Description
In the wake of bombings in London in July 2005, a chain letter
began to be distributed across the internet claiming commuters
could reach the emergency services even when underground by
calling 112. The chain letter claimed that this would connect mobile
phones to a satellite, even if the phone had no signal.
Whilst it is true that calling 112 will connect to the emergency
services just like 999 (the number traditionally used in the
United Kingdom), it is not true that the number can be used
when there is no mobile phone signal.
Furthermore, even expensive satellite mobile phones require
a clear "line-of-sight" with the satellite in order to operate, and
so will not work on the London Underground system.
Sophos recommends people do not foward the chain letter onto
fellow computer users, as it provides no useful function.
The text of the chain letter reads as follows:
Important Number you should note
If you travel to work on the tube please note the following
information: If your mobile phone has no signal (so even
if you were in a tunnel) if you dial 112 it diverts to a
satellite signal and puts you through to the 999 call centre.
ALL phone companies have signed up and as it is a satellite
service it also gives them a trace to you if you don't know
where you are.
Another version of the chain letter reads as follows:
This is worth knowing if you get the tube. It goes straight to
emergency services.
From someone who was on a First Aid course....
We were told about a very under publicised but very useful emergency
number.
If your mobile phone has no signal (so even if you were in a tunnel) if
you dial 112 it diverts to a satellite signal and puts you through to
The 999 call centre.
ALL phone companies have signed up and as it is a satellite service it
also gives them a trace to you if you don't know where you are.
I thought this was worth sharing please pass it on.............................
