Key Findings
Turkcell users continue to see the fastest average overall speeds in Türkiye
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.
Türk Telekom triumphs for Consistent Quality
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 takes home both Video Experience and Live Video Experience
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.
Türk Telekom returns to being the outright winner of the Games Experience award
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.
Coverage Experience goes to Turkcell
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.
Türk Telekom becomes the sole winner of Availability
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.
Mobile Experience Awards
Market Overview
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.
Overall Experience
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.

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.

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.

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:
- 5G Download Speed: The average download speed observed by Opensignal users with active 5G connections.
- Download Speed Experience – 5G Users: The average download 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 download speeds along with the availability of each technology.
- 4G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 4G.
- 3G Download Speed: The average downlink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).
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.
- 4G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 4G.
- 3G Upload Speed: The average uplink speed observed by Opensignal users when they were connected to 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO).

The Opensignal Coverage Experience metric measures the extent of mobile networks in the places people live, work and travel. The metric represents the experience users receive as they travel around areas where they would reasonably expect to find coverage.
Traditional coverage metrics typically estimate either a percentage of land area covered, or a percentage of population covered; often neither will be an accurate measurement of the true user expectation and experience. In many markets there are areas where neither population density nor geographic area reflect the importance of coverage to users. For example, in a large mountain range most users will not expect coverage in the wilderness, but poor coverage in the relatively small area of a ski resort is critical for the enjoyment of a holiday. Estimates based purely on population give undue significance to coverage in the most densely populated areas.
Coverage Experience measures geographic coverage of populated areas and therefore more accurately reflects the coverage expectations and experience of typical users. It can give a result that is somewhat different to traditional estimates based on either geographic or population measures. The metric uses a scale from 0 to 10.
Map Definition
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.
Definitions
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.

Consistency
Definitions
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.

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.
