Bug Description

This bug is being reported after being reproduced on krillin running rtm image #72 + a pending version of urfkill and indicator-network from silo-024 ( urfkill: urfkill 0.6.0~20140708.110711.a0581f3-0ubuntu2 ).

With two unlocked SIMs installed, and SIM#2 selected for mobile-data ( 2G is the only option ), when flight-mode is enabled, the cell settings page no longer displays the two SIMs under 'Cellular data:' , it just displays 'Off', '2G only...', '2G/3G/4G'. This is likely due to the fact that the ofono SimManager interfaces disappear when flight-mode is enabled on krillin ( hardware quirk ).

When flight-mode is disabled, the UI is restored, however 'Cellular data' is set to Off.

@awe, could you take a look at bug 1375832 and see if you've duplicated it? Just seems this would happen no matter past flight modes.

I definitely see differences between single SIM and dual-SIM. Bug #1375832 involves a single SIM in slot2, and I can't get mobile data to enable at all.

This bug deals with dual SIMs installed, and it appears I can enable mobile data on one of them, it's just when FM is enabled, it causes system settings to forget that mobile data is enabled, and which SIM was selected.

Both might be caused by the same underlying bugs, but based on symptoms alone, they're not the same.

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:

...
method call sender=:1.8 -> dest=org.ofono serial=3356 path=/ril_1; interface=org.ofono.ConnectionManager; member=SetProperty
   string "Powered"
   variant boolean false
...

root@ubuntu-phablet:/home/phablet# dbus-send --system --print-reply --dest=org.freedesktop.DBus / org.freedesktop.DBus.GetConnectionUnixProcessID string:":1.8"
method return sender=org.freedesktop.DBus -> dest=:1.125 reply_serial=2
   uint32 1395
root@ubuntu-phablet:/home/phablet# ps -ef|grep 1395
root 1395 1 0 20:23 ? 00:00:02 NetworkManager

NetworkManager is powering off ConnectionManager SIM 2 interface. If instead of having SIM 2 powered I have SIM 1, I do not see this.

@Alfonso

I changed the NM task to Incomplete, as I'm not sure NM is still involved. The original NM/ofono patches actually would toggle the ConnectionManager's 'Powered' attribute, however this code was removed, so I think this can be considered 'FixReleased'.
