The delivery report statuses track the following conditions:
1. Pending: This means the message has not yet left the messaging system and has not been forwarded to the communication company for delivery.
2. In Delivery: This indicates that the message has left the messaging system and is in the process of being delivered to the recipient's number.
3. Delivered: This means the message has successfully reached the recipient's number, and the report displays the date and time of delivery.
4. Not Delivered: There are two scenarios for the "Not Delivered" status:
- First: This occurs when the number the message was sent to is invalid or does not exist.
- Second: This occurs when 24 hours have passed since sending the message, and it has not been received by the recipient.
In both of the above cases, the messaging system automatically refunds the credits used for sending the message back to your account. The messaging system also provides the reason for non-delivery to clarify the possible causes. This helps verify the accuracy of recipient numbers and ensures successful message delivery.
