Jetpac does not provide a truly unlimited data eSIM for Austria. All plans that carry “Unlimited” in the name give 3GB of high‑speed data per day; once that daily allowance is reached the speed is throttled to 1024 kbps, so the data is not unlimited.
Jetpac offers fixed‑data plans instead, such as Global 50GB valid for 365 days, Europe 40GB valid for 30 days, and Global 30GB valid for 30 days. These plans deliver a set amount of high‑speed data and may be more cost‑effective for travelers who need a larger overall data allowance.
