In both cases, the smartphone is one of the most important companions on holiday as a sat nav, communications hub, photo and video camera, local tour guide and games console, because it can also become a troubleshooter in difficult moments. In addition to accessing social media to stay in touch with friends and relatives, the most important aspect of the smartphone is the ability to make an emergency call. Most reliable companion in the open: the European emergency number 112 In Austria, all three-digit emergency numbers, including those of the two major automobile clubs, are free of charge. The European emergency number 112 should also be saved for a holiday in Austria. This number can be used to make an emergency call even if the home network - for example in uninhabited alpine areas - is not available, but at least some network is within range. In addition, calls to the European emergency number 112 are prioritised by the mobile networks, which means that a 112 emergency call is given priority over all other connections. The European emergency number 112 can also be dialled without a contract or credit. For holidays abroad: always dial 112 in an emergency The various emergency numbers differ abroad. This is why the European emergency number 112 is considered an international emergency number. If 112 is dialled anywhere in Europe (always without an area code), the system automatically connects to the nearest emergency call centre. In Austria, these are the police control centres. Saving international area codes Saved phone numbers only work abroad in the international format: for example, 06(…..) becomes +436(…..). It is therefore advisable to check at least the most important contacts and correct them if necessary. EU roaming "Roam like at home" - data usage like at home in other EU countries
