2. **Add** to your page the **element** you'd like to trigger the SMS;

It can be a button element, an image element, or a text element (in this example we'll use a button element).

3. In the **"Styles"** tab, find the **"Link"** field and select the **"External link"** option;

4. Next, enter your contact number **exactly** in this format -> sms:51999999999 and **refresh the page**;

||| The external link field is a field specifically for links, which means the **"URL informada inválida"** message will appear when you enter your contact number, but don't worry, it will still work this way.

5. After the **page** is **published**, click the button element and the SMS to the contact number you entered will appear.
