Hi…may be gadget in not associated with the cell network as the cm radio order tells.

Your module is LTE-M/NB-IoT and 2G, however it seems like you constrained it into 2G mode.

You can change the RAT with the order cm radio rodent LTE for LTE or cm radio rodent AUTO for the programmed mode, and so on

The SIM in your module isn’t a Sierra Wireless SIM. It may not be an issue however. Yet, the first SIM that was given this mangOH Red and related with your gadget on AirVantage isn’t this one.
