Yesim eSIM Data Plans for South Korea

Yesim sells several unlimited data eSIM plans for South Korea. The plans range from 1 day to 30 days of validity and cost between $6.38 and $91.71 USD, depending on the chosen duration. All plans are marked “isUnlimited = true” and support 5G connectivity with tethering enabled.

Speeds may be throttled after heavy use under a Fair Usage Policy; normal 5G speed may be capped after a certain threshold. Travelers who wish to confirm the exact limits of the FUP or the maximum data available before throttling should contact Yesim directly for clarification.

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 eight single‑country data plans for South Korea and 25 multi‑country plans that include South Korea. The plans span a price range from roughly $3.13 to $231.01 and feature data caps between 1 GB and unlimited. Some plans provide a fixed data amount, while others allow data that is allocated daily or resets during the validity period. Tethering is permitted on most plans, though speeds may be throttled after certain thresholds.
