SIM type identification

Hello,

Is there any specific AT command for BG95&BG96 chips to identify the type of SIM connected to the chip? We are using GSM and NB-IoT SIMs and I would like to identify the SIM type before executing network scanning.

Many thanks,

it is not operational ,like this

but if your sim card provisiion is GSM only , the module will not scan NB automaticlly
