Hiring a car is very expensive in Singapore. However, an extensive bus network and the reliable MRT train subway system are both cheap and user-friendly and service all parts of Singapore. Electronic EZ-Link passes cover trains and buses and prevent the need to carry loose change for fares as well as giving a slight discount on standard ticket prices. The city also has thousands of metered taxis, which are safe, air-conditioned and surprisingly affordable, driven by helpful and honest drivers. The only drawback is the long taxi queues during rush hour. Many of the tourist attractions are situated close together and walking is a safe and pleasant option if you can handle the heat.
Electrical current is 230 volts, 50Hz. Three-pin, square-shaped plugs are in use.
Singapore's currency is the Singapore Dollar (SGD), which is divided into 100 cents. The US and Australian Dollars, Yen, and British Pound are also accepted in the larger shopping centres. Major credit cards are accepted in hotels, shops, and restaurants. ATMs are widely distributed and banks advance cash against the major credit cards. Banks are open daily, but some do not do foreign exchange on Saturdays.
The international access code for Singapore is +65. The outgoing code is either 001, 002, 008 or 018, depending on the service provider, followed by the relevant country code (e.g. 00144 for the United Kingdom). Calls made from hotels are free of any surcharges. There are several local mobile phone networks available, internet cafes are common throughout Singapore, and wifi is easily available.
Emergencies: 999 (Police); 995 (Ambulance and Fire).
