Emergency calls are not possible when the radio is off. In fact, navigator.mozMobileConnection.voice.emergencyCallsOnly should be false in this case. If it's not, we should file a Gecko bug, but for now I suspect this is a Gaia issue.

By radio, do you mean not having a sim card installed?  #1711 ... it wouldn't be able to make a call would it...

No. I'm talking about the `ril.radio.disabled` setting. The radio can still be active when not having a SIM card installed, and it's still possible (in some locations at least) to make emergency calls.

Oh!  Didn't realize that was possible.  Thanks for the info.

Yup. But that's really besides the point. The point is, when the radio is off, signal strength, emergency calls, SIM card status: they're all not available and none of those things should be shown the user.

Blocking, as this presents a danger if the user thinks they have the ability to make calls.

WFM

STR:

- Go to Settings app
- switch on Airplane mode
- press the sleep key to turn off the screen
- turn on the screen again
- observe the lock screen

Expected:

- Lock screen showing "Airplane mode"

I'm not sure if that's really good STR for this - I'm concerned about the case where no network is available even if we'd be looking for one. We also shouldn't make the user believe (s)he can make emergency calls in that case, IMHO.
