eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a truly unlimited data plan for South Korea. Its plans labeled “Unlimited” actually give 1 000GB of high‑speed data for 5 or 10 days, after which the connection speed may be reduced, yet the data allowance remains capped. The plan allows tethering.

For travelers who want straightforward data limits, eSIM Cards offers fixed‑data options such as 20GB for 30 days (US $25.02), 10GB for 30 days (US $25.02), and 5GB for 30 days (US $13.52). These plans can be more cost‑effective for most users, especially if a heavy‑data user is not needed.

eSIM Cards does not offer a South Korea eSIM that includes a local phone number or SMS capability. The provider only sells data‑only plans for the country. Travelers who need voice or text communication can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, which work without a phone number or SMS support.

eSIM Cards provides six single‑country data plans for South Korea, with prices ranging from about $8.11 to $26.37 and data allowances between 3 GB and a full 1,000 GB, all valid for 5 to 30 days. No multi‑country plans are currently available for this country. Some plans allow tethering, although speeds may be throttled after the data cap is reached.
