I have set the module to interact with the AT&T network. And the apn name to nxtgenphone and I have enabled the pdp entry but it still won’t connect to the network.
+CGDCONT: 1,“IPV4V6”,“nxtgenphone”,“”,0,0,0,0
+CSQ: 24,4
+CESQ: 99,99,255,255,20,49
+CREG: 0,1
+COPS: 0,0,“AT&T”,7
My goal is to be able to send and receive SMS messages.
I also seem to be receiving SMS’s maybe from the carrier?
+CMTI: “ME”,7
But when I try to read them I get +CMS ERROR: invalid memory index.
That message was recieved when I changed the apn name.
