Specialists Leave Mobile Operators Behind on Home Internet

Why It Matters

The rankings prove specialist ISPs can deliver superior home connectivity, pressuring mobile operators to upgrade their fixed‑broadband offerings and reshaping South Africa’s broadband competitive landscape.

Key Takeaways

• Vox topped download, upload, video, reliability in Opensignal Q1 2026.
• Vox’s upload speed 17.5 Mbps, 6.4 Mbps ahead of Vodacom.
• Reliability score: Vox 363 vs Vodacom 246, an 80‑point gap.
• Fixed broadband subscriptions rose 19.3% YoY to 3.26 million in 2025.
• Rain’s fixed‑wireless grew 39% to 1.26 million, ranking second overall.

Pulse Analysis

Opensignal’s crowd‑sourced benchmark blends fibre‑to‑the‑home, 5G fixed‑wireless and legacy wireless into a single "fixed broadband" ranking, offering a real‑world view of household connectivity. Vox’s sweep of all five metrics—download, upload, consistent quality, video experience and reliability—signals that a specialist ISP can match or exceed the performance of entrenched mobile operators. The modest 24.9 Mbps download figure reflects the test’s focus on lower‑tier packages, but the 17.5 Mbps upload and 363 reliability score underscore a clear advantage for users with multi‑device, cloud‑heavy workloads.

Vox’s edge stems from structural factors unique in the South African market. As a sister company to Frogfoot under the Vivica Group, Vox controls both the network layer and the ISP layer, eliminating the resale inefficiencies that plague many rivals. Its recent Google peering accreditation further boosts video performance, a key driver of the high video‑experience score. In contrast, mobile operators such as Vodacom and MTN rely on retail broadband bundles that, despite extensive fibre footprints, lag in real‑world reliability and upload capacity, exposing a gap between network investment and end‑user experience.

The broader industry context amplifies the significance of these findings. Fixed broadband subscriptions jumped 19.3% year‑on‑year to 3.26 million in 2025, while fixed‑wireless access surged 39% to 1.26 million, indicating rapid consumer migration away from mobile‑centric home internet. As household penetration remains low at 17.4%, growth potential is substantial. Mobile operators will likely need to deepen fibre partnerships, improve wholesale terms, or develop their own specialist brands to stay competitive. Meanwhile, specialist ISPs such as Vox are poised to capture a larger share of the expanding market, leveraging network ownership and strategic peering to deliver the reliability and speed that modern households demand.
