This is a good lesson to learn the local phone numbers for emergencies...
911 in the US
999 in the UK
and, I just looked it up
112 in Spain...
If your cell phone is non-local, how to dial these numbers is also a good thing to know.
Beats texting mummy thousands of miles away...
Tip: Telephones in AU and NZ dial backwards: 000
in AU, 111
in NZ.
If all else fails, 112
should work in 81 countries. (In countries where it is NOT the native emergency number, it only works on cel phones, and rings only the police.)
