I am using a BG96 (firmware: BG96MAR02A07M1G) and am unable to register with my local network operator. I have tested the Sim in another BG96 running the same firmware in the same location and I am able to connect just fine. Here is the output when I try to register:

It seems I have adequate signal strength and other BG96 IOT devices of same hardware configuration are able to connect easily. What could be causing this issue? What are some additional debugging steps I should go through to narrow down what could be going wrong?
Any help is appreciated thankyou!
