+CNMI - New Message Indications To Terminal Equipment
TEST MESSAGE
Note
DTR signal is ignored, hence the indication is sent even if the DTE is inactive ( DTR
signal is Low). In this case the unsolicited result code may be lost so if MODULE
remains active while DTE is not, at DTE startup is suggested to check whether new
messages have reached the device meanwhile with command AT+CMGL=0 that lists
the new messages received.
List Messages - +CMGL
+CMGL - List Messages
AT+CMGL=
