Since Calenso version 4.9.0 it is possible that customers have to verify their mobile phone number via SMS code before booking. This is a step to counteract fake bookings.


Activate functionality


Go to https://dashboard.calenso.com/app/settings/widget and enable the feature "Customers must verify their mobile phone number via SMS before they can make a booking". Once the feature is enabled, customers will be prompted to verify their phone number once when making a booking. Once the phone number is verified, it will not need to be verified again when making another booking.


Please note: As a partner, you will be responsible for the SMS cost of 10 centimes per SMS. Calenso will invoice the costs at the end of the year.

Now enter the code in the code field:



After that click on "Verify". If the code is correct, then the phone number is verified:



If the code is not correct, then the following message will be displayed:



The code can be requested a maximum of 3 times. If it still does not work, then Calenso Support must be contacted at support@calenso.com.
