Key Findings

Our Turkcell users enjoyed the fastest speeds in Turkey

Turkcell remains the sole winner of Download Speed Experience and Upload Speed Experience awards. It triumphs in Download Speed Experience with a score of 31.5 Mbps — 32.1% faster than Türk Telekom and 2.2 times more than third placed Vodafone. Our Turkcell users also experienced the fastest average upload speeds, clocking in at 11.7 Mbps — 1.2 Mbps higher than those on Türk Telekom’s network.

Türk Telekom takes home both Games Experience and Voice App Experience awards

In the previous report, Türk Telekom and Vodafone were joint winners of two experiential awards — Games Experience and Voice App Experience. However, Türk Telekom now wins both awards outright — commanding a lead of four points in Games Experience and 1.4 points in Voice App Experience over second-placed Vodafone. Türk Telekom ended up as the sole winner for both awards due to an increase of 1.6 points for Games Experience, while Vodafone’s scores declined in both metrics.

Turkcell takes away both consistency awards from Türk Telekom

Turkcell snatches both consistency awards away from the previous sole winner Türk Telekom. It claims Excellent Consistent Quality (HD video, group video conference calls and gaming) with a score of 77.5% after a 3.4 percentage point increase, commanding a lead of 0.6 percentage points over Türk Telekom. Turkcell also intercepts Core Consistent Quality (lower performance applications including SD video, voice calls and web browsing) with a score of 90.9% — only 0.2 percentage points ahead of Türk Telekom. These scores reflect the percentage of users’ tests in which the operator met the minimum recommended performance thresholds.

Türk Telekom claims Availability all to itself

Turkcell and Türk Telekom shared the winners’ podium for Availability in the previous report. This time the award goes to Türk Telekom solely — our users connected to 3G or better services 98.5% of the time on this network. Türk Telekom’s score was around 0.5 percentage points higher than Turkcell and Vodafone, which were in a statistical tie for second place.

Turkcell retains the Video Experience and 4G Coverage Experience awards

Turkcell keeps the Video Experience award in a firm grip, as it wins with a score of 55 points on a 100 point scale. Türk Telekom takes the second spot, two points behind the leader, while Vodafone brings up the rear with 43.9 points. Turkcell is the only operator to rate as Good (55-65) for Video Experience, while both Türk Telekom and Vodafone placed in a category below — Fair (40-55). Turkcell also remains the sole winner of 4G Coverage Experience, with a score of 7.1 points on a 10 point scale. This means our users on Tukcell’s network connected to 4G locations in more than seven out of 10 locations they visited.

Market Overview

There are several changes in the awards table in this Turkey Mobile Network Experience report. Compared to the previous report, Turkcell increased its award count from four to six outright wins. It overtook Türk Telekom for both consistency awards and wins them outright — but had to give away Availability as a joint winner to Türk Telekom. Turkcell retained both speed awards, Video Experience and 4G Coverage Experience.

However, Türk Telekom broke out of several statistical ties it was in with its competitors and secures three trophies outright — Availability, Games Experience and Voice App Experience. Vodafone ends with no awards this time around, after slipping off the winners’ podium for two experiential awards it jointly won last time with Türk Telekom, who wins them outright this time around.

Turkish operators are yet to roll out 5G services in the country, however, there are developments in the country that are moving towards these future deployments. Vodafone announced it has completed the virtualisation process of its 2G/3G/4G infrastructure — moving to cloud infrastructure will support the provision of 5G services in the future. Meanwhile, Nokia partnered with the Turkish Employers’ Association of Metal Industries (MEXT) to install a 5G private Digital Automation Cloud system at the MEXT Technology Center, which will connect participating Turkish manufacturers. This cooperation will help to put 5G into an industrial context, ahead of commercial deployments in the country.

Our results in this report are based on measurements collected across all major mobile operators in Turkey – Türk Telekom, Turkcell and Vodafone – over the period of 90 days between August 1, 2022 and October 29, 2022, to see how they fared.

