Live Poll

Do you think your mobile network's service is getting better or worse?

MTN won or shared 10 of 16 awards in Opensignal's November 2026 report on South African mobile networks, which measured user devices between 1 July and 28 September 2026. Vodacom swept the 5G download speed and 5G coverage awards.

Why it matters

The rankings show MTN's lead across consistent quality, download and upload speeds and 5G availability, while Vodacom leads on 5G performance and Rain's network is connected to 5G for a large share of the time. Readers choosing a provider in South Africa can weigh these differences in speed, reliability and 5G access.

Opensignal's measurements from users' devices show MTN's 56.4Mbit/s average download speed and 71.9% consistent quality score, compared with Cell C's 66.9%. Vodacom's 5G download average of 231.1Mbit/s and Rain's 49.4% share of time on 5G set the upper range of the report.

Roadmap

MTN won 11 of 15 awards in Opensignal's August 2025 report, including all four overall experience awards, and this November 2026 report keeps it at the top with 10 of 16. The shift is that Vodacom now leads on 5G speed and coverage while MTN's network capital spending was cut by 17.1% in the six months to June 2026.

If you are choosing a mobile provider in South Africa, MTN's consistent quality and upload and download scores suggest steadier everyday performance, while Vodacom's 5G results matter if you use 5G devices. Rain's lower reliability and consistent quality scores are worth weighing before switching.

The takeaway

No single operator led every category, so the best choice depends on whether you prioritise consistent speed, reliability or 5G performance. Check the category results before deciding which provider fits your needs.
