Dear All
FYI
If you travel to work on the tube please note the following information:
If your mobile phone has no signal (if you are in a tunnel) you can dial 112 and it will divert to a satellite signal and this 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 do not know where you are.
Please forward to people you know.
