Does the app work without an internet connection (offline)?
Yes, the app has an offline mode specifically for your ticket. For this to work, you need to load your valid ticket at least once while you have a stable internet connection (e.g. at home at the beginning of the month).
Once it has been loaded, you can open the app and display your ticket at any time (by tapping the QR code icon), even if you are in an area with no reception.
Important: All other app functions are not available offline. You need an internet connection to manage your subscription, pause your ticket, change your profile data, or redeem your mobility vouchers.
