Roamless eSIM Data Plans for South Korea

Roamless does not provide an unlimited data eSIM for South Korea. The available options include a fixed 50GB data plan that is valid for 30 days, and several pay‑as‑you‑go data credits that start at 100GB, 150GB, or 200GB and have no expiry date.

The pay‑as‑you‑go credits are charged per megabyte used, so the listed data amount is only a reference for how much data the purchased credit buys at South Korea’s rate; unused credit remains on the account and can be topped up at any time. Choosing a fixed data plan can be more cost‑effective for most travelers, while the pay‑as‑you‑go option offers flexibility for those who may need more data or want to add credit during their trip.

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 six single‑country data plans for South Korea and thirteen multi‑country plans that include South Korea. The available plans range in price from free to about $490 and provide between roughly 500 MB and 200 GB of data at current local rates. In addition to these fixed‑data‑cap plans, Roamless sells a separate data‑credit product in 22 top‑up sizes; the credit does not expire, so unused balance can be carried over to future trips. The fixed‑data plans do not impose daily caps, and the multi‑country options allow the same data to be used in several destinations beyond South Korea.
