Johannesburg is a sprawling city and the lack of convenient and safe public transport is often an obstacle to visitors. City transport consists of an unreliable bus network and a series of minibus taxi routes, neither of which operate much after dark. The main bus terminus is at Gandhi Square in the city centre, where there are timetables and route maps, but times are rarely accurate. The Gautrain train and bus service is safe and reliable but only stops around Sandton and surrounding suburbs, though it is very useful for getting to and from the airport. The quickest and cheapest way to get around is on a minibus 'taxi', an informal bus service that goes everywhere but has no schedule or formal stops and can be hailed anywhere along its route. However, dangerous driving and overcrowding deter many from using them as a means of transport. If necessary, use them for short hops only and never with baggage. Metered taxis are safer but far more expensive. The best way to get around is by private car and there is an excellent network of highways and well-maintained roads. Drivers should keep their windows up and doors locked at all times, never leave anything visible in a parked car, and never stop for hitchhikers.
Electrical current is 230 volts, 50Hz. Round, three-pin plugs and round, two-pin plugs are standard.
South Africa's currency is the Rand (ZAR), which is divided into 100 cents. Money can be exchanged at banks, bureaux de change, and the larger hotels. ATMs are widely available and major international credit cards are widely accepted. Visitors should be vigilant when drawing cash from ATMs, as con artists are known to operate there. All commercial banks will exchange foreign currency.
The international access code for South Africa is +27. Mobile phone networks are available across the country, and there are roaming agreements with most international mobile operators. Mobile service providers offer very cheap 'pay-as-you-go' SIM cards, which are a good option for visitors staying for some time. Internet cafes are available. Wifi is easily available, especially in the larger cities.
Emergencies: 10111 (Police), 10177 (Ambulance), 112 (cellphone emergency number).
