YonoSIM eSIM Data Plans for South Korea

YonoSIM does not offer an unlimited data eSIM for South Korea. Travelers who need a stable data allowance can choose from fixed‑data plans, such as a 50GB 30‑day plan priced at $32.99 USD or a 20GB 30‑day plan priced at $15.99 USD. These options provide clear pricing and data limits, which can be more cost‑effective unless a traveler requires an extremely high data volume.

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 offers 24 single‑country data plans for South Korea, in addition to 55 multi‑country plans that include South Korea as part of a broader coverage package. The plans range from daily or short‑term offerings to a 365‑day option, with data caps between 500 MB and 50 GB and prices from about $1.80 up to $94.99. Some packages apply a reduced speed of 384, 512, 1 000 or 128 Kbps once the data limit is reached, providing a clear distinction between standard and capped usage.
