What do you mean by ‘disable and reactivate the SIM card’? How are you doing that?
The issue I was having was some task (I suspect lwip) gets messed up. Stopping the modem, trying to connect wifi, etc, all just locked up the async console. I think you had the same?
Cellular connectivity should be a different issue. Maybe just can’t connect to the signal - but the logs should tell us more info. We can also directly issue AT commands when the modem is in that state to try to find out why.

I’m trying to keep things simple, to get a base system stable first, before adding more complexity, so I just have a ovms server v2, a wifi scanning client (connecting to any available access point), and a simcom modem running. That seems stable for the past two days for me.

This doesn't freeze the whole system when I power off the simcom so it may be we have two bugs. I don't have the right simcards here so I'll try it on Monday.
