Please test and expand on the script below.
I don’t speak python well so I’m sure it can be improved. Also I could not actually test it, as I’m not currently within range of one of those countries.
What it does:
- listen on ofono interface for operator changes
- compare “current” (i.e. used) network ID with blacklist
- if net is blacklisted, disable roaming (actually, it just prints something, if you want to really disable roaming, uncomment the
connman.SetProperty part).
It’s not ideal, because what we really want is to select an non-blacklisted operator instead of disabling Roaming, but I guess that’s within ofono…
This can be run from a systemd service, for now, just run from command line.
