Sending short message service (SMS) messages and receiving a response report based at least in part on the sent SMS message, even if a communicative connection with the mobile communications network had been severed, so that duplication of the SMS message is avoided is disclosed. In this case, a communicative connection may be re-established and used to receive an acknowledgment from the mobile communications network and subsequently send another acknowledgement to the mobile communications network. The UE may also be configured to send an information element to the one or more elements of the mobile communications network to indicate that a communicative connection with the network is to remain established so that acknowledgements may be reconciled between the UE and the network. Additionally, the mobile communications network may be configured to transmit the SMS message only after receiving the acknowledgement from the UE, to avoid sending duplicate SMS messages.
