ETravelSim does not provide a truly unlimited high‑speed data eSIM for Austria. Every plan listed under Austria gives a fixed allowance of 4GB/day; once that amount is used, the connection is reduced to 128 kbps. The “Unlimited” label on the product name reflects this fixed daily allocation rather than an unconstrained data cap.
If a larger high‑speed data allocation is desired, ETravelSim offers fixed‑data plans, such as the 50 GB for 30 days plan priced at $49.99 USD. These plans may be more economical for travelers who need consistent performance without the speed reduction that applies after the daily 4 GB limit is reached.
