eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not offer a genuinely unlimited data eSIM for South Korea. The plans that carry the “Unlimited” label—such as the South Korea Unlimited eSIM for 5 days and 10 days—include a large 1 000GB data allowance but the service specifies that speed may be throttled once the cap is reached. If a traveler needs truly unrestricted high‑speed data, a fixed data plan would be more appropriate. Examples of fixed‑data options that are available in the South Korea market include a 20GB plan valid for 30 days and a 100GB plan that is valid for either 5 or 10 days. These plans provide high‑volume data without advertising a true unlimited allowance.

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 provides six single‑country data plans that cover South Korea and two multi‑country plans that include South Korea coverage. The plans vary in price from about $8.02 to $66.86 and in data allocation from 3 GB up to 1, 000 GB for the validity period, which ranges between 5 and 30 days. Some plans offer a fixed data amount for the entire duration while others provide a daily data cap that restores each day, and a few include tethering permission though speed may be throttled.
