Roaming4You does not provide a true unlimited data eSIM for Austria. All of its Austria plans list a fixed data allowance—1GB per day or 1GB for the entire validity period—regardless of the name “Unlimited.” After the allotted amount is used, the speed would typically be throttled, but the plan itself is not unlimited. Travelers who need a large amount of data can instead choose one of the fixed‑data plans. For instance, the Austria Unlimited Data – 10 days plan offers 10 GB of high‑speed data for $10.00 USD, and the Austria Unlimited Data – 30 days plan provides 30 GB for $30.00 USD. Both plans are fixed‑data bundles that remain usable until the designated validity expires.
