@Franklin Workman Thank you for reaching out to Microsoft Q&A. Apologize for the inconvenience caused on this.
Based on the shared information we have understood that when you are trying to send the SMS, they are not getting delivered to end recipient but in command terminal it is showing as message sent successfully.
What is the http status code you are seeing when you send a message? if it is 202 as mentioned in this documentation If 202 is returned by the service means that your message has been queued to be sent and not delivered. Use this quickstart to subscribe to delivery report events and troubleshoot. Once the events are configured, inspect the "deliveryStatus" field of your delivery report to verify delivery success/failure.
Feel free to reach back to me if you have any further questions on this.
