Great! If your Twilio Account SID, Auth Token, and phone number are correct, the issue might be due to one of the following reasons:
1. The credentials might not have been entered correctly. Please double-check that there are no extra spaces, typos, or incorrect case usage.
2. The Twilio account or phone number may not be active. Verify that your Twilio account is in good standing and that the phone number is properly set up in your Twilio dashboard.
3. There could be a temporary issue with the Twilio API service. Check Twilio's status page to see if there are any ongoing incidents.
If everything seems to be in order and you're still facing the issue, it might be best to reach out to Twilio's support for further assistance. They can provide more detailed insights into the error you're encountering.
