WiiLink eSIM Data Plans for South Korea

WiiLink currently offers 89 single‑country data plans for South Korea, with no multi‑country options available. The plans cover a price range from about $1.88 to $61.90 and provide data caps between 1 GB and 50 GB, valid for 1 to 30 days. Among these, 47 are daily‑data‑cap plans—where the allowance resets each day—and 42 are fixed‑data‑cap plans that deliver a set amount of data for the entire validity period.

WiiLink’s South‑Korea offerings do not include a true unlimited data eSIM; all plans list a fixed data cap, with the highest available high‑speed allocation being 5 GB per day on several short‑term “Unlimited” labeled plans. Travelers who need more data can choose from high‑volume fixed plans such as the 50 GB eSIM Data For 7 Days plan, which provides a 50 GB allowance over seven days, or from the 5 GB/day plans that run for up to 30 days. Because data is capped, the rate of data usage may trigger throttling after the limit is reached, so selecting a fixed data plan can often be more cost‑effective, especially for heavy users who stay longer in South Korea.
