12.11 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. If ME does not receive acknowledgement within required time (network timeout),
it will send RP-ERROR to the network. In this case routing to the TE will be disabled automatically by setting
both and values of AT+CNMI to zero.
