No, EZsim does not currently provide an unlimited data eSIM for Austria. Instead, EZsim sells fixed‑data plans such as a 50GB package valid for 90 days that costs $78.80 USD and a 20GB package valid for 30 days that costs $31.50 USD. These plans come with the same network coverage in Austria.
Because the plans are limited in data, a fixed‑data option is typically more cost‑effective for most travelers. An unlimited plan would be necessary only for very heavy data users, and such a plan is not available from EZsim in Austria at this time.
