Hello,
Cellular command should be enabled by default. Also, it does not send a reply message about its execution, but it should be visible in the device logs with the CLI/SSH command logread.
What is the firmware version your device is running on?
You can also use UCI commands, to configure device settings. For example:
- <routers_passwd> uci set network.mob1s1a1.apn=<your_APN>
You should then receive a message about replaced value. Next, send the following message to write the setting to the router's flash:
- <routers_passwd> uci commit
You can read more about uci command usage here.
Best regards,
