TIM wins Consistent Quality outright for a third consecutive time — the only Brazilian operator to win this award since its introduction in the July 2023 mobile network experience report. TIM wins this time with a score of 68.3% and a lead of two percentage points over Vivo and four percentage points over Claro. Consistent Quality measures how often users’ experience on a network is sufficient to support various more demanding common applications used for a range of tasks.
Vivo has moved to the top of the leaderboard for Download Speed Experience after winning it outright with a score of 40.2Mbps. Claro, the previous winner for the last 10 consecutive reports, has moved to second place, 3Mbps behind the leader. Vivo has taken the lead due to its score increasing by 14Mbps from that seen in the previous report, while Claro’s rose by 10Mbps. Additionally, Vivo is once again the outright winner of 5G Download Speed, with average 5G download speeds clocking in at 365.1Mbps. Vivo’s average download speeds are over nine times as fast as its overall download speeds, demonstrating the incredible benefits that 5G networks can provide.
Whether streaming on-demand or live video, our Brazilian users continue to have the best experience on TIM’s network — TIM wins the overall and 5G awards for Video Experience and Live Video Experience outright. TIM commands a one point lead over second-placed Vivo for overall Video Experience and Live Video Experience, scoring 62 points and 54.3 points, respectively. For 5G Video Experience and 5G Live Video Experience, TIM’s respective scores of 76 points and 71.2 points again places it slightly ahead of Vivo.
Claro is the first Brazilian operator to win Opensignal’s Reliability Experience award — Reliability Experience measures the ability of our users to connect to and successfully complete (basic) tasks on operators’ networks. Claro takes home the award with a score of 829 points on a 100-1000 point scale. TIM and Vivo are just behind in second and third place, respectively.
TIM continues to top the scoreboard for the proportion of time its users spend with a mobile connection. TIM wins overall Availability outright — our users on this network connect to 3G or better services 96.5% of the time. For the proportion of time our 5G users spend with an active 5G connection, 5G Availability, TIM now shares the victory with Claro; the pair have identical scores of 13.2%.
As was the case in the previous report, TIM takes home the largest haul of awards, winning seven in total either jointly or outright. TIM continues to provide our Brazilian users with the best experience when streaming video — both on-demand and live — and the most consistent quality of experience. Additionally, TIM is recognised for both Availability and 5G Availability, sharing the latter award with Claro.
Claro has the next largest tally of awards — its five wins including an outright victory for Opensignal’s newly introduced Reliability Experience metric. Reliability Experience measures the ability of our users to connect to and successfully complete (basic) tasks on operators’ networks. Vivo takes home three outright wins, it now wins both awards for download speed — Download Speed Experience and 5G Download Speed — after ending Claro’s winning streak for Download Speed Experience.
Average overall speeds have increased significantly across all three Brazilian national operators since the last mobile network experience report. Upload speeds have risen by 10-20%, while download speeds have shot up by 30-50%. Increased time spent connected to 5G networks is a large contributor to this increase, with users able to benefit from the blisteringly fast 5G speeds more often. Similarly, users’ Consistent Quality scores have risen significantly, by 5-7 percentage points. Opensignal analyzed Brazil’s Consistent Quality at a local level in late 2024 and found the southern states leading the charge on improvements.
The National Telecommunications Agency (Agencia Nacional de Telecomunicacoes, Anatel) has announced that 3.5GHz frequency spectrum has been released for use in 5G standalone deployments across the entire country. The release process has concluded 14 months ahead of schedule and marks a significant milestone in the expansion of 5G in the country. However, while the frequencies may be available in all 5,570 Brazilian municipalities, it does not guarantee the immediate installation of 5G technologies. This is still dependent on the plans of the individual providers. The 3.5GHz spectrum band is key in driving the 5G experience.
In this report we examine the mobile network experience of the three main mobile network operators in Brazil — TIM, Claro and Vivo — over a period of 90 days starting on October 1, 2024, and ending on December 29, 2024, to see how they fared.
TIM once again wins the Video Experience award outright, the third consecutive report in which it has done so. TIM’s score of 62 points on a 100-point scale gives it a lead of one point over Vivo and two points over Claro — the pair place second and third, respectively.
Scores are up across the board for Video Experience in Brazil. Vivo's score has increased by eight points, Claro's by six points and TIM's by four points.
