Hello,
I keep experiencing this issue where the hat on my RPI will not connect to the internet whatsoever, even though its reporting “0,5” on CREG.
The unit also disconnects and reconnects from my Pi in in 15~s intervals.

If you have any ideas, please let me know.
It’s plugged into a Raspberry PI 4, running the latest version of Raspbian with a Sixfab SIM.
I’ve frankly sunk over 10 hrs into this thing and am incredibly frustrated. There is no logic behind it, it sometimes connects if I plug it into a windows machine and use the windows drivers.
Thanks,
Max
