CloudOn eSIM eSIM Data Plans for South Korea

No, CloudOn eSIM does not provide a truly unlimited data plan for South Korea. The plans that list “Unlimited” in their names still have a fixed daily data allowance, such as 3 GB/day or 2 GB/day, and once that quota is reached the speed is throttled to 1000 kbps.

If a traveler needs more high‑speed data, CloudOn eSIM offers fixed data plans that provide large amounts of data for a set period. For example, the South Korea_50GB_30DAYs plan gives 50 GB for 30 days at $37.99 USD, and the Asia 100 GB‑180days plan offers 100 GB for 180 days at $86.99 USD. These plans grant unrestricted high‑speed data for the specified amount, which can be more cost‑effective for heavy‑data users.

CloudOn eSIM only offers data‑only eSIM plans for South Korea, and no plan includes a local phone number or SMS capability. Travelers who need voice or text services will need to rely on internet‑based solutions. VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection, but some destinations may block or restrict specific apps or services, so it is advisable to verify that the chosen apps are accessible in South Korea before purchasing a plan.

CloudOn eSIM lists 11 single‑country plans and 21 multi‑country plans that cover South Korea. The overall price range for these plans is approximately $3.99 to $126.99, and data caps span from 500 MB up to 100 GB. Some options provide a fixed amount of data for the entire validity period, while others impose a daily data cap, giving travelers flexibility depending on their usage patterns.
