Switching COPS mode while registerd to a network | Telit Cinterion IoT Developer Community

I have a question regarding the AHS3-W:

The modem is configured for automatic operator selection AT+COPS=0

There can be situations where the modem is registered to a roaming network PLMN1 and we want to force the modem to register to another roaming network PLMN2.

I can do this by deregistering using AT+COPS=2 and using manual registration AT+COPS=1,2,"PLMN2"

After the modem has registered to the new roaming network PLMN2, the modem is now in manual operator mode.

At this time I like to bring the modem back to automatic mode WITHOUT deregistration of the network PLMN2 that I have selected manually.

If I would use AT+COPS=0, would the modem remain in PLMN2 or would AT+COPS=0 force the modem to register to another network which could be PLMN1 again?

If it would go back to PLMN1, would there be any other way to stay registered in PLMN2 but have automatic mode turned on so that automatic network selection takes place as soon as PLMN2 gets lost?
