EM7455 - AT!SCACT=1,1 command shows error with no network service

[krishnadaskv]

I am currently trying to configure an EE IoT SIM to EM7455.
The AT+CGDCONT? command gives the following response.

+CGDCONT: 1,"IPV4V6","apn.com","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

OK

I am using a custom APN with username and password, while configuring using CGDCONT command I provided only APN url, I am not sure where to provide username and password.

But for AT+SCACT=1,1 command it shows an error

AT+SCACT=1,1
ERROR
AT!SCACT=1,1
+CME ERROR: no network service

You can see here for username amd password

AT command to setup username and password on EM7565

On EM7565, in case you need to setup a username, password and authentication to access a specific APN, you can easily setup those parameters using Linux SDK API or even Windows 10 GUI (Network & Internet > Cellular > Advanced Option > Add an APN). In case your only option is AT command, you can rely on non-documented command AT$QCPDPP. Syntax description can be found in the following document. https://source.sierrawireless.com/resources/airprime/minicard/2130616_ap_mcsl_umts_lte_extended_at_co…
