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.