All operators place in the Good (58-68) category. This means that our users are, on average, able to stream video at 720p or better with satisfactory loading times and little stalling.
Video Experience scores account for adaptive bitrate streaming (ABR), a technology that allows Opensignal to accurately represent users' real video experience including video streams up to 4K quality.
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:
TIM retains its outright win for Live Video Experience, doing so this time with a score of 54.3 points on a 100-point scale and a lead of one point over Vivo, which places in second with its score of 53.5 points. Claro comes third with a score of 51.1 points. However, TIM’s lead has shrunk since the previous report due to Vivo’s score increasing by nine points while TIM’s has risen by five points. Additionally, Claro’s score has increased by six points.
TIM and Vivo place in the Very Good (53-58) category, while Claro places one category lower, in Good (43-53).
Operators’ Live Video Experience scores are determined using a range of measures that impact users’ perceived live streaming viewing experience, including picture quality, video loading time, and stall rate, but also live playback offset — the time difference between real-time and the current playback position a viewer sees.
Unlike Video Experience, which represents on-demand video streams, Live Video Experience quantifies live video streaming used for current events. For example when users watch live sports, game streams, music concerts, or news where the event is happening at that moment in time.
Opensignal’s Live Video Experience quantifies the quality of real-time video streamed to mobile devices by measuring video streams over an operator's network. The metric extends the existing International Telecommunication Union (ITU) approach used for Opensignal's on-demand Video Experience metric, built upon detailed studies which have derived a relationship between technical parameters, including live playback offset, picture quality, video loading time and stall rate, with the perceived live video experience as reported by real people. To calculate live video experience, we are directly measuring live video streams from end-user devices and using this extension of ITU's approach to quantify the overall live video experience for each operator on a scale from 0 to 100. The videos tested include a mixture of resolutions and are streamed directly from the world’s largest video content providers.
Claro wins the Games Experience award outright once again. Claro’s score of 65.6 points on a 100-point scale is slightly higher than TIM’s score of 64.4 points. Vivo is right behind TIM, placing third with a score of 64.2 points.
Vivo's score has increased by three points. TIM's and Claro’s scores have increased by one point.
Claro places in the Fair (65-75) category, while TIM and Vivo place one category lower, in Poor (40-65). A Fair (65-75) rating means that users find the experience to be ‘average’. In most cases the game is responsive to the actions of the player with most users feeling like they have control over the game. The majority of players notice a delay between their actions and the outcomes in the game.
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:
Vivo is now the outright winner for Download Speed Experience, ending a multi-report streak of Claro claiming this award. Vivo overtakes Claro with a score of 40.2Mbps, giving it a lead of 3Mbps over the now second-placed operator. TIM’s score of 34.5Mbps places it in third.
Users on all three networks have enjoyed significant boosts in average download speeds since the previous report. Vivo's score has increased by 14Mbps, Claro's by 10Mbps and TIM's by 8Mbps.
Measured in Mbps, Download Speed Experience represents the typical everyday speeds a user experiences across an operator’s mobile data networks.
In addition to Download Speed Experience, we report on the following metrics related to download speeds:
Claro defends its outright win for Upload Speed Experience — an award it has solely won since its introduction to Brazilian mobile network experience reports in January 2019. Claro wins with a score of 9.6Mbps, however, Vivo is right behind with its score of 9.5Mbps. TIM comes third with a score of 8.3Mbps.
Average overall upload speeds on all three operators have increased by 1Mbps since the last report.
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:
TIM keeps hold of the 5G Video Experience award. TIM wins outright with a score of 76 points on a 100-point scale — Vivo is just behind in second with its score of 75.6 points and Claro comes third with a score of 75.2 points.
Since the previous report, Vivo's and Claro’s scores have increased by three points, while TIM's score has increased by one point.
Across all three operators, our users are, on average, able to stream on-demand video at 1080p or better with satisfactory loading times and little stalling. This means that TIM, Vivo and Claro place in the Very Good (68-78) category for 5G Video Experience.
5G Video Experience scores account for adaptive bitrate streaming (ABR), a technology that allows Opensignal to accurately represent users' real video experience including video streams up to 4K quality.

