Sent Status signifies the journey of message from Salesforce to SMS Magic server. Whenever a outgoing History record is created, the initial value of SentStatus is ‘Submitted’ that means the record is forwarded to SMS Magic servers.

On the other hand, Delivery Status gives the real time delivery of the outgoing message. Once the record is created at SMS Magic servers, it pushed to provider’s end for further processing. As soon as we receive the delivery report from the provider the SentStatus is updated to ‘Success’ and Delivery Status to the one shared by the provider.
