112 (emergency telephone number)
112 is a common emergency telephone number that can be dialed free of charge from most mobile telephones, and in some countries, fixed telephones in order to reach emergency services (ambulance, fire and rescue, police).
112 is a part of the GSM standard and all GSM-compatible telephone handsets are able to dial 112 even when locked or, in some countries, with no SIM card present. It is also the common emergency number in nearly all member states of the European Union as well as several other countries of Europe and the world. 112 is often available alongside other numbers traditionally used in the given country to access emergency services. In some countries, calls to 112 are not connected directly but forwarded by the GSM network to local emergency numbers (e.g. 911 in North America, 999 in the United Kingdom and Hong Kong, and 000 in Australia).
