Absolutely. An active mobile data connection via CoreESIM is essential for managing your rail travel with ÖBB (Austrian Federal Railways) in Austria. The official ÖBB Scotty app, which is the primary tool for purchasing, displaying, and validating digital tickets, requires internet access. Without it, you cannot retrieve your tickets, check real-time schedules, or receive critical service updates. This connectivity is vital for hassle-free journeys between cities like Vienna, Salzburg, or Innsbruck.
