The SIM Shop eSIM Data Plans for South Korea

The SIM Shop does not offer a genuinely unlimited data eSIM for South Korea. All of its plans for that country are defined by a specific data cap and a fixed validity period.

Instead, The SIM Shop provides fixed data plans such as a 50GB high‑speed data plan valid for 30 days or a 20GB plan also valid for 30 days. Another option is a 20GB plan that is valid for 90 days and covers South Korea together with additional Asian countries. These fixed data plans may be more cost‑effective for travelers who need a predictable amount of data, while very heavy data users might consider other carriers that offer unlimited data.

The SIM Shop does not provide any South Korean eSIM that includes a phone number or SMS capability. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that the apps they rely on are accessible in South Korea before purchasing, as some destinations may block or restrict certain services.

The SIM Shop provides a total of 6 single‑country plans for South Korea and a further 56 multi‑country plans that include South Korea in their coverage. Among its offerings, the company features both fixed data caps—48 plans that grant a predetermined amount of data for the entire validity period—and daily data cap plans—14 plans that limit the amount of data that can be used each day. Prices for these packages vary from about $4.18 up to roughly $130.67, with data caps ranging from 1 GB to 50 GB and validity periods that can be as short as one day or stretch up to a full year.
