Hello Ibrahimsahebi
In my opinion, whenever possible, you should pay it in a one-off payment as there is, compared to the total amount due, a high administration fee for instalments.
You can find the information provided below on this website: https://www.sbb.ch/en/help-and-contact/my-travelcards/travel-without-valid-ticket.html#anchor5
You should note the following conditions:
- Minimum monthly instalment: CHF 40
- There is a one-off fee of CHF 40 for the instalment agreement (administrative expenses).
- Maximum number of monthly instalments: 24
Are you interested, and can you meet these conditions? If yes, then please complete the following form:
