Good stuff. Another piece of advice that used to be offered to Army Cadets and Scouts was to enter a contact on your phone under 'ICE' (in case of emergency) with your chosen contact number, that way if you got lost and had an accident the emergency services would have a number for somebody they could contact.
Really confusing though! Just registered for texts as explained by sending "register" to 112. You get back a message telling you to send "Yes" to 999 - and it then explains that in an emergency you should text 999! In the video he says text 112 in an emergency!
Actually I think either would work - but joined up thinking? I don't think so!
