eSIMCard eSIM Data Plans for South Korea

eSIMCard does not provide a truly unlimited data eSIM for South Korea. The plans that carry the word “Unlimited” all have a fixed high‑speed data allowance, typically 1 GB per day, after which the connection speed is throttled to a reduced level such as 512 kbps or 2000 kbps. For travelers who expect to use more data, a fixed‑data plan can be more economical; for example, eSIMCard offers a 100GB plan valid for 30 days at $97.83 USD, and a 100GB plan for 31 days at $56.47 USD. These larger data bundles do not throttle after the cap is reached, providing higher‑speed usage throughout the validity period.

eSIMCard does not provide a South Korea eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIM plans for South Korea, so travelers will not receive a number for inbound or outbound voice or text messages. Call and messaging can still be handled via popular VoIP apps such as WhatsApp, Telegram, or iMessage that work over the data connection.

eSIMCard offers 31 single‑country data plans and 100 multi‑country data plans for South Korea. These plans come in two main types: daily data‑cap options, which give a set amount of data each day, and fixed data‑cap options, which provide a total data allowance for the entire validity period. Prices range from roughly $2.10 to $395.07, while data caps span from 1 GB up to 100 GB.
