Quick answer
For a trip involving Vienna, Salzburg, Innsbruck and Alpine destinations, the most reliable approach is to install your travel eSIM before departure, keep the QR and essential bookings offline, and switch mobile data to the eSIM when you need it after arrival. A rail itinerary can involve several stations and short connections, so mobile data is most useful for live logistics rather than constant streaming.
