I've received a Nordic Semiconductor nRF9161 from a friend, who has been using it for a while.
I would like to completely reset the module, as it came when bought, so I can begin with the beginner guides and learn.
How do I do that?
When I try the Cellular Monitor it currently fails with:
07:37:09.456
AT command AT+CPIN? failed: +CME ERROR
07:37:09.473

07:37:20.582
AT command AT+CPINR="SIM PUK2" failed: : 0 +CME ERROR
I've tried with several SIMs and every time it is the same. However, the SIMs work in a regular phone and they do have access to LTE-M.
So, I think it would be best to reset the entire device.
