nRF9160 NB-IoT SIM registration step by step guide

[5prinG]

hi 

I have nRF9160 dev kit, which I am using in a LAB with a private LTE SIM card, which has 99920 PLMN ID.

The network supports Band 3, and NB-IoT is configured as an in-band signalling.

I am using nRF connect 3.6.1 software to fire up the AT commands, which includes scanning of the network, and then it should allow me to register to the network

which is not happening, 

at this stage, can you please provide me step by step AT command guide to troubleshoot the problem, 

I am attaching the initial device logs collected, 

Moreover, I have also tried with the Vodafone commercial SIM card, which is also not connecting.

I am using this kit with a windows 10 machine, 

looking foward

hi Markus

i made those changes, but device is still not registering to the network

I have attached the device logs here, 

could you please point out if device is successfully scanning the NB-IoT cell, PLMN 99920, 

I am within the vicinity of the antenna, it is an indoor set up, 

We have Nokia radios, 

We are troubleshooting with Nokia, and at the moment Nokia is claiming that device is not requesting for the registration on NB-IoT,

We have deployed it on B3 inband singnalling, 

Nokia also claims that they have successfully used this device in the lab, so do I am trying here in my set up.

I really appreciate your time here, 

We can discuss it over the phone if you would like, so I can give you some more background .

If we can rule out that device is configured correctly for B3 inband NB-IoT, and it is sending the registration request, with the evidences from the device log, then we are in a good position,
