5G Network Not Detected with 5G SIM in RG500Q

Hi,

I’m experiencing an issue with my RG500Q router when trying to use a 5G SIM. Here’s the situation:

Without the SIM inserted, the router can list the available networks, including the 5G network. However, after inserting the SIM, the 5G network is no longer listed.

Logs:

Without SIM inserted:

AT+COPS=?
+COPS: (1,“IND airtel”,“airtel”,“40445”,7),(1,“IND-JIO”,“JIO”,“405861”,12),(1,“Vi India”,“Vi India”,“40486”,7),(1,“CellOne”,“CellOne”,“40471”,2),(1,“Reliance”,“Reliance”,“40510”,7),(1,“IND-JIO”,“JIO”,“405861”,7),(0-4),(0-2)

With SIM inserted:

AT+COPS=?
+COPS: (1,“IND-JIO”,“JIO”,“405861”,7),(3,“Reliance”,“Reliance”,“40510”,7),(3,“CellOne”,“CellOne”,“40471”,2),(3,“IND airtel”,“airtel”,“40445”,7),(3,“Vi India”,“Vi India”,“40486”,7),(0-4),(0-2)

As you can see, the availability of the 5G network changes once the SIM is inserted. I’ve confirmed that my SIM supports 5G.
Has anyone encountered this issue before or have any ideas on what might be causing this? Any help or suggestions would be greatly appreciated!

Thank you!

Dear @gopi
Could this device register on 5G with this 5G SIM card?
Please share your current firmware.

Thank you for your response.

The device is currently unable to register on 5G with the 5G SIM card. The firmware version I’m using is RG500QEAAAR11A02M4G_OCPU_01.001.01.001.

Please let me know if there are any steps I can take or if a firmware update might help resolve this issue.
