+   - In your backend code, use the Twilio SDK to send SMS notifications.
+   - Initialize Twilio with your Account SID and Auth Token.
+   - Use the purchased phone number as the sender and your users' phone numbers as recipients.
+   - Craft a message containing the notification details, such as product expiry date, and send it using Twilio's API.
+
+6. **Test SMS Notifications**
+   - Test the integration by triggering SMS notifications in your application. Ensure that users receive the notifications correctly.
+
+7. **Handle Errors and Edge Cases**
+   - Implement error handling for cases such as failed SMS delivery or invalid phone numbers.

+
+10. **Final Testing and Deployment**
