Key Findings
Vodacom surpasses the 200Mbps mark for 5G Download Speed
In the previous report, MTN and Vodacom jointly won 5G Download Speed. However, our Vodacom users saw a stunning increase of average 5G download speeds of 66.6 Mbps — 45.8% faster compared to the last time. Vodacom pulls ahead of MTN which saw no statistically significant change in its score compared to our llast report. As a result, Vodacom breaks out of the statistical tie it was in with MTN and wins 5G Download Speed outright with a score of 212.2Mbps, commanding an impressive lead of nearly 30% over its competitor. MTN retains 5G Upload Speed, although Vodacom halves the gap between the operators for this metric from 6.6 to 3.3 Mbps.
MTN wins 5G Games Experience outright, but Vodacom keeps overall Games Experience in a firm grip
After sharing the podium for 5G Games Experience with Vodacom in the last report, MTN wins the award outright with a score of 39.5 points. Vodacom comes second, 1.2 points behind the winner. However, Vodacom retains the overall Games Experience award with a score of 34.1, 0.8-1 point ahead of Cell C, MTN, and Telkom that statistically tied for second place, with scores in the 33.1-33 points range.
Vodacom comes first for 5G Video Experience
Vodacom wins 5G Video Experience outright with a score of 77.8 points — beating MTN by 1.9 points. Both operators rate as Very Good (68-78), which means our users are, on average, able to stream video at 1080p or better with satisfactory loading times and little stalling. However, MTN jumps on the winners’ podium for the overall Video Experience and shares the award with the previous sole winner Vodacom, with scores of 47.2-49 points.
MTN retains its awards for the fastest overall speeds in South Africa
MTN users see the fastest average overall download and upload speeds in South Africa. The operator wins Download Speed Experience outright with speeds clocking in at 29Mbps — 3.9Mbps (15.4%) faster than Vodacom’s result of 25.1Mbps. Cell C and Telkom lag behind, with scores of 13.1 and 11.8Mbps, respectively. MTN also keeps Upload Speed Experience in a firm grip, with a score of 6.4Mbps, commanding a lead of 0.9Mbps over Vodacom.
Telkom remains the sole winner for Availability
Telkom retains its only victory in the award table, for Availability. Our Telkom users connect to 3G or better services 97.9% of the time — the best result in South Africa. This is around 2.8 percentage points higher than on MTN and Vodacom’s network, which are in a statistical tie for second place. Meanwhile, MTN defends the other availability award — 5G Availability — with a score of 8.7%, while Vodacom wins 4G Coverage Experience outright with a score of 7.3 points on a 10-point scale.
Vodacom keeps both consistency awards in a firm grip
Vodacom wins both consistency awards for the second time in a row in Opensignal reports. It scores 64.5% for Excellent Consistent Quality (HD video, group video conference calls, and gaming) and 77.5% for Core Consistent Quality (lower performance applications including SD video, voice calls, and web browsing). These scores reflect the percentage of users’ tests in which the operator met the minimum recommended performance thresholds. For Excellent Consistent Quality, it beats second-placed MTN by 5.5 percentage points, while for Core Consistent Quality, Vodacom commands a lead of 3.7 percentage points over runner-up Telkom.
Mobile Experience Awards
Market Overview
We observe a two-horse race for mobile network experience awards in South Africa. Vodacom and MTN win seven and five awards outright, respectively, and both operators share two additional trophies together, out of 15 awards available. Vodacom wins 5G Video Experience and 5G Download Speed outright for the first time while retaining both consistency trophies, two out of three overall experiential awards (Games Experience and Voice App Experience) and 4G Coverage Experience.
MTN remains the winner of both overall speed awards, 5G Upload Speed and 5G Availability. At the same time, it adds a sole victory for 5G Games Experience to its haul for the first time. Telkom secures its only outright win for Availability, white Cell C ends with no awards this time around. Only two operators in South Africa — MTN and Vodacom — are reportable for 5G metrics — but it is worth mentioning that in December 2022, Telkom rolled out 5G in limited areas as part of its wireless broadband offering.
South Africa’s Ministry of Communications and Digital Technologies proposes switching off 2G by June 2024 and 3G in March 2025 — with activation of new 2G and 3G devices to be prohibited six months before these deadlines, respectively. The Ministry has also published a draft policy document on spectrum trading, sharing and sub-letting. The document also puts limitations on spectrum hoarding — any licensed spectrum unused for more than two years might be revoked by the Ministry. Speaking of mobile spectrum — the digital TV switchoveris planned for the end of March 2023 and its completion is essential for mobile operators to get access to the 700MHz and 800MHz spectrum that they purchased during the auction last year.
In this report, we have analyzed the mobile network experience for South Africa’s four operators — Cell C, MTN, Telkom, and Vodacom — over the 90 days starting November 1, 2022, and ending January 29, 2022, to see how they fared.
Overall Experience
National Analysis
In the previous report, Vodacom took the top spot for Video Experience. This time, however, both MTN and Vodacom are joint winners of this award, with statistically tied scores in the 47.2-49 points range on a 100-point scale. Cell C and Telkom are in a statistical tie for third place, with scores of 37.3-39.7 points.
In Video Experience — 5G Users, MTN and Vodacom tie with identical scores of 56.7 points, placing in the Fair (48-58) category. This means our 5G users are, on average, able to stream video at 720p or better with satisfactory loading times and substantial stalling. 5G users saw their overall video experience scores improve by 7.7 points for Vodacom and 9.5 points for MTN, compared to the overall scores seen by our users on average.
Definitions
Opensignal’s Video Experience quantifies the quality of video streamed to mobile devices by measuring real-world video streams over an operator's networks. The metric is based on an International Telecommunication Union (ITU) approach, built upon detailed studies which have derived a relationship between technical parameters, including picture quality, video loading time and stall rate, with the perceived video experience as reported by real people. To calculate video experience, we are directly measuring video streams from end-user devices and using this ITU approach to quantify the overall video experience for each operator on a scale from 0 to 100. The videos tested include a mixture of resolutions — including Full HD (FHD) and 4K / Ultra HD (UHD) — and are streamed directly from the world’s largest video content providers.
In addition to Video Experience, we report on the following metrics related to video experience:
- 5G Video Experience: The average Video Experience of Opensignal users when they were connected to an operator’s 5G network.
- Video Experience – 5G Users: The average Video Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G video experience along with the availability of each technology.
- 4G Video Experience: The average Video Experience of Opensignal users on an operator's 4G network.
- 3G Video Experience: The average Video Experience of Opensignal users on an operator’s 3G network.
National Analysis
Vodacom remains the sole winner of Games Experience, with a score of 34.1 points on a 100-point scale. It commands a lead of 0.8-1 point ahead of the remaining South African operators statistically tied for second place, with scores of 33.1-33.3 points. All operators in South Africa place in the Very Poor (under 40) category.
Previously, Vodacom commanded a lead of around 1.5 points ahead of MTN and Telkom, which tied for second place — but Vodacom’s winning margin has declined, due to its score dropping by 1.1 points. Due to an increase of 0.8 points in its score, Cell C has moved from fourth to second place, which it now shares with MTN and Telkom.
Looking at Games Experience — 5G Users, MTN and Vodacom are in a statistical tie, with scores in the 34.8-35.1 points range. Our 5G users saw minor, yet statistically significant, increases in their overall scores — 1.8 points for MTN and 0.7 points for Vodacom — compared to all users.
Definitions
Opensignal’s Games Experience measures how mobile users experience real-time multiplayer mobile gaming on an operator’s network. Measured on a scale of 0-100, it analyzes how our users’ multiplayer mobile gaming experience is affected by mobile network conditions including latency, packet loss and jitter.
Games Experience quantifies the experience when playing real-time multiplayer mobile games on mobile devices connected to servers located around the world. The approach is built on several years of research quantifying the relationship between technical network parameters and the gaming experience as reported by real mobile users. These parameters include latency (round trip time), jitter (variability of latency) and packet loss (the proportion of data packets that never reach their destination). Additionally, it considers multiple genres of multiplayer mobile games to measure the average sensitivity to network conditions. The games tested include some of the most popular real-time multiplayer mobile games (such as Fortnite, Pro Evolution Soccer and Arena of Valor) played around the world.
Calculating Games Experience starts with measuring the end-to-end experience from users’ devices to internet end-points that host real games. The score is then measured on a scale from 0 to 100.
In addition to Games Experience, we report on the following metrics related to games experience:
- 5G Games Experience: The average Games Experience of Opensignal users when they were connected to an operator’s 5G network.
- Games Experience – 5G Users: The average Games Experience of Opensignal users with a 5G device and a 5G subscription across an operator's networks. It factors in 2G, 3G, 4G and 5G games experience along with the availability of each technology.
- 4G Games Experience: The average Games Experience of Opensignal users on an operator's 4G network.
- 3G Games Experience: The average Games Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.

