TRB500 5G not working with German Telekom SimCard

I’m not sure if I’m making a mistake.

My modem TRB500 does not show 5g (NSA).
I have a RUT50X next to it and it shows with 5G (NAS).

Both have the firmware 07.04.05 to match the device.

I queried the following in the console of the TRB500.

what could be the problem?
Thanks for the help


Thank you for providing the AT command output!
This seems to be the same issue as here: TRB500 no connection on 5G since update
It should be noted, that this is only a visual issue, and should not affect the performance of the device. Please reach out to your reseller, sales manager or fill out the Contact Us form here: Teltonika Networks - LTE Routers, Gateways & Modems for IoT and we will provide you with the instructions on how the modem can be updated. Thank you!
