Do we need data for OBB train tickets in Austria when traveling with Triply?

Yes, having mobile data from Triply is essential for managing your train tickets when exploring Austria with your friends. The national rail service, ÖBB, primarily uses digital tickets, which you'll need to purchase and display on the ÖBB Scotty app. A stable connection ensures everyone in your group can access their tickets seamlessly, check train times, and avoid any last-minute stress or potential fines while traveling between cities like Vienna, Salzburg, or Innsbruck.
