It seems that 112 is routed to the police. When calling the emergency numbers, the phone carrier transmits the radio cell location.
What I didn't know is that the ability to call 112 from a cell phone without SIM card was deactivated briefly after it was introduced first in 2000. I wonder if it works now? (No invitation to try it of course)
