YonoSIM eSIM Data Plans for South Korea

YonoSIM does not provide an unlimited data eSIM plan for South Korea. Instead, the provider offers fixed data plans that must be used within a set validity period. Two examples of readily available options are the South Korea 50GB 30Days plan priced at $32.99 USD and the South Korea 20GB 30Days plan priced at $15.99 USD. These plans supply high‑speed 5G data for 30 days, and selecting a larger fixed plan can be more cost‑effective for travelers who need substantial data usage, though they are not unlimited.

YonoSIM does not provide a South Korea eSIM that includes a phone number, inbound or outbound voice calls, or SMS capability. The only plans available for South Korea are data‑only eSIMs. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these services are accessible in South Korea before purchasing.

YonoSIM provides a broad selection of plans that cover South Korea. The operator offers 132 single‑country data plans that are specifically tailored for use within South Korea, and an additional 210 multi‑country plans that include South Korea among other destinations. Plans come in both fixed‑data and daily‑cap styles; 61 options have a fixed data amount, while 281 are daily‑cap plans that reset each day. Prices for South Korean coverage range from about $1.99 to $489.99, and data caps vary from 500 MB up to 50 GB, giving travelers a wide spectrum of choices.
