Default 999/112 Urban myth?

Please would someone who is in the mobile industry at a technical
level confirm which of the following is correct.

To start with, I have always understood that:
a) 999 & 112 are functionally identical
b) your phone will use any available network, irrespective of SIM or
network locking

However I was recently told that 999 only uses your network, but 112
uses any.

I don't see how the latter can be true, as there are a lot of
"vulnerable people" schemes that use old SIM-less phones for emergency
calls and they advertise use of 999.

Have I been told an urban myth? Which is correct?


Thanks!



Jim

Yes.

Your phone will try to, but can only make emergency calls on its own
network.

What happens with a SIM-less, unlocked phone?

Are you saying if it is locked, it will only use the locked network?

You'd be unable to make emergency calls.

No, a network will only let a phone make calls including emergency calls
if it has a SIM for that network. It's nothing to do with a phone being
locked.

OK, related question then.

How do these "vulnerable people" schemes work then? Do they have
special SIM's?

I'd think they just carry a mobile with a PAYG sim in it?

No SIM, no call.

Any phone can only make a call, emergency or otherwise, if it has a valid,
working SIM. End of story.

If you want to a phone that will roam to any available network in an
emergency, then you will need to get a foreign SIM. I believe there are
some very nice one from Liechtenstein.

A lot of phones will allow you to make 999 calls without any SIM
installed.

DOn't know about a, but b is bollocks.

In the UK a mobile phone can only use the network of the SIM card
inserted in it. There are no national roaming agreements that permit
network A traffic to run over network B.

(I'm ignoring the 3/orange/02 situation as this is not roaming as far as
the end user is concerned)

Are there? None of them will work then.

> Have I been told an urban myth? Which is correct?


To dial 999 from a mobile you need a functional SIM card and you need to
be in range of the network.

You can't call out from it. Not even to 999.

A locked phone will only be able to accept a SIM from the network it's
locked too. If you can get past that then you can make calls.

No, they would have to have ordinary SIMs.

Because some countries allow emergency calls without a SIM. The UK
networks do not.

Try to place the call and see what happens.

Indeed. However in the UK the call will not connect.

Try it. And when you have done, post back here.

IIRC, the GSM standards refer to 112 as the one and only internationally
binding emergency number. However, 999 or 911 (for the US) might work as
well. I understand that in the UK emergency calls would not be routed
without a valid SIM in the phone, in Germany for example they definitly
would. IIRC it is only the 112 but this one definitly, irrespectively of
any SIM, phone lock or whatsoever (provided the phone is technically ok
and just any network provides coverage). Even works on phones with key
lock on without releasing the key lock.

Cheers,
Horst

As I understand it when you dial 999/112/911? the phone interprets this as an
emergency call and actually sends a GSM emergency call code to the network,
hence dialing 911 or 999 in North America would work, is this true or another
myth?

I think where this stems from is, that originally there was a European wide
plan for mobile phone to be able to connect to an emergency number and
bypassing the normal conditions of having the correc sim/ a sim or credit on
your sim. This was implemented in a number of European countries but the UK
networks decided that they didn't want to offer this service.

This may have been down to the fact that a higher percentage of phones are
subsidised and therefore network locked in the UK than the other countries.

I was discussing this very question with a friend the other day, and we had
both always assumed that a phone WITH a SIM, but not in range of its own
network, would be able to roam for the purposes of making an emergency call.
It is after all part of the GSM spec.

I was in a position to try it recently, and as Jon says could not place the
call - the UK networks have clearly not implemented this. I wonder how many
people have died as a result of this policy / assumption?

Benedict.

I wonder how many people have died for not carrying a mobile phone at
all. How did the last generation survive in an emergency without
mobiles? Or before that without phones!

Because the GSM specification requires phones to try to make such
calls. However, in the UK (and some other countries) nothing happens
as the networks have chosen not to accept these calls.

More would have died, in the past people used to die of all sorts of things
that are now curable by medicines.

IMO the previous posters question stands.

The risk obviously isn't large enough for Ofcom to intervene -- and
that's probably because there is so little difference in the coverage
of the mobile networks.

Most likely. Would only really be a benefit in countries where there are
several regional operators, rather than a handful of operators with national
coverage.

I think that apart from 112, which is always treated as an emergency
call, it depends on the phone and whether it recognises the number
dialled as an emergency number. Some phones allow the list of such
numbers to be configured in the UI, but my current one (9300) seems
not to.

I suspect there are large areas of the highlands where that are not covered by
all 4 networks.

From personal experience, I know this to be true - although it has
improved somewhat over the past few years.
