eSIM Roamless pour Austria en 2026

A1 net is the sole network Roamless lists for Austria, so the radio choice is settled before you choose a plan: the differences here are allowance and validity, not a second named operator. Roamless lists 5G as its fastest technology, a ceiling rather than a promise for every connection. Its catalogue covers a large range, making data sizing the main decision—and the risk is buying more data than a fortnight needs. Top-up is available, so an exhausted plan can be extended; Roamless does not say where traffic breaks out.
