Build your emergency contact card before departure, because the moment you need it is exactly when research is impossible.
A detail worth knowing: 112 works from mobile phones in much of the world even where it is not the advertised number, and smartphones' built-in SOS features dial local emergency services correctly and can share your location, so learn how yours activates before you travel.
Store the list three ways: in your phone contacts, on paper in your wallet, and with someone at home who holds your itinerary. Add your accommodation addresses written in the local script, which turns any taxi into a rescue when your phone dies. Ten minutes of preparation converts most travel emergencies from crises into inconveniences.
