eSimfly eSIM Data Plans for South Korea

eSimfly does not provide a truly unlimited data eSIM for South Korea. All of the plans labeled “Unlimited” give 1GB of high‑speed data per day and, once that limit is reached, the connection speed is reduced, which means the plans are not unlimited in the usual sense.

Travelers who need larger data allowances can choose from eSimfly’s fixed‑data plans, such as the 50GB for 30 days plan that costs $18.69 USD. Other example plans include a 60‑GB package for 365 days priced at $125.62 USD and a 100‑GB plan for 180 days that costs $257.40 USD. These larger packages provide a fixed amount of data without the daily cap that applies to the “Unlimited” named plans.

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 23 single‑country data plans that cover only South Korea and 87 multi‑country plans that include South Korea in a broader itinerary. The plans’ prices range from about $1.48 up to $257.40, and their data caps span from 1 GB to 100 GB, with validity periods between one day and a full year. Besides fixed‑data‑cap offerings, eSimfly also delivers daily‑data‑cap plans that limit how much data can be used each day; many of the plans allow tethering.
