Turkcell confirms its supremacy in speed metrics, as the operator wins outright both Download Speed Experience and Upload Speed Experience awards once again. Turkcell claims Download Speed Experience with a score of 35.3Mbps, increasing its winning margin over the runner-up Türk Telekom from 7.1Mbps to 10.3Mbps. Our Turkish users observe boosts in their average overall download speeds on all operators, ranging from 2.3Mbps and 2.4Mbps for Vodafone and Türk Telekom, respectively, to 5.5Mbps for Turkcell. Turkcell also leads for Upload Speed Experience, with a score of 13.1Mbps — 2.1Mbps ahead of Türk Telekom. Turkcell and Vodafone’s Upload Speed Experience scores have increased by 0.7Mbps and 0.5Mbps, respectively, while Türk Telekom’s score remained statistically unchanged.
Our Türk Telekom users enjoy the most consistent quality of mobile network services in Türkiye. The operator wins the award with a score of 73.3% — 0.9 percentage points ahead of Turkcell, while Vodafone brings up the rear with a score of 68.5%. 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.
Turkcell defends Video Experience with a score of 64.8 points on a 100-point scale, while Türk Telekom takes the silver medal, with a score 1.9 points lower than the leader’s. All Turkish operators rate as Good (58-68) for video services. Turkcell also wins the newly introduced Live Video Experience award with a score of 58.9 points on a 100-point scale, making it the only mobile operator in Türkiye that places in the Excellent (58 or above) category. Live Video Experience quantifies live video streaming used for current events, such as live sports, game streams, music concerts, or news.
In the previous report, Turkcell became a joint winner for Games Experience along with Türk Telekom which was the sole winner of this award in December 2022. This time around, Türk Telekom claims the Games Experience award all to itself again, with a score of 65.6 points on a 100-point scale, while Turkcell and Vodafone jointly share second place with statistically tied scores of 62.2-63.2 points. Türk Telekom is the only operator in Türkiye to rate as Fair (65-75) — in most cases the game is responsive to the actions of the player with most users reporting that they feel like they had control over the game.
Opensignal’s new Coverage Experience metric measures the extent of mobile networks in the places people live, work, and travel. Turkcell becomes the first winner for Coverage Experience in Türkiye, with a score of 7.1 points on a 10-point scale. Vodafone is the runner-up, 1.2 points behind the winner, while Türk Telekom comes last, with a score of 5.2 points.
Turkcell climbed back on the winners’ podium for Availability in the previous report, sharing the award with Türk Telekom. However, as Turkcell sees a decline in its score of 0.4 percentage points, it drops off the podium again, leaving Türk Telekom there alone with a score of 98.7%. Türk Telekom commands a lead over Turkcell and Vodafone of 0.4 percentage points, as both operators take second place with identical scores of 98.3%. These results reflect the time our users in Türkiye connect to 3G or better services. Both Türk Telekom and Vodafone’s scores remain statistically unchanged since the previous report.
In Opensignal's latest Türkiye Mobile Network Experience report we introduce Live Video Experience which represents the overall of our users when streaming real-time video over mobile networks. Opensignal also introduces the new Coverage Experience metric that measures the extent of overall coverage in the places people live, work, and travel. Consistent Quality replaces the Excellent Consistent Quality and Core Consistent Quality awards used in previous reports.
Turkcell wins five awards outright out of eight recognitions available — it retains both speed awards and Video Experience, while it also claims two newly introduced awards — Live Video Experience and Coverage Experience. Türk Telekom turns two joint wins for Games Experience and Availability into outright victories, as Turkcell slips off the podium for both of these metrics. On top of these two wins, Türk Telekom is the sole recipient of Consistent Quality. For the third time in a row, Vodafone wins no awards, either outright or jointly.
Our results in this report are based on measurements collected across all major mobile operators in Türkiye – Türk Telekom, Turkcell and Vodafone – over the period of 90 days between August 1, 2023 and October 29, 2023, to see how they fared.
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:
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:
Opensignal's Voice App Experience measures the quality of experience for over-the-top (OTT) voice services — mobile voice apps such as WhatsApp, Skype and Facebook Messenger — using a model derived from the International Telecommunication Union (ITU) approach for quantifying overall voice call quality and a series of calibrated technical parameters. This model characterizes the exact relationship between the technical measurements and perceived call quality. Voice App Experience for each operator is calculated on a scale from 0 to 100.
In addition to Voice App Experience, we report on the following metrics related to voice app experience:
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:
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:
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.
The coverage maps show the locations where we received measurements from users connecting with 3G or better mobile service. Each map provides an indication of the areas in which it is possible to obtain mobile service from that mobile operator.
4G Coverage Experience measures how mobile subscribers experience 4G coverage on an operator’s network. Measured on a scale of 0-10, it analyzes the locations where customers of a network operator received a 4G signal relative to the locations visited by users of all network operators.
In simple terms, 4G Coverage Experience measures the mobile coverage experience in all the locations that matter most to everyday users — i.e. all the places where they live, work and travel. It considers all the areas that Opensignal users visit, the portion of locations that 4G is available to them, and locations that more users visit have higher importance to them.

Consistent Quality measures how often users’ experience on a network was sufficient to support common applications’ requirements. It measures download speed, upload speed, latency, jitter, packet loss, time to first byte and the percentage of tests attempted which did not succeed due to a connectivity issue on either the download or server response component.
Full details on how the Consistent Quality metrics — Excellent Consistent Quality and Core Consistent Quality — are calculated can be found here.
Excellent Consistent Quality is the percentage of users’ tests that met the minimum recommended performance thresholds to watch HD video, complete group video conference calls and play games.

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.
