eSIM Cards eSIM Data Plans for South Korea

eSIM Cards does not provide a truly unlimited data plan for South Korea. All of its current South‑Korea offerings give a fixed data allowance – the largest available plan supplies 1, 000 GB for 5 or 10 days, after which the speed may be throttled. The fixed‑data plans are also available, such as 20 GB, 10 GB and 5 GB for 30 days, which can be more cost‑effective for most travelers.

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 offers six single‑country data plans for South Korea. All of these plans are priced between $.88 and $32.82 and provide data caps ranging from 3 GB up to 1, 000 GB, with validity periods from 5 to 30 days. The plans allow tethering and may be subject to speed throttling during peak times. No multi‑country plans are currently available for this country.
