How do we know if messages have been successfully delivered?

Live Link 365 uses standard SMS Delivery Acknowledgments (Acks). Delivery Notifications are message acknowledgments sent from our network to customers. When delivering messages through our network, customers can request to receive the following three levels of acknowledgment:

 

  • Ack
  • SMS-C Ack
  • Handset Ack.

For unsuccessful delivery attempts,  a negative acknowledgment (Nack) is returned, which outlines the reason for the failure. Some Operators might not support mobile / handset acks, which means SMSC ack will be the final acknowledgement.
