Test Network (Forbidden)

I am using Quectel RM500Q_VH to connect to a private 5G test network from windows 10 machine. The simcard is programmed perfectly and can connect from my mobile phone to the USRP but when I use Quectel Modem I get this network is forbidden.

Can you please explain why I am getting this? Is there a way around it?


Dear Brahim,
Nice to know you.
First, please send ATI/AT+CGATT?AT+COPS?AT+QENG=“servingcell” to check if the module have registered the network. In addition, the firmware of the module is quite old, please get the latest sample from our sales or distributors.
