One number that works in 27 EU countries – without credit.
112 reaches ambulance and fire services across the EU, free of charge, even on a locked phone or without SIM credit. The dispatcher asks: Where did it happen? What happened? How many people affected? What injuries? And: wait for follow-up questions – don't hang up. Since 2009 it's marked by a European Day on 11 February.
Useful: Say “where” first – if the call drops, the dispatcher still knows where to send help.
