+CNMA, New Message Acknowledgment
This command acknowledges the receipt of a +CMT response from the terminal to the g20. It confirms the correct reception of
a new SMS-DELIVER message, which was routed directly to the terminal. When the g20 sends a +CMT response to the
terminal, it waits a predefined timeout of 60 seconds for the +CNMA acknowledgment. The g20 will not send another +CMT
result code to the terminal before the previous one is acknowledged, or the timeout expires. Upon receipt of the +CNMA
command, the g20 sends RP-ACK to the network.
If the g20 does not receive acknowledgment within the required time, it sends RP-ERROR to the network. The g20
automatically disables routing to the terminal by setting both <mt> and <ds> values of +CNMI to zero.
If the command is executed but no acknowledgment is expected, or some other g20 related error occurs, the final result code
+CMS ERROR: <err> is returned.
