eSimpli eSIM Data Plans for South Korea

eSimpli does not provide a truly unlimited data eSIM for South Korea. The plans labeled “Unlimited” actually deliver 1GB per day for a set number of days, and once the 1GB/day limit is reached the speed is reduced to 1250 kbps. These plans therefore have a fixed high‑speed data allowance that is not unrestricted.

Travelers who need more data can choose one of eSimpli’s fixed data plans. For example, the eSIM South Korea 20 GB 30 days plan and the eSIM South Korea 10 GB 30 days plan offer full‑speed 5G data until the data is used, which may be more cost‑effective unless the user is an extremely heavy data consumer.

eSimpli does not provide South Korea eSIM plans that include a phone number with voice and SMS capabilities. Travelers looking for connectivity in South Korea will find that eSimpli only offers data‑only eSIMs from this provider. If a phone number or SMS service is needed, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though it is advisable to confirm that these services are accessible in South Korea before purchasing a plan.

eSimpli lists 7 single‑country and 13 multi‑country data plans that cover South Korea. The provider offers two primary plan types: daily‑data‑cap plans, where the data allowance rolls over each day, and fixed‑data‑cap plans, which give a set amount of data for the entire validity period. Across the catalog, plans range from roughly $7.95 to $108.68 and include data caps between about 1 GB and 20 GB.
