MobineX does not provide a true unlimited high‑speed data eSIM for Serbia; all plans listed have a fixed data cap. The term “Unlimited” refers to the plan name, but once the specified amount is consumed the network speed is reduced. For example, a “Unlimited - 7 Days” plan offers 52GB of high‑speed data, after which the speed is throttled.
Travelers who want a large amount of data can choose a fixed‑data plan instead. Options such as 100GB for 60 days or 150GB for 90 days provide more data without the speed reduction that comes after the cap, and may be more cost‑effective for heavy users.
