eSIM Firsty pour Austria en 2026

Firsty has not published which operators it uses in Austria, so the radio side is unknown rather than a sign of poor coverage; the table above is where the practical plan details can be checked. Its large range makes sizing the real decision, with the risk of buying more data than a fortnight needs. Firsty lists technology up to 5G, but does not say whether voice is available. Top-up is stated as supported, so an exhausted plan can be extended rather than necessarily rebought.
