Hello Peter,

it seems like the modem is not able to find a network cell which it can connect to. Does the modem find any available network at all? You can check this by using +COPS/%COPS.

Are you facing this behaviour in NCS v1.9.0 only? Or does the modem operate as expected with earlier versions?

Regards,

Markus

Hi Albrecht Markus Schellenberger,

This module requires the following instructions specially configured

AT%XSYSTEMMODE=0,1,0,0

Thank you very much.
Kind regards,
