eSimfly eSIM Data Plans for South Korea

eSimfly does not provide a truly unlimited data eSIM for South Korea. Their plans that carry the label “Unlimited” actually allot a fixed amount of high‑speed data—1GB per day for plans covering South Korea only, and 3GB per day for the Asia‑wide variant—before any additional throttling would apply. For travelers who need large data allowances without daily caps, eSimfly offers fixed‑data plans such as the South Korea 30 GB plan for 30 days at $11.63 USD or the South Korea 50 GB plan for 30 days at $18.69 USD. These options can be more cost effective unless very heavy usage is required.

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 offers 19 single‑country and 21 multi‑country data plans for South Korea. Prices range from about $1.56 to $77.47 and data caps vary from roughly 1 GB to 100 GB, with validity periods spanning 1 to 365 days. Some plans use a daily data cap structure, giving a fixed amount of data each day, while others provide a fixed total data amount for the entire validity period.
