eSIM4Travel eSIM Data Plans for South Korea

eSIM4Travel does not provide a truly unlimited data eSIM for South Korea. All of its South‑Korea plans have a fixed data allowance, such as 3GB per day for the “Unlimited‑xDays‑South Korea” series or 20GB, 30GB, or 50GB for the other fixed‑data plans.

Travelers who need a large amount of data can choose a fixed‑data plan that offers a high allowance, for example the 50GB/30‑day plan or the 20GB/30‑day plan. These plans give a set amount of high‑speed data that must be used within the validity period, and they can be more cost‑effective than a plan that throttles after a smaller limit.

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.
