Voyasim eSIM Data Plans for South Korea

Voyasim does not provide an unlimited data eSIM plan for South Korea. All of its South‑Korea offerings have a fixed data cap, such as the 50GB 30‑day plan or the 20GB 30‑day plan, each with a 5G network and a validity of 30 days.

If you need a large data allowance, you could choose one of these fixed data plans. For example, the South Korea 50GB 30Days plan gives 50GB of high‑speed data for 30 days and may be more cost‑effective for most travelers unless you are an extremely heavy data user.

Voyasim does not offer an eSIM for South Korea that includes a phone number or SMS capability. Only data‑only plans are available. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may restrict access to specific apps, so it is advisable to verify that the apps you rely on are accessible in South Korea before purchasing.

Voyasim offers a broad selection of data plans that can be used in South Korea. In its catalogue there are 33 single‑country plans that cover South Korea alone, and 58 multi‑country plans that include South Korea as part of a larger regional itinerary. Prices start around $0.50 and can reach $134.50, while data caps range from 100 MB to 50 GB, and validity periods vary from one day up to 365 days. The single‑country options typically provide a fixed data amount for a set period, whereas the multi‑country plans bundle data across several regions, often with a daily or total cap that stretches across the covered countries.
