The DeliveryState property of a *sent* SMS will always be MM_SMS_DELIVERY_STATE_UNKNOWN (0x100). > Apart from the exact DeliveryState, I wonder if the callback trigger > confirms a successful delivery to the SMSC already? > No. When you send an SMS, the callback trigger confirms the SMS has been sent only (as reported by the modem) The way it works is like this: * You send an SMS with delivery-report-request=TRUE * While you do that, the "message reference" of the sent SMS will be updated to the correct one. * Once the SMS is received in the SMSC, the network will send you a new SMS. * You receive a new SMS (pdu-type: status report) with a message reference matching the one of your sent SMS. * The received SMS contains the information of the delivery in the DeliveryState property.
