For all countries, you can just dial 112. Dialling 112 will direct you to the same emergency call centre as phoning the country's emergency number would. In the EU, emergency call centres must provide a translations service. In some countries a phone does not even need to have a SIM card present to dial 112.
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 India and 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 or 000 in Australia).
Note that data only sims might not be able to dial emergency number in some countries.
