Yesim eSIM Data Plans for South Korea

Yesim sells unlimited data eSIM plans for South Korea, with validity options ranging from 1 day to 30 days. Prices start at $8.05 USD for a 1‑day plan and go up to $63.24 USD for a 30‑day plan, all of which use 5G connectivity.

All of these plans are marked as unlimited and permit tethering. The speed may be throttled after heavy use under the Fair Usage Policy. If you are concerned about possible speed restrictions, contact Yesim directly to confirm 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.

The directory lists 7 single‑country eSIM options that apply to South Korea and 21 multi‑country bundles that also cover the country. The single‑country plans range in price from about $8.05 to $125.34 and carry data allowances from 5 GB up to unlimited, while multi‑country packages follow the same overall price and data ranges. Plan types differ only in the length of validity (1–365 days) and the fact that some are flat‑rate data packages rather than daily caps. Tethering is permitted on most plans, and speed may be throttled after a threshold.
