Yesim eSIM Data Plans for South Korea

Yesim offers unlimited data eSIM plans designed for South Korea. Validity ranges from 1 day to 30 days, with prices between $8.12 USD for a one‑day plan and $63.81 USD for a 30‑day plan. Each unlimited option permits tethering and states that speeds may be throttled after heavy usage.

Because Yesim applies a Fair Usage Policy, data speeds can be reduced if a user exceeds typical usage thresholds. Travelers who need confirmation on the amount of data that remains at normal speed should contact Yesim directly before purchasing.

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 provides seven single‑country data plans and twenty multi‑country plans that cover South Korea. The single‑country options generally come with a fixed data allowance ranging from 5 GB to unlimited, while the multi‑country plans offer a daily data cap that can also vary, allowing users to choose between a larger, capped data pool or a more flexible unlimited option depending on the chosen package. Prices for both types vary widely—from about $8 USD for the lowest‑tier plans up to roughly $126 USD for the most comprehensive packages. Some plans allow tethering, and speeds on very high‑usage plans may be throttled.
