Warms the cockles of your heart. Yes. A 62 year old chap was recently caught-up-a-freezing mountain with only his handset and a mobile signal to help.
Cue the London Telegraph:
Martin Stone, 62, got lost after climbing a 3,615 ft peak alone during a holiday on the island of Majorca.
He sent an SOS text message to his wife back home in the Midlands, who called British emergency services.
Spanish rescue workers launched a massive search operation but Mr Stone was spotted the following morning only thanks to his bright red scarf.
I bet that 50p international text was worth it.
