MyBroadband Insights has published its Q3 2020 Mobile Network Quality Report, highlighting the best and worst mobile networks in South Africa right now.
The report is based on 334,257 speedtests conducted by MyBroadband Speed Test App users across the country between 1 July and 30 September 2020.
The research shows an average mobile download speed of 29.16Mbps and an average upload speed of 11.46Mbps across all networks.
MTN had the highest average download speed at 55.11Mbps, followed by Vodacom on 29.80Mbps, Telkom on 23.60Mbps, Cell C on 17.82Mbps and Rain on 10.02Mbps.
“Over the last quarter the average network speed of South Africa’s mobile operators increased despite the increased network traffic,” MyBroadband said.
“This was made possible by temporary spectrum which was issued to mobile operators during the lockdown.”
MyBroadband said this temporary spectrum helped mobile networks to increase their network capacity and improve their average speeds during the lockdown.
There was one exception – Rain. The average download speed on Rain’s network declined significantly during the lockdown because of congestion problems.
Before the lockdown, Rain’s average download speed was 15.20Mbps. After the lockdown started the average speed plummeted by 30%, to 10.02Mbps, which shows the impact of increased traffic on network performance.
Best mobile network in South Africa
To determine the best mobile network in South Africa, a “Network Quality Score” was calculated for each network using download speed, upload speed, and latency.
The Network Quality Score out of 10 then shows how the network performed in relation to other networks.
MTN reigned supreme with a Network Quality Score of 9.68, followed by Vodacom on 5.99, Telkom on 5.16, Cell C on 4.27, and Rain on 3.74.
