eSimfly eSIM Data Plans for South Korea

eSimfly does not have a truly unlimited high‑speed data plan for South Korea. All plans labeled “Unlimited” in the name actually provide 1 GB of high‑speed data per day; after the daily cap is reached, the connection is either throttled or data stops, so the speed is not maintained. If a traveler prefers a larger, fixed data allowance, eSimfly offers plans such as South Korea 50 GB 30 days for $18.69 USD or Asia 100 GB 180 days for $224.40 USD, which can be more cost‑effective for heavy data use.

eSimfly does not provide eSIM plans that include a phone number or SMS capability for South Korea. All available South Korea eSIMs from this provider are data‑only, with no inbound or outbound voice or text services included.

Travelers who need messaging or calling can rely on internet‑based VoIP apps such as WhatsApp, Telegram, or iMessage, which work over the data connection offered by the eSIM.

eSimfly provides 26 single‑country data plans for South Korea and 76 multi‑country plans that include South Korea as part of a larger regional package. The single‑country plans range from roughly $1.08 to $224.40 and offer data caps between 1 GB and 100 GB, with validity periods ranging from 1 to 365 days. The multi‑country plans follow a similar pricing spectrum and data range, allowing travelers to use the same data allowance across several destinations. Plans are divided into fixed data‑cap options—which give a set amount of data for the entire validity period—and daily data‑cap options, which limit usage on a per‑day basis; there are 85 fixed‑cap and 17 daily‑cap plans available.
