It looks that NetworkManager is involved in this. As I recently discovered, ConnectionManager's property persists across ofono re-starts and also when we offline/online modems. So this should not really be a system-settings issue. With the configuration said in the bug description (SIM 2 data activated), I have sneaked at the DBus interface while **setting** flight mode. I have seen:

If instead of having SIM 2 powered I have SIM 1, I do not see this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1376957 Title: Cellular Data Prefs not preserved if FlightMode enabled, then disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-system-settings/+bug/1376957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
