for most users unless a very heavy data consumer is needed.

eSIM Cards does not offer eSIM plans for South Korea that include a local phone number or SMS capability. The South Korea plans available from eSIM Cards are strictly data‑only, providing internet access for the validity period of the plan. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication.

They currently list six single‑country data plans for South Korea and two multi‑country packages that include Korea as part of the coverage. The data caps range from about 3 GB up to more than 1, 000 GB, with validity periods from 5 to 30 days and prices roughly between $8 and $69 USD. Some plans permit tethering, though the speed may be throttled; the catalog does not distinguish a separate daily‑cap category.
