hello,
when i am sending sms to ec200u-cn module i cant receive automatically SMS if run AT+CMGL=“ALL” this command then i get, but without run command also we get notification or receive SMS

AT+CMGL="ALL" is a text-mode command. What mode does AT+CMGF? say you are in?

That’s PDU-mode. The list command for that is AT+CMGL=4

AT+CMGF=1 will put the modem into text-mode, where AT+CMGL="ALL" is correct.

Quectel EC20 LTE Module doesnt show me incoming call or sms( notification)
if i execute AT+CMGL="ALL" this command i can see all incomming sms but i need to see automatically sms

Do you want them to appear as unsolicited results as they arrive ?

What does AT+CNMI? return?
