Jambo Telkom, a subsidiary of Telkom has started offering internet connections as an internet service provider (ISP) and competing against other ISP’s like wananchi and Africa online.
Simple: All you need is a Telkom telephone line and a computer with a modem installed. Dial 9444 with your modem then enter the username jambo and password jambo and your are connected directly to the internet (at 56kps max). Charges are the normal local call rates.
Jambo was originally licensced in 2002 and at the time regulators assured other ISP's that Jambo would not be subsidized by Telkom to drive them out of business.
