eSIMCard does not provide truly unlimited high‑speed data plans for South Korea. All of the products that have “Unlimited” in their name only contain a small, fixed amount of high‑speed data—typically 1GB or 2GB—after which the speed is throttled to 512kbps or 2000kbps. For example, the “eSIM Data For Unlimited in 1Day, South Korea” is 1GB per day, and the “eSIM Data For Unlimited Plus in 1Day, South Korea” is 2GB per day with a reduced speed of 2000kbps once the allowance is reached.
Travelers who need a larger daily data allowance can choose from eSIMCard’s fixed‑data plans that offer 100GB for 30 days or similar high‑volume options. These plans provide unlimited high‑speed usage without throttling, but they come at a higher price. Because the “Unlimited” plans are not truly unlimited, selecting a fixed high‑data plan may be more cost‑effective unless a user consumes data beyond the capped amount each day.
eSIMCard does not provide a South Korea eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIM plans for South Korea, so travelers will not receive a number for inbound or outbound voice or text messages. Call and messaging can still be handled via popular VoIP apps such as WhatsApp, Telegram, or iMessage that work over the data connection.
eSIMCard provides 31 single‑country plans and 97 multi‑country plans for South Korea.
These plans cover a price range of roughly $2.10 to $395.07 USD and a data cap range from 1 GB up to 100 GB.
The catalog includes both fixed‑data‑cap options and daily‑data‑cap selections.
