eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans that carry “Unlimited” in their name actually offer 1 000GB of high‑speed data; after that amount the speed may be throttled.

For travelers needing a fixed data allowance, eSIM Cards offers alternatives such as a 20GB eSIM valid for 30 days, which costs $36.31 USD, and a 100GB eSIM that is valid for 5 or 10 days and covers South Korea as well as 98 other countries. These examples illustrate the type of high‑data plans available, though a broader range can be found on the eSIM Cards catalog.

eSIM Cards does not offer eSIM plans for South Korea that include a local phone number or SMS capability. The South Korea plans available from eSIM Cards are strictly data‑only, providing internet access for the validity period of the plan. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication.

eSIM Cards offer six single‑country data plans and two multi‑country plans for South Korea. The options span a price range of roughly $8 to $67 and data caps from 3 GB up to 1 TB. Some single‑country plans provide a fixed data amount for the entire validity period, while other plans apply a daily data cap to manage usage. Many plans also permit tethering, though speeds may be throttled at higher usage levels.
