Yesim eSIM Data Plans for South Korea

Yesim does offer unlimited data eSIM plans that work throughout South Korea. The unlimited options range from a 1‑day plan priced at $8.22 USD to a 30‑day plan costing $64.58 USD. All of these plans allow tethering and are provided on 3G, 5G, and LTE networks. The plans note that while data is unlimited, speeds may be throttled after heavy usage, which is a common fair‑usage policy. If you need confirmation about speed restrictions or typical data limits at full speed, it is best to contact Yesim directly for the most up‑to‑date information.

Yesim does not provide eSIM plans for South Korea that include a phone number or SMS capability. The provider only offers data‑only eSIMs for this destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging without needing a local phone number.

Yesim offers 8 single‑country data plans specifically for South Korea and 20 multi‑country plans that include South Korea. Across all plans the price ranges from roughly $0.53 to $128, while the data cap ranges from 100 MB up to unlimited. The single‑country options provide fixed data amounts that are valid for 1 to 365 days, and the multi‑country plans bundle coverage across several destinations.
