Write Command:
Write Response:
The execute / write command shall only be used when AT+CSMS parameter <service> equals 1 (= phase
2+) and appropriate URC has been issued by the module; i.e.:
<n>
0
1
2
<+CMT> for <mt>=2 incoming message classes 0,1,3 and none;
<+CMT> for <mt>=3 incoming message classes 0 and 3;
<+CDS> for <ds>=1.
Meaning
SMS service of ME reserved
Operation not allowed
Operation not supported
Invalid mode parameter
Invalid text mode parameter
SIM failure
Invalid memory index
SIM or modem memory full
SC address unknown
no +CNMA acknowledgement expected
The write / execute command confirms successful receipt of a new message (SMS-
DELIVER or SMS-STATUS-REPORT) routed directly to the TE. If ME does not receive
acknowledgment 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.
Parameter required only for PDU mode.
Command operates similarly as in text mode.
Send positive (RP-ACK) acknowledgement to the network. Accepted only in PDU mode.
Send negative (RP-ERROR) acknowledgement to the network. Accepted only in PDU
mode.