Our Brazilian users have the best experience streaming live video over 5G on TIM’s network. This means that TIM is once again the outright winner of the 5G Live Video Experience award, this time with a score of 71.2 points on a 100-point scale. TIM is one point ahead of Vivo and Claro, which place in second and third, respectively.
Users on all three operators have seen a boost in score, ranging from six points on TIM to eight points on Vivo.
All operators place in the Excellent (58 or above) category. This means that our users are, on average, able to stream video at least at 1080p with low loading times, little stalling and a satisfactory live offset.

5G Live Video Experience quantifies the quality of mobile video experienced by Opensignal users on real-world live video streams when they were connected to 5G.
Vivo is the new outright winner of the 5G Games Experience award — a change from the last report in which Claro won the award. Vivo takes home the gold with a score of 83.2 points on a 100-point scale and a lead of one point over Claro. TIM comes third with a score of 80.7 points, however, the gap between TIM and its peers has shrunk due to Claro’s and Vivo’s scores decreasing, while TIM’s has not changed a significant amount between reports.
All operators place in the Good (75-85) category for 5G Games Experience. This rating means that most of our users deem the experience acceptable. The gameplay experience is generally controllable and the user receives immediate feedback between their actions and the outcomes in the game. Most users do not experience a delay between their actions and the game.

TIM is once again the outright winner of the overall Availability award. TIM’s score of 96.5% is enough to beat Vivo and Claro, which come second and third, respectively.
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.
Claro joins TIM on the winners’ podium for 5G Availability as the pair now share the award with identical scores of 13.2% — Vivo places in third with its score of 12.5%. Claro manages to catch up with TIM due to Claro’s three percentage point boost in score between reports, while users on TIM saw a slightly smaller increase, of two percentage points. Additionally, Vivo’s score rose by five percentage points.

TIM is a third-time winner for Consistent Quality, winning the award outright this time with a score of 68.3% and a lead of two percentage points over Vivo and four percentage points over Claro.
Since the previous report, users’ scores have risen on all three operators, with increases ranging from 5-7 percentage points.
This metric measures if the network is sufficient to support common mobile application requirements at a level that is ‘good enough’ for users to maintain (or complete) various typical demanding tasks on their devices. It assesses a number of experience indicators such as download speed, upload speed, latency, jitter, packet loss, and time to first byte.
Consistent Quality measures if the network is sufficient to support common mobile application requirements at a level that is ‘good enough’ for users to maintain (or complete) various typical tasks on their devices.
We combine different experience indicators such as download speed, upload speed, latency, jitter, packet discard, and time to first byte to calculate Consistent Quality. These components are evaluated against thresholds recommended by various more demanding common applications used for a range of common tasks.
To calculate the metric value, the proportion of tests that pass the requirements of Consistent Quality is multiplied by the test success ratio, which is the proportion of completed tests to all tests conducted. Tests that pass indicate that activities such as video calling, uploading an image to social media, or using smart home applications will be possible without noticeable lag or slowdown.
Claro wins the Reliability Experience award outright with a score of 829 points on a 100-1000 point scale, slightly ahead of second-placed TIM. Vivo comes third with a score of 826 points.
Opensignal’s Reliability Experience measures the ability of our users to connect to and successfully complete (basic) tasks on operators’ networks. It consists of the following components:
% time connected — The proportion of time Opensignal users can successfully connect to a mobile network
Data Connectivity — the proportion of time when the network is available and the device can connect to the internet
Task completion — whether tasks initiated by the user’s device are completed
Sufficiency — The probability that (basic) tasks will be executed sufficiently well for the user
Opensignal’s Reliability Experience measures the ability of Opensignal users to connect to and successfully complete (basic) tasks on communication service providers’ (CSP) networks. It analyzes how much Opensignal users’ experience is affected by the radio access and core network, along with issues that prevent them from connecting to the internet even if they have a connection to their CSP’s network. It also factors in users’ ability to successfully use lower performance applications including SD video, over-the-top voice calls and web browsing.

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.
