Please make sure your phone is properly charged before you start your journey, as you will not be able to present your ticket or pass without a charged phone or an active internet connection, and the driver or staff may refuse you boarding or charge you a penalty fare.
If your phone was out of battery power, you can present your valid BKK ticket (which was valid during your journey) to BKK Customer Service within 5 working days. Details: https://bkk.hu/en/tickets-and-passes/information-about-penalty-fares/conditions-and-options-of-penalty-fare-payment/
Please bring the following with you to the “pass presentation” procedure:
- a valid mobile ticket
- a charged phone
- a valid photo ID card linked to your pass
