eSIM4Travel eSIM Data Plans for South Korea

eSIM4Travel does not offer a truly unlimited high‑speed eSIM for South Korea. The plans that carry the “Unlimited” label provide 3GB of high‑speed data each day; once that limit is reached, speed is throttled to 1000kbps. For travelers who need more uninterrupted data, eSIM4Travel offers several fixed‑data options, such as a 50GB plan valid for 30 days, a 30GB plan also valid for 30 days, and a 20GB plan within the same period. Choosing one of these fixed data plans can be more cost‑effective for those who use a lot of data while traveling.

eSIM4Travel does not currently offer a South Korea eSIM plan that includes a phone number or SMS capability. The only available South Korea plans from eSIM4Travel are data‑only options.

Travelers who need voice or text calls can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific VoIP apps, so it is advisable to verify that the apps relied upon are accessible in South Korea before purchasing a plan.

eSIM4Travel lists 21 single‑country data plans covering South Korea and 12 multi‑country plans that include South Korea. Prices span from $0.69 to $77.36 USD, with data caps ranging from 1 GB to 50 GB. Plans are offered in two main styles: fixed‑data‑cap packages, where the total amount of data remains the same for the entire validity period, and daily‑data‑cap packages, which grant a set amount of data each day.
