Question

Why could this SMS not be delivered?

Answer

There are many reasons why an individual SMS could not be delivered.

If the delivery state of the SMS is not self-explanatory, simply hover over its delivery state using the Broadcast Analysis extension or the Delivery Reports page. This will then reveal a more detailed explanation (if available) as to why the SMS could not be delivered.
