# Customize Phone Templates

> Customize the appearance and content of phone messages sent by Auth0's phone-based workflows using phone templates.

<Warning>
  To customize phone templates, you must [configure an external phone provider](../configure-phone-messaging-providers).
</Warning>

## Customize phone templates

To customize a phone template:

1. Go to [**Dashboard > Branding > Phone Templates**](https://manage.auth0.com/#/phone).

2. From the **Template** dropdown, select the phone template you want to update.

3. Toggle the **Status** slider to enable the tempate if it isn't already enabled.

4. Update the **From** phone number and/or the **Text Message Template**.

5. Select **Save** to save your changes, **Try** to test your changes, or **Reset** to revert your changes.

### From phone number

<Warning>
  If you're using [Twilio Messaging Services](https://www.twilio.com/docs/messaging/services) as your SMS source, you cannot set a custom **From** phone number. Instead, Twilio chooses a number from your Messaging Service's sender pool based on your Twilio configuration.
</Warning>

The **From** field sets the phone number that text messages are sent from. The default **From** phone number is the one you set when you configured your phone provider.

To set a custom **From** phone number for a phone template, enter the phone number in this field.

### Text Message Template

The **Text Message Template** field sets the content of the of the text message. Each template comes with a default message body which you can modify or discard entirely to write your own.

This field supports Liquid syntax for dynamically generated content. To learn more, read [Supported Liquid Syntax for Phone Templates](./supported-liquid-syntax).

## Test updated templates

To test a phone template, click **Try**. Auth0 sends the phone message to a default app named after your tenant name. To test templates for different applications, create a sample user to go through the phone message flows.

You can trigger verification emails manually for specific applications and users using the Management API [Send an email address verification email](https://auth0.com/docs/api/management/v2#!/Jobs/post_verification_email) endpoint.
