CloudOn eSIM eSIM Data Plans for South Korea

CloudOn eSIM does not provide a truly unlimited high‑speed data plan for South Korea. The plans that carry the “unlimited” label actually offer 2GB of data per day; after that threshold is reached the speed is reduced to 1000 kbps. For travelers who need more data without daily limits, CloudOn sells fixed‑data options. For example, a 50GB plan for 30 days costs $37.99 USD and a 20GB plan for 30 days costs $23.99 USD. Choosing a fixed data plan can be more cost‑effective unless a user requires very high data consumption.

CloudOn eSIM does not offer a South Korea eSIM plan that includes a phone number or SMS capability. Only data‑only eSIM packages are available through CloudOn for South Korea.

Travelers who need voice or text communication can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, which provide calls and messages without requiring a traditional phone number.

CloudOn eSIM offers 11 single‑country plans that cover South Korea and an additional 15 multi‑country plans that include South Korea among other destinations. The plans span a price range of roughly $3.99 to $177.49 and provide data allocations from 500 MB up to 100 GB for validity periods between 3 and 180 days. Some plans are daily‑cap plans—allowing a set amount of data each day—while others are fixed‑data plans that provide a total data packet that does not reset each day.
