ByteSIM does not provide a truly unlimited high‑speed data eSIM for Austria. The plans labelled “Austria Unlimited Data” in the catalogue actually offer 1 GB of data per day, after which the speed is throttled to 10 000 kbps, so the data is capped. Travelers looking for larger data allowances can choose fixed data plans instead, such as the 50 GB options that run for 3 to 15 days, or the 30‑day plan that gives 1 GB each day at full speed before the reduced‑speed threshold is reached. These fixed‑data plans provide a higher total data volume for a set period, which can be more cost‑effective for most travelers.
