People are increasingly moving across EU countries for job or holiday reasons. Therefore, it is extremely important to have a number to be used throughout Europe and dialed in case of emergency. The number is 112 (one-one-two), the Single European emergency Number.
The call from a fixed or mobile telephone or App is free of charge. Those who receive the request for help have immediately at disposal the telephone number of the person who is calling and can see his/her position on a geographical map.
You can explain what you need, even though your language is different from that of the country where you are, thanks to a multi-language service allowing for the simultaneous translation of the call with the support of a translator.
