The board doesn't connect to my APN

[FlavioDiNuzzo]

I have the latest firmware in the modem (0.7.0-29.alpha) and i have the at client sample code on my board, I set my APN but the board doesn't connect

I'm sure that the APN is working because with another developement board from another producer I can connect with the same sim!

Thanks in advance for the help,

Kind Regards

Hello, 

Have you configured the modem as NB-IoT? Can you please issue the AT command: AT%XSYSTEMMODE? (with ? on the end).
Example: 

AT%XSYSTEMMODE?
%XSYSTEMMODE: 1,0,0,0
OK

More information can be found in the AT Command Reference Guide. 

Kind regards,
Øyvind
