> 13.10 | AT+CNMA New Message Acknowledgement to ME/TE, only phase 2+

> The write / execute command confirms successful receipt of a new message (SMS-DELIVER or SMS-STATUS-REPORT) routed directly to the TE. TA shall not send another +CMT or +CDS result code to TE until previous one is acknowledged. If ME does not receive acknowledgement within required time (network time-out), ME sends RP-ERROR to the network. TA shall automatically disable routing to TE by setting both <mt> and <ds> values of AT+CNMI to zero.

> Notes

> • | The execute / write command shall only be used when AT+CSMS parameter <service> equals 1 (= phase 2+).

> • | The execute command can be used no matter whether text mode or PDU mode is activated. The write command is designed for the PDU mode only.

> • | If multiplex mode is activated (AT+CMUX=0) the AT+CNMI parameter will be set to zero on all channels, if one channel fails to acknowledge an incoming message within the required time.
