Default 112 vs 999

I was recently told by someone connected with the emergency services
that you should always dial 112 from a mobile rather than 999. The
reason given was that with 112 the operator will know your location
within a matter of metres whereas with 999 they only have a rough idea
where you are calling from.

My gut feeling on hearing this was that it's nonsense.

I, from personal experience about 10 years ago, know they have a rough
idea where you are from which mast you are using. Bitter experience
actually as I was near a county boundary and the operator would no way
connect me to the correct force, insisting on the neighbouring one,
who then had to ring up the correct one and relay a message!

I've done much Googling on this subject but can't find any up to date
info on this.
"enhanced location information" seems to have been introduced about
2004 giving more accurate location info, based on triangulation I
think. But why would this work on 112 and not on 999.

Anyone know for a fact whether what I've been told is truth or
garbage?

As far as I can tell, 112 and 999 are effectively the same. Whereas the
emergency operator has a frequently updated database matching land-line
numbers to their physical addresses, that's obviously pointless for mobile
numbers.

While it is possible to identify the 'cell' used to make a mobile call,
that is not very accurate (a radius of several yards in the middle of a
city, but possibly a few miles out in the sticks). I can't see how it
makes a difference whether you dial 999 or 112. A mobile caller should
tell the operator as accurately as possible where the emergency is.

Some 'smartphones' are now capable of identifying their own location to a
certain extent, the best probably using an integrated GPS receiver and
mapping application. I don't know if the emergency operator has any way
of tapping into that information as yet, but I wouldn't be surprised if
the emergency services are investigating the possibilites. ("Geolocation"
seems to be the buzzword associated with that sort of thing).

Garbage. The reason for 112's existence is so that all EU member states
have a universal emergency number. It makes no sense at all to have two
emergency numbers work in different ways.

There was a story about someone in America that accidentally called 911
from a mobile phone that he had stolen. He was selling drugs and the
operator could hear the conversation and was able to give the police the
caller's exact location.

It didn't say how this was done but I imagine it must be through GPS. I
can't imagine mobile manufacturers didn't consider the possibility of
allowing GPS coordinates to be sent when an emergency call is made.
Unless there were privacy concerns I can't think why this wouldn't have
been implemented.

One difference is that many phones will allow you to dial 112 with the
keypad locked, while other emergency numbers require the keypad to be
unlocked.

(I have no idea if there is country-specific firmware to also allow national
numbers)

Default 112 vs 999

On a recent re-run of this topic a comment was made that many modern UK mobiles will actually dial 112 even when you input 999.

This is to make sure that you get the Emergency Operator wherever you are in Europe. It would be no good dialling 999 at the scene of a road accident in France and get through to a UK operator, whereas 112 will always get you to the local lot - whether or not they speak English is another matter altogether!

112 and 999 are also (allegedly) the only numbers that can be dialled without a SIM card in the phone.

There are also (allegedly) moves afoot to enact cross-service coupling such that if you dial 112/999 when out of range of your own SP the phone will roam onto any network it can find to complete the call.

No longer allegedly. Been that way since the last quarter of last year (or
thereabouts).

More likely an urban area with small 'cells' and the cops knew how to spot
a dealer in action, or knew him by sight already, or possibly locked on to
the signal from his handset. In analogue days they could probably listen
to the actual conversation using a simple 'scanner' (as could journalists
hounding careless 'celebs').

"Geolocation" currently requires deliberate activation of the equipment
and software, and an internet connection to a suitable web site to
'publish' the information. Of course if a thief unwittingly steals a
handset that is already so connected ...

When I had one of Nokia early phones (had the original 'snake' game) if
the keypad was locked and I dialled 999 or 112 it would give me the
option to call it, like on all phones.

When I went on Spain on holiday I tried it again and it would only do it
for 112, not 999. Somehow the phone 'knew' what the emergency numbers
were for the country I was in.

It seems this feature doesn't exist in new Nokia phones though.
