Connectivity
Wits relies on Eduroam to manage access to the WiFi network. Please ensure that you have your university's Eduroam credentials setup on your devices before you leave your home campus. Eduroam is now accessible in South African airports, which is another good reason to set up your credentials. There is also 30 minutes of free wifi available from AlwaysOn at the airport.
If you don't have decent roaming it's probably a good idea to pick up a SIM card and some data when you arrive. You can do that from the Vodacom shop in the Arrivals Hall. It will cost you about R115 and include some airtime. You can also buy Sim cards from most Checkers or PnP stores, but you'll need to show your passport details. Data can be purchased from the same stores.
Accommodation
Johannesburg has an enormous range of options for accommodation. The hotels in Rosebank -- the Monarch, Holiday Inn, Hyatt and the Crowne Plaza -- are all convenient to the shops and the Gautrain, but they are also expensive. There are many B&Bs in Melville; the Lucky Bean, the Melville Turret, the Wedgwood are all good value, very comfortable and they include breakfast.
Transport
Unless you are arriving after 8:30pm, we recommend that you use the Gautrain to travel between the airport and the city. It is very quick, clean, efficient and possibly the safest space in the country. You will need to buy a card, which you can do in the Gautrain station, and load it with at least R340 (the cost of a return ticket). The journey between the Airport and Rosebank normally takes about 30 minutes.
The Gautrain station is on the top floor on your right hand side of the airport Arrivals building. You will need to travel up two long escalators. It is signposted.
The train travels via two other stops to Sandton and it comes to a standstill where you must get out. At Sandton take the escalators up one flight and take the train to Park Station, usually from Platform B. If in doubt ask one of the many security officers or another traveller. On a weekday these trains run frequently. On weekends and public holidays they run only every 30 minutes so if you're unlucky you can easily wait for a twenty minutes.
Uber works well in Johannesburg although it will require you to have access to data. Most Uber drivers prefer to pick people up from the Airport Departures Drop and Go of Terminal B which is the top floor of that building. (Arrivals are on the ground.) The fare will be between R250 and R300.
There are touts in the OR Tambo Airport arrivals area; they're not aggressive but you should not engage with them ...
Things to do. If you're arriving early or late you may be wondering about things to do. Johannesburg is a very interesting city, with much to do and to learn. There's a good list at https://www.inyourpocket.com/j
