Roamless eSIM Data Plans for South Korea

Roamless does not provide a truly unlimited data eSIM for South Korea. The available plans are fixed‑data options with caps of 200GB, 150GB, and 100GB, all of which are offered with no expiration period.

If you need a large amount of data without the need for an unlimited allowance, these fixed plans can be a more cost‑effective choice, especially for moderate to heavy data usage. For example, the 200GB plan costs $490.00 USD and includes tethering, while the 100GB plan costs $245.00 USD. Choosing a fixed‑data plan may be preferable unless you are an exceptionally high‑volume user who would benefit from a truly unlimited data cap.

Roamless does not offer South Korean eSIM plans with a phone number or SMS capability. The provider only sells data‑only eSIMs for South Korea. Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are available in South Korea before purchasing, as some destinations may block or restrict access to certain apps.

Roamless offers 28 single‑country data plans as well as 13 multi‑country plans that include South Korea. The plans vary widely in cost, ranging from free to about $490, and in data capacity from 525 MB up to 200 GB. Some plans provide a fixed amount of data that drains over the validity period, while others offer a daily data cap that replenishes each day during the plan’s lifetime.
