eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a truly unlimited data eSIM for South Korea. The plans labeled “Unlimited” in the name actually grant a fixed high‑speed allowance of 1,000 GB; after that limit the speed is throttled.
Instead, eSIM Cards offers fixed data plans that may be a more cost‑effective choice for most travelers. Examples include the 20 GB plan for 30 days at $24.80 USD, the 10 GB plan for 30 days at $24.80 USD, and the 5 GB plan for 30 days at $13.40 USD. These plans provide a set amount of high‑speed data, after which the connection speed is reduced. Choosing a fixed data plan is typically best unless a user requires a very high total data allowance.

eSIM Cards does not offer a South Korea eSIM that includes a local phone number or SMS capability. The provider only sells data‑only plans for the country. Travelers who need voice or text communication can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, which work without a phone number or SMS support.

eSIM Cards offers six single‑country data plans for South Korea, covering a price range of $8.04 to $26.14 USD and data caps from 3 GB to 1,000 GB. All six plans are fixed‑data‑amount offerings, valid for 5 to 30 days, and they allow tethering but speeds may be throttled. No multi‑country plans are available from this provider for South Korea.
