mobineX does not provide any plan with truly unlimited high‑speed data for South Korea. All mobineX itineraries list a specific data cap, such as 1 GB, 5 GB, 28 GB, 42 GB, 52 GB, 65 GB, or 100 GB, and even plans titled “Unlimited” reduce speed after the limit is reached. Travelers who need a large amount of data can choose from fixed‑data options—for example, the Unlimited – 7 Days plan offers 52 GB over 7 days, the Unlimited – 30 Days plan gives 65 GB over 30 days, or the 100 GB – 60 days plan supplies 100 GB for 60 days. These fixed‑data plans may be more cost‑effective for users with heavy data demands.
