eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide any unlimited‑data eSIM plan for South Korea. All of the plans listed for that destination have a hard data cap, ranging from 10 GB to 100 GB, and a fixed validity period.

Travelers who need a large amount of data can choose from the fixed data plans that eSIM Cards offers. For example, the South Korea 20 GB Travel eSIM for 30 days gives 20 GB of high‑speed data, while the Global 100 GB plans for 5 days or 10 days provide 100 GB of data for a short period. These fixed‑data options are generally more cost‑effective for most users unless a traveler expects to consume data well beyond the plan’s allowance.

eSIM Cards does not provide a South Korea eSIM plan that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for South Korea. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in South Korea before purchasing, as some destinations may block or restrict certain apps.

eSIM Cards offers four single‑country plans for South Korea and an additional two multi‑country plans that also include South Korea in their coverage. The plans vary mainly in data allocation, which is either a fixed data amount (e.g., 3 GB‑100 GB) or a daily data cap that rolls over within the validity period. Prices for these plans range from roughly $8.12 up to $69.05, and the data caps cover 3 GB through 100 GB, with validity periods between 5 and 30 days. Tethering is permitted on some of the plans.
