mobineX does not offer a truly unlimited data eSIM for South Korea. Every plan marked “Unlimited” in the mobineX catalogue has a specified data cap. For instance, the 65GB plans valid for 10, 15 or 30 days provide only 65GB of high‑speed data before the connection speed drops, and several 1‑day plans are capped at 1GB with speeds reduced to 128kbps after the limit is reached.
Travelers who need a larger data allowance can consider fixed‑data alternatives, such as the 100GB plan that is valid for 60 days. Fixed‑data plans often give a higher total amount of data at a predictable cost and can be more economical for users who consume large amounts of data.
