Aha! Solved it!
Tl;DR: it seems it was an unsent SMS sticking around in /var/lib/ofono
Background: That SIM is a prepaid one.
After buying it, you have to
- Register it/verify yourself on some website (legal requirement)
- Top up the prepaid amount (starts with 0)
- Select a data/voice plan (switching away from the default plan). Which can among other options can be done by sending SMS to some internal short number.
While 1. and/or 2. has not been done, one can receive SMS from the provider, and do some things like dial *#101# to check the prepaid balance.
Just for kicks I tried sending the “Select plan” SMS twice, and some to another phone number of mine.
These messages were either in “Failed”, or in “Sending” state when I rebooted, and this is the pointthe Ofono crashes began.
After I did the below and rebooted, ofono crashes are gone,
Not sure which one of the files was the reason, but it seems fixed now.
Probably it’s the tx_queue thing, and the other ones wouldn’t have been necessary, too late to check now.

. So no mobile network at all. Some did report success after many reboots.
