Use AT commands

The LTE stick can also be configured using AT commands via a tool such as PuTTY. The listing of the lower
AT commands is not comprehensive and is limited to the most important commands.
Check whether the SIM card is already unlocked:
AT+CPIN?
Output:
+CPIN: SIM PIN Card is still locked.
+CPIN: READY Card is no longer locked.
Enter the PIN if the SIM card still needs to be unlocked:
AT+CPIN=<your pin>
If the SIM card is unlocked, the PIN request can be deactivated by the following command:
AT+CLCK="SC",0,"<your pin>"
To reactivate the PIN request after a reboot of the stick:
AT+CLCK="SC",1,"<your pin>"
Assign a new PIN:
AT+CPWD="SC","<pin old>","<pin new>"
Show APNs already registered on the stick:
at +cgdcont?
Output:
+CGDCONT:
1,"IPV4V6","internet.telekom","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT:
2,"IPV4V6","internet.beckhoff","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
Enter new APNs:
at+cgdcont= Index(max24),"IP","your apn"
Example:
at+cgdcont=1,"IPV4V6","internet.telekom"
Delete APN:
at+cgdcont=<select Index>
