One common issue developers encounter while using Plivo is the 'Message Delivery Failed' error. This symptom is observed when a message sent through the Plivo API does not reach the intended recipient, resulting in failed communication attempts.

Exploring the Issue: Why Does Message Delivery Fail?

The 'Message Delivery Failed' error typically occurs when there is an issue with the recipient's phone number.

Confirm that the recipient's phone number is active and capable of receiving SMS messages. You can do this by contacting the recipient or using a phone number validation service.

Step 3: Review Plivo API Logs
