KC868-A8M SIM7600 GPRS Disconnected

[deepthasm]

Hi,
Recently I bought KC868-A8M with SIM7600 module and Installed the latest KCS firmware (KCS_KC868_A8M_V2.1.9). I enabled the GSM on the network settings page. But, I'm getting "GPRS : disconnected" on monitor page. Try to clicking "Phone test" but I'm getting "error".

Following are the logs for reference.

So on, 

I checked SIM7600 module connecting directly to the Computer using USB. Module is working perfectly and can send and receive both SMS and Voice call.


Please help.
