Why is undelivered SMS charged?

When a message is sent successfully from our platform but is not received at the end user's handset, we're already charged by the carrier. Therefore, you will be charged for a message if delivery is attempted, i.e., the message status is "sent," "delivered," "undelivered," or "delivery unknown."
