How to control customer opt-in at checkout ?

This process sets up a workflow where customers must explicitly choose to receive SMS updates, ensuring compliance and valid data collection.

1. Go to WooCommerce → SMS Settings.
2. Enable the workflow that requires customers to opt in to SMS notifications during checkout.
3. Decide whether the opt-in checkbox should be pre-selected or require manual confirmation.
4. Customize the opt-in label so customers understand what they are agreeing to.
5. Choose where the opt-in option appears on the checkout page.
6. If you are using supported providers (such as Vonage or Twilio), enable phone number validation so incorrect numbers are blocked during checkout.
7. Save your changes.
