Hi Richard,

First, let's verify that you get a connection with the network by running a precompiled application found here.

Select which network version that suits you, nb-iot or LTE-M.

And follow the testing steps so that you have paired your device with nRF Cloud.

Note: the application running on the nrf52 does not support out of the box. You need to flash another application to make that happen.

Since you are trying to run LTE Sensor Gateway you need to follow these instructions to make it run on Thingy:91.

Best regards,
