EP handles success and failure responses from all SMSCs. The responses are made available to the application for further evaluation and processing. For no connectivity with the SMSC, the SMS processor issues retries. The number of retries is not configurable and retries are infinite. The retry interval is configurable.

Other than the connectivity with the SMSC, the application has the capability of handling failures. The application can trigger a Resend or any other action to address the failure.
