Yesim eSIM Data Plans for South Korea

Yesim offers unlimited data eSIM plans for South Korea with validity periods ranging from 1 day to 30 days. Prices start at $8.31 USD for a 1‑day plan and go up to $65.32 USD for a 30‑day plan, all of which allow tethering and are delivered over 5G networks.

These unlimited plans are subject to Fair Usage Policy: after a period of heavy use, speeds may be throttled. Travelers who are concerned about potential speed restrictions should contact Yesim directly to confirm the specifics of the policy and the typical amount of data that can be used at normal speed.

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 a range of data options for travelers heading to South Korea. In the country‑specific offerings there are seven single‑country plans, while 21 multi‑country packages include coverage for South Korea as part of larger regional bundles. The plans vary from modest data caps such as 5 GB to unlimited options, and they run from one day up to a full year of validity. Prices span roughly $8 to $129, depending on the data amount, duration, and whether the plan is a fixed‑data package or a daily capped arrangement. Tethering is generally permitted, although performance may be throttled at higher speeds.
