Telkom SA SOC Limited

Telkom SA SOC Limited, also known simply as Telkom, is a South African telecommunications company headquartered in South Africa. It provides a range of services including fixed-line voice, mobile telecommunications, broadband internet, and data solutions to customers across the country. The company's offerings encompass consumer, business, and wholesale markets, delivering voice calls, SMS, USSD-based services, mobile applications, voicemail, and call centre support. These services are delivered through its network infrastructure that supports both legacy copper lines and modern fiber‑optic and wireless technologies. The 2017 WannaCry incident highlighted the breadth of its customer‑facing platforms, showing that its USSD menus, mobile apps, voicemail systems, and call centre operations are integral to its service delivery.

As a state‑owned enterprise indicated by the "SOC Limited" suffix, Telkom operates under government ownership and is subject to South African telecommunications regulation. Its position as the historic incumbent fixed‑line operator gives it a distinctive role in the nation's communications sector, particularly in providing universal service obligations and maintaining critical infrastructure. The company’s competencies include managing large‑scale network operations, securing customer data against cyber threats, and maintaining service continuity despite incidents such as the WannaCry attack. Following the 2017 WannaCry incident, Telkom implemented traffic throttling and enhanced monitoring to safeguard its networks and customer data. While specific figures on subscriber count or revenue are not provided in the source material, the organisation’s headquarters in South Africa and its extensive service portfolio underscore its significance as a key telecommunications provider in the region.
