Coming to SA on Monday - buying a SIM card?

[Shellz_Mach1]

Arrive in Johannesburg Monday morning (guess the airport is no longer called Jan Smuts!) and will need to get myself a phone or at least a SIM card as soon as I get there. In the UK there's a shop on every corner just about, is it as easy in SA? Is it remotely possible that I will be able to buy a pay as you go SIM at the airport?

Any advice hugely appreciated.

Thanks

Thanks for that Amabok. I landed yesterday and rented really easily a dongle modem for just over a quid a day with SIM card good for calls too. Charges are high, I reckon I've clocked up about a fiver already in about 36 hours!
