How does Emergency Calls work? |

The title sounds daft, but still. let me lay out the origin of my question. This afternoon I drove home after working in Milton Keynes and did not feel going through the roadworks on the M25 so I had my GPRS contaption map the shortest route avoiding Motorways.
Anyway, I was driving in the middle of nowhere in the countryside in a hilly area when I lost my mobile signal with 02. On the phone the operator logo was replaced with "Emergency Calls Only".
Now, how can I make an emengency call when I have no signal to my normal provider? Or, do you then make use of any available operator's signal (Vodafone, Orange etc.)?
Any comments?

okay so where does the call go to ? To the local police station or something or to some international emergency center or somewhere else ?
If at first you don't succeed, destroy all evidence of your attempt !! |

SIM means subscriber identity module and it simply identifies you to the phone company (via the SIM cards serial number combined with the phone IMEI I believe)
it doesn't actually make the phone work, as such

but how??
if i dont have a sim in my phone i can still call 999/911/112
but how the hell on earth that can happen? where does the call go and how? surely my call has to get connected to a network? and that isnt going to happen without my having a sim card in the phone!
only way it would work is if the emergency services has an network?

i have an old t61d (no sim card even) and i can still make emergency calls with it, and its pretty old. as long as its charged, it will work
this had me thinking... the normal for emergency is 911 (in the USA anyway, idk about other countries) so why do 08 and 112 make emergency calls??
and the t630 can make emergency calls while the keys are locked btw
edit: @fatreg, your sim identifies who you are... you know how phones can be unlocked right? then it can work on any network (network that ur sim is on) well when u make an emergency call, its like its automatically unlocked for those numbers, so it will work on all networks. thats the best way i know how to explain it.
when u dial 911 from a payphone, or house phone where does it go? to the local police station, thats where it does when u make an emergency call.

All /// Ericsson & NOW the SE onez undo the keylock if you press. 112 and call/ yes button. THAT is the orignal Intl emerg code. As said by all here- at some locations operators (unlike here in India) let the signal connect to some desk of therez, irrespective of who's service you on. #
Goes w/o saying, it wont work under 'No Network' situation. That is, some (anybody's) signal has to be there AND that carrier should be considerate enough.

thats what i have ALWAYS thought about... im suprised noone has tried to edit the software, and add phone numbers instrad of the emergency numbers, and make free calls... i wonder about that. i knwo it is illigal, but still.

*lol*  dude THAT wont happen unless yor gurlfrnd works in the callcntr & helps u out. As for your HOW- i think the capability to detect the signal & freq. , initiation & such techni'lities STILL ARE with the handset, rite? So its possible w/o SIM.
