Hello,
I would like to know which is the most correct procedure to set APN for TCP/IP contexts (Data) and for services such as VoLTE. I saw that APN can be set both with the AT + QICSGP command (APN with usr and pwd) and with the AT + CGDCONT command (APN without usr and pwd).
From some Tests, it occurs that using the AT+QICSGP command to set APN for the TCP/IP context, the APN parameter of the AT+CGDCONT command is also automatically set.
So the correct procedure for APN setting could be the following?
AT + CFUN = 0
AT + QICSGP = 1,1, “apn”, “username”, “password”, 3
AT + CFUN = 1
AT + QICSGP = 1
+QICSGP: 1, “apn”, “”, “”, 3
AT + CGDCONT?
+CGDCONT: 1, “IP”, “apn”, “0.0.0.0”, 0,0,0,0
+CGDCONT: 2, “IPV4V6”, “ims”, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”, 0,0,0,0
+CGDCONT: 3, “IPV4V6”, “”, “0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”, 0,0,0,1
