Yesim eSIM Data Plans for South Korea

Yesim offers unlimited data eSIM plans for South Korea. The provider supplies a range of options, from a 1‑day plan priced at $6.38 USD to an 80‑day plan costing $126.36 USD, with validity periods spanning 1 day to 80 days. All unlimited plans cover South Korea on a 5G network and allow tethering, but speeds may be throttled after heavy usage, consistent with a common Fair Usage Policy. If you need specific details about the FUP threshold or typical data that remains at normal speed, contact Yesim directly for confirmation.

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.
