Yesim eSIM Data Plans for South Korea

Yesim provides unlimited data eSIM plans for South Korea. The plans cover validity periods from 1 day to 30 days, with prices ranging from $8.21 for a single‑day plan to $64.47 for a 30‑day plan. All of these unlimited plans allow tethering and use the 5G network, but the included feature list notes that speeds may be throttled after heavy usage, indicating a Fair Usage Policy. If users want to confirm whether the throttling applies to a particular volume of traffic or to understand the typical amount of data available at normal speed, they should contact Yesim directly.

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 lists seven single‑country data plans specifically for South Korea. The available plans vary in cost from roughly $8 to $230 and in data allowance from 5 GB to unlimited, with validity periods ranging from one day up to a full year. No multi‑country plans that include South Korea are listed separately in the database.
