Yesim eSIM Data Plans for South Korea

Yesim provides unlimited data eSIM plans for South Korea. The available packages range from $8.17 USD for a 1‑day validity up to $64.22 USD for a 30‑day validity, with intermediate 7‑day and 15‑day options. All of these packages allow tethering and state that speed may be throttled under a Fair Usage Policy, meaning that after heavy use the data may be slowed. If a traveler wants details on how much data remains at full speed before throttling, the best option is to contact Yesim directly to confirm the policy specifics.

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 lists 27 data plans for South Korea, with 7 single‑country plans and 20 multi‑country plans. The price range spans from $8.17 to $127.27 and the data caps vary between 5 GB and unlimited. Some plans include the option for tethering and may have speed throttling applied.
