eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a plan with a truly unlimited high‑speed data allowance for South Korea. The plans that use the word “Unlimited” have a fixed 1000GB data cap; after that amount the speed may be throttled, as indicated in the features. Travelers who need a large but limited data allowance can choose from fixed‑data plans such as the 20GB package for 30 days or the 10GB package for 30 days, which are available for purchase at $32.63 USD and $24.15 USD respectively. These fixed‑data plans are often more cost‑effective for users who do not require extreme amounts of data.

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.

For the South‑Korea region, eSIM Cards lists six single‑country data plans, with no multi‑country options available. The plans cover a price range of about $7.83 to $32.63 US dollars and a data cap that varies from 3 GB to 1, 000 GB, with validity periods from 5 to 30 days. They are generally fixed data amount plans; some include daily data caps for a more flexible usage model. Tethering is permitted on these plans and speeds may be throttled in accordance with carrier policies.
