For all the people following this project, deadline is on my head and I can not make this modem connects with the network, I made the last try and the answer is negative, the project are moving with or without the contest.

wait for the news...

I've most of the parts here, even the modem. We have NB-IoT coverage in Germany - at least in some cities. I've running setups here with the BC68 and I would rebuild your tracker but your chosen microcontroller is unknown and uninteresting for me. Anyway, if you do need any parallel testing, let me know.

I have been using this microcontroller for some years and I choose it because is very small and has the periferics that I need for the project, I'm very interested on make some parallel testing, thank you for interest and ur help.

Which commands did you use to initialize the NB1 modem? Your screenshots just show the CEREG command.

Quectel has some examples in the AT-commands guide, you may want to look into it.

Yes, I know how to initialize the modem correctly, my problem was that I did not get an appropriate simcard, in Mexico the NB-IoT network does not work, and in the USA only T-Mobile has this network, and the simcard that I had welded on my device has contracted with all network operators in the USA less with T-Mobile, I already explained in the logs that try to solder a normal simcard but during the process I make some mistake because the modem stopped working.
I already replaced the modem and started to work correctly but the problem that I am not in the USA to continue with the tests, by the way I found a small error in the hardware so I think to make a second version of the card and retest it in USA
