# Create a Phone-only Event Type

> Switch a Cal ID event's primary confirmation channel from email to phone so bookings and reminders run through SMS-based workflows instead of email.

Switch a **Cal ID** event to a phone-first scheduling workflow by making a phone number — not email — the primary contact your booker must provide. It's ideal for SMS-based confirmations and reminders.

<Info>
  Selecting **Phone** in the Confirmation section makes the **Phone Number** field required and sets phone as the primary identifier for the booking.

## What happens on your booking page?

* **Primary requirement:** The **Phone Number** field becomes the mandatory input for guests to complete their booking.
* **Automatic formatting:** The phone field includes a country code selector to ensure international numbers are captured correctly.

<Tip>
  **Confirmation delivery:** Selecting the **Phone** option means meeting details are sent via SMS rather than a traditional email. This is perfect for high-touch services where clients are more likely to check their text messages than their inbox.
