Yesim eSIM Data Plans for South Korea

Yesim provides eSIM options for South Korea that offer unlimited data. These plans have validity periods ranging from 1 day up to 30 days, with prices varying accordingly.
Because the plans are listed with a data cap of “Unlimited, ” they allow continuous data usage, but Speeds may be throttled after a Fair Usage Policy threshold is reached. If travelers are concerned about potential speed restrictions, they should contact Yesim directly to confirm whether the FUP applies and the typical data amount that can be accessed at normal speed.

Yesim does not provide South Korea eSIM plans with a phone number or SMS capability. Only data‑only eSIMs are offered for this destination. Travelers can use internet‑enabled messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection for communication. Because some destinations may block or restrict access to specific apps or VoIP services, users should confirm that the apps they rely on are available in South Korea before purchasing an eSIM.

Yesim offers twelve single‑country data plans and twenty‑five multi‑country plans that cover South Korea. The available plans span a price range from about $2.88 to $228.99 and data caps from 1 GB up to unlimited. Some packages provide a fixed amount of data for the entire validity period, while others use a daily data cap that resets each day. Tethering is generally permitted but speeds may be throttled on certain plans.
