If you use the SMS notification for your online booking, costs will be incurred.
The SMS costs are billed retrospectively every month (CHF 0.10 per SMS part, for more information on the SMS parts, see example below).
As a rule, 2 SMS are sent for an online booking confirmation and 1 SMS for the online booking reminder. So 3 SMS are sent for each online booking.
Example of invoice: 3 SMS x CHF 0.10 = CHF 0.30. The SMS are charged per SMS part.
