Reboot needed after changing SIM state
I have a SIM card inserted in my devkit and I see the proper icon indicating that I have cellular signal:
Then I remove my SIM card, but the icon never changes. If I reboot the system (leaving the SIM out), then when it boots back up, I see the correct SIM icon:
The same goes for if I start with no SIM and then insert one. A reboot is always needed for this icon to change. Instead, I would expect that the state change is updated when the hardware change is detected.