Looking at Upload Speed Experience — 5G Users, our MTN 5G users enjoyed over 50% faster upload speeds compared to the average users of the network. The uplift for our 5G users on Vodacom’s network is more modest, of nearly 20%.
Definitions
Upload Speed Experience measures the average upload speeds for each operator observed by our users across their mobile data networks. Typically upload speeds are slower than download speeds, as current mobile broadband technologies focus resources on providing the best possible download speed for users consuming content on their devices. As mobile internet trends move away from downloading content to creating content and supporting real-time communications services, upload speeds are becoming more vital and new technologies are emerging that boost upstream capacity.
In addition to Upload Speed Experience, we report on five supporting metrics related to upload speeds:
- 5G Upload Speed: The average upload speed observed by Opensignal users with active 5G connections.
- Upload Speed Experience – 5G Users: The average upload speeds experienced by Opensignal users with a 5G device and a 5G subscription across an operator’s networks. It factors in 2G, 3G, 4G, and 5G upload speeds along with the availability of each technology.

Our availability metrics are not a measure of a network’s geographical extent. They won’t tell you whether you are likely to get a signal if you plan to visit a remote rural or nearly uninhabited region. Instead, they measure what proportion of time people have a network connection, in the places they most commonly frequent — something often missed by traditional coverage metrics. Looking at when users have a connection rather than where, provides us with a more precise reflection of the true user experience.
We also keep track of the instances that leave mobile users most frustrated: when there is no signal to connect to at all. The most common dead zones users struggle with occur indoors. As most of our availability data is collected indoors (as that’s where users spend most of their time), we’re particularly astute at detecting areas of zero signal.
Our availability metrics take a user-centric, time-based approach that complements the user-centric and geographical-based methodology used by our reach metrics.
Availability shows the proportion of time all Opensignal users on an operator’s network had either a 3G, 4G or 5G connection.

Confidence Intervals
For every metric we calculate statistical confidence intervals indicated on our graphs. When confidence intervals overlap, our measured results are too close to declare a winner. In those cases, we show a statistical draw. For this reason, some metrics have multiple operator winners.
In our bar graphs we represent confidence intervals as boundaries on either sides of graph bars.
In our supporting-metric charts we show confidence intervals as +/- numerical values.
