Answer:
When IMS tries to send the SMS request to the SMSC but received a "Failed" status.
This indicated that the registered Mobile number is incorrect or invalid due to formatting.
Under the Delivery Log Details section, you can click on the "Authentication Request" in a blue box to view in detail.
