9.11. AT+CNMA New Message Acknowledgement to UE/TE
AT+CNMA write and execute command confirms successful receipt of a new message (SMS-DELIVER or
SMS-STATUS-REPORT) routed directly to the TE. If the UE does not receive acknowledgement within
the required time (net-work timeout), then it will send a "RP-ERROR" message to the network. The UE
will automatically disable rout to the TE by setting both <mt> and <ds> values of AT+CNMI to 0.
