SUMMARY
When an acknowledgement (ACK response) is received as a response to Short Message Service notification, it implies that the notification was delivered to the carrier Short Message Service center. It does not imply that the notification was delivered to the wireless device.

The Short Message Service center typically uses store and forward functionality to deliver the message to the wireless device.

If the Short Message Service center received the notification, but did not deliver it to the mobile device, it may be because the notification timed out on the Short Message Service center or because the short message memory on the wireless device was full and the Short Message Service notification could not be stored.



MORE INFORMATION
The message processor in Mobile Information Server Carrier Edition sends the request to the Short Message Service Connector, which uses a physical channel to forward the notification to the Short Message Service center. When an acknowledgement is received from the Short Message Service center, it is forwarded to the message processor.
