Create a Phone-only Event Type

In Cal ID, switch an event to phone-first so guests confirm with a phone number and get details by SMS — ideal for SMS-based workflows.


Switch to phone confirmation


  1. Open Event Types and click Edit on the event.
  2. Go to the Booking questions section.
  3. Under the Confirmation header, on the right you'll see an Email / Phone toggle.



  1. Click Phone — this makes the Phone Number question required.
  2. Click Save.


What the booker sees


The Phone Number field becomes mandatory, with a country-code selector for international numbers.



💡 Tip


With Phone selected, meeting details are sent by SMS instead of email — great for clients who check texts more than their inbox.
