Hi,
I am a developer of IoT systems working for a private firm within Africa. I currently started the development of a cellular IoT solution and my search landed me on the Nordic's nRF9160 which is specified with LTE-M and NB-IoT which i find useful for my project. Though i am curious about a few things before i recommend this to the development team as a solution;
1. Is it possible to use a custom IoT instead of nRF Cloud?
2. Does nRF9160 chips come with its IMEI for the SIM?
3. Can i use any LTE 4G enabled SIM instead of iBASIS or HOLOGRAM and the likes?
4.
