eSimfly eSIM Data Plans for South Korea

eSimfly does not provide a truly unlimited data eSIM for South Korea. All of the plans that carry “Unlimited” in their name actually offer a fixed daily data allowance – for example, the South Korea Unlimited 3‑day plan supplies 1GB per day and, once the limit is reached, the speed drops to 5000kbps. The same pattern applies to the South Korea Unlimited 30‑day and other daily‑limit plans, which each provide 1GB per day with a reduced speed of 5000kbps after the data cap is used.

For travelers who need more data, eSimfly offers fixed‑data options. One such example is the South Korea 50GB 30‑day plan, which gives a total of 50GB of high‑speed data for a month. These larger data packages can be more economical for heavy data usage compared to the daily‑limit “Unlimited” plans.

eSimfly does not offer South Korea eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available from this provider for travelers in South Korea.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage, which work over the data connection provided by the eSIM.

eSimfly offers a total of 54 data plans for South Korea, split between single‑country and multi‑country options. There are 17 single‑country plans that cover South Korea only, and 37 multi‑country plans that include South Korea among other destinations. The plans range in price from about $1.90 to $100.19 and provide data caps from 1 GB up to 100 GB, with validity periods between 3 and 365 days. Some plans use a fixed data amount, while others cap a certain amount of data each day, allowing travelers to choose the structure that best fits their usage pattern.
