CloudOn eSIM eSIM Data Plans for South Korea

CloudOn eSIM provides several fixed data plans that are marketed with “Unlimited” in the name for South Korea. These plans give a daily high‑speed allocation (either 2GB/day or 3GB/day) for a set validity period (for example 5 days, 7 days, or 10 days). Once the daily allowance is exhausted the speed drops to 1Mbps, so the data is not truly unlimited at full speed.

If unlimited high‑speed data is not required, CloudOn eSIM also offers fixed data plans with larger hard limits, such as the 20GB plan for 30 days or the 50GB plan for 30 days. These plans keep the full speed for the entire validity period until the data cap is reached.

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 provides 15 single‑country plans and 24 multi‑country plans that include coverage in South Korea. The available offerings range in price from about $3.99 to $99.99 and feature data caps between 500 MB and 100 GB. Of the plans, 23 are based on fixed data amounts while 16 use a daily data cap, giving travelers options for short‑term or longer‑term usage.
