Yesim eSIM Data Plans for South Korea

Yesim provides several eSIM plans for South Korea that offer unlimited data. These plans vary in validity from 1 day to 30 days and have prices ranging from $4.03 USD to $65.59 USD. All unlimited plans use the 5G network and include tethering; the provider notes that speeds may be throttled after heavy usage, which is a Fair Usage Policy (FUP) applied to maintain network quality.

If you are concerned about potential speed restrictions or want to confirm the typical amount of data you can use at normal speed, it is recommended to contact Yesim directly to verify the FUP details for the South Korea unlimited plans.

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.
