To share design info more freely, I recreated this case as private. This public case can be closed.

It's a socket modem that only supports LTE and GPS, so there are no other radios on the device.

We had a prior nRF9151 designs reviewed by Nordic (which this design heavily relied upon). But this design was probably not reviewed by Nordic.

I can share the schematic. Is there a way I can send it directly to you and not post it in a public case?

Hi,

Are there any other radios on the device?

Have you had the design reviewed by us ?

Could you share the schematic or the parts related to GPS\LTE?

Regards,
Jonathan
