iRoamly does not provide an unlimited data eSIM plan for Austria. All of its offerings for Austria have a hard data cap, with the largest bundle being 90GB valid for 365 days and smaller bundles such as 50GB for 3 or 5 days.
If you need a high‑volume option, the 90GB 365‑day plan or the 50GB 5‑day plan are examples of the fixed data plans available. These fixed‑data bundles can be more cost‑effective for heavy data users, while paying‑as‑you‑go options allow you to top up your balance if you anticipate using more than the cap.
