Network Coverage And Performance

Telkom SA SOC Limited achieves a Coverage Experience score of 5.4 out of 10 and ranks third among South African operators for geographic coverage reach. The operator's users spend 99.1% of their time with an active 3G, 4G, or 5G connection — the highest availability score in South Africa — according to the OpenSignal South Africa Mobile Network Experience Report published August 2025.

Telkom's 4G LTE network spans all 9 provinces of South Africa, with the strongest population density coverage in Gauteng (including Johannesburg and Pretoria), KwaZulu-Natal (Durban), and the Western Cape (Cape Town). Rural reach remains more limited compared to Vodacom and MTN, whose coverage experience scores of 8.0 and 7.4 respectively indicate wider geographic distribution in low-density areas.

4G And 5G Availability

Telkom operates an LTE 4G network nationwide and a 5G network currently deployed across 4 provinces: Gauteng, KwaZulu-Natal, Eastern Cape, and Western Cape. The operator launched 5G using 125 base stations with an initial focus on fixed wireless access (FWA), with mobile 5G planned as subscriber demand increases, according to Connecting Africa published September 2024.

Telkom's LTE network operates on spectrum bands including 700 MHz (Band 28) for wide-area coverage and 1800 MHz (Band 3) for urban capacity. The 5G deployment uses the 3.5 GHz mid-band spectrum, which balances urban speed with reasonable reach. Approximately 14% of Telkom's device base is 5G-enabled as of mid-2025, according to OpenSignal data published August 2025 — indicating early but growing 5G adoption among subscribers.

The 5G rollout prioritises high-density urban areas including Soweto and Mamelodi in Gauteng, Umlazi in KwaZulu-Natal, and key corridors in Cape Town and Port Elizabeth, with Telkom committing to expand into smaller towns progressively.

Speed Test Results

Telkom delivers an average download speed experience of 18.3 Mbps and an upload speed experience of 4.8 Mbps nationwide, ranking fourth in download speed among South Africa's five operators, according to the OpenSignal South Africa Mobile Network Experience Report published August 2025.
