Zwitchy does not provide a truly unlimited data eSIM for Austria. The plans that carry the word “Unlimited” give a daily data allowance of 5GB for the specified validity period, and once that daily limit is reached the speed is reduced to 1000kbps.
Travelers who need more data can choose fixed‑data plans instead. For example, Zwitchy offers a 50GB plan valid for 30 days and a 30GB plan also valid for 30 days, both of which provide a larger total data allowance without the speed reduction that applies to the “Unlimited” plans.
