Hi,

The "7" at the end of the CEREG output, indicates that you are on M1, and not NB1.

Can you reset your device, ensure that you see "AT Host sample started" then issue this:

AT%XSYSTEMMODE=0,1,0,0
AT+CFUN=0

Then you can reset the board again. The AT+CFUN=0 will store current settings, so you do not need to set NB1 directly on this board again.

Kind regards,

Håkon
