Cellular unavailable on LE910C4-NF and Raspberry Pi

I’m attempting to get my Sixfab 4G/LTE Cellular Modem Kit for Raspberry Pi working but running into trouble. The dashboard says cellular is unavailable…

Hi,

+CGATT: 0 and +CREG: 0,2 indicate that the device is not connected to the cellular network. We have reset your SIM connection. Resetting your SIM’s network connection can often resolve general connectivity issues. This reset will terminate all active data sessions and force the SIM to reconnect to an available network.

Additionally, you can force it to re-register by using the following commands:

AT+COPS=0
AT+CREG=1
AT+CGATT=1

If the issue persists, you can enable remote support and send me your remote support-token via PM so I can check and fix it.
