Avelis eSIM does not offer an unlimited data eSIM for South Korea. All of its South Korea plans have a hard data cap, with the largest caps being 50GB for a 30‑day or 180‑day validity and 20GB for a 30‑day validity.
Travelers can choose from several fixed data plans such as the Standard 50GB / 30 Days plan or the Standard 50GB / 180 Days plan, both providing 5G coverage and tethering allowed. These plans are often more cost‑effective for typical users, while heavy data consumers may find a larger or longer‑validity plan more suitable.
