Connecting to rak7243c to Bell network

I’m quite new guy on lorawan technology. I bought a RAK7243c. It’s working fine but since the beggining but I want to use the LTE modem, On the modem lights are all lighting but it seems to have problem reading the script. Any idea what is the problem…
Thanks for your help

Try the following steps to get some more detailed information.
1.Use sudo gateway-config disable lte module.
2.Restart gateway.
3.Use sudo minicom -D /dev/ttyAMA0 -b 115200 to connect to the lte module.
4.Enter at+cops=? to check if there is any carrier information of your SIM card in the printed content.
