nadanada does not provide an unlimited data eSIM for Austria. The available options are fixed data plans that must be used within a set validity period. For example, a 100GB plan for 30 days costs $51.99 USD, and a 50GB plan for 30 days costs $26.99 USD. Both plans offer high data allowances for a month and are the largest bundles currently available for Austria.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data user who would benefit from a pay‑as‑you‑go model. The 20GB plan for 30 days at $11.99 USD provides a lower‑priced alternative for lighter usage, while still giving you a substantial amount of data for your stay in Austria.