National Analysis

Turkcell retains Video Experience, as it wins it with a score of 55 points on a 100 point scale — two points ahead of the runner-up Türk Telekom. Vodafone comes third, scoring 43.9 points. Both Turkcell and Vodafone observed declines in their scores since the last report, of 1.5 and 2.8 points respectively, while Türk Telekom’s score remained statistically unchanged.

Turkcell is the only operator to rate as Good (55-65) for Video Experience, while both Türk Telekom and Vodafone placed in a category below — Fair (40-55).

A Good rating means an acceptable but inconsistent experience, even from the same video streaming provider and particularly for higher resolutions, with noticeably slow loading times and stalling not being uncommon.

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

In the previous report, Türk Telekom and Vodafone shared the winners’ podium for Games Experience. Türk Telekom successfully broke out of the statistical tie due to an increase of 1.6 points, while Vodafone’s score declined by 2.2 points since the last report. As a result, Türk Telekom claims the award outright with a score of 63.4 points and a winning margin of four points over Vodafone. Turkcell comes last with a score of 55.3 points — but it saw the highest improvement of 4.1 points.

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.

National Analysis

After jointly winning Voice App Experience with Vodafone in the previous report, Türk Telekom is now the sole winner of this award, with a score of 79.6 points. While its score remained statistically unchanged, Vodafone’s result declined by 0.7 points since the last report — which helped Türk Telekom to claim the trophy outright, 1.4 points ahead of Vodafone. Turkcell lags behind its competitors with a score of 75.4 points — however, it was the only operator to see a statistically significant improvement in its score of 1.4 points.

All three Turkish operators placed in the Acceptable (74-80) category. An Acceptable Voice App Experience means some users were satisfied. Perceptible call quality impairments were experienced by some users. Clicking sounds of short duration or distortion were heard, and/or the volume may not have been sufficiently loud. Listeners were generally able to comprehend without repetition.

Definitions

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:

  • 5G Voice App Experience: The average Voice App Experience of Opensignal users when they were connected to an operator’s 5G network.
  • Voice App Experience – 5G Users: The average Voice App 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 voice app experience along with the availability of each technology.
  • 4G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 4G network.
  • 3G Voice App Experience: The average Voice App Experience of Opensignal users on an operator's 3G (e.g. UMTS/HSPA or CDMA 1X EV-DO) network.

National Analysis

Turkcell retains the Download Speed Experience award outright with a score of 31.5 Mbps — the only operator on which network our users observed average download speeds exceeding 30 Mbps. Turkcell’s result was 32.1% faster (7.7 Mbps) than second-placed Türk Telekom’s score of 23.9 Mbps. While Turkcell’s and Türk Telekom’s results remained statistically unchanged since the last report, Vodafone’s users saw a decline in their average download speeds of 0.7 Mbps (4.9%). Vodafone brings up the rear with a score of 14.4 Mbps — less than half of the speed seen on Turkcell’s network.

Definitions

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).

National Analysis

Turkcell increases its lead over second-placed Türk Telekom for Upload Speed Experience from 0.4 Mbps seen in the previous report to 1.2 Mbps this time around. Turkcell defends its Upload Speed Experience trophy with a score of 11.7 Mbps, while Türk Telekom comes second, with a score of 10.5 Mbps. Vodafone takes third place, with a score of 7.1 Mbps — 3.4 Mbps behind second-placed Türk Telekom. Both these operators saw no statistically significant changes in their Upload Speed Experience scores since the previous report, unlike Turkcell.

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).

National Analysis

Turkcell and Türk Telekom were joint winners of Availability in the previous report. This time, Türk Telekom wins the award outright — our users connected to 3G or better services 98.5% of the time on this network. Türk Telekom’s score was around 0.5 percentage points higher than Turkcell and Vodafone, which were in a statistical tie for second place.

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.

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.

National Analysis

Turkcell wins 4G Coverage Experience outright once again, with a score of 7.1 points on a 10 point scale, 0.5 points ahead of second-placed Vodafone. This means our users on Tukcell’s network connected to 4G locations in more than seven out of 10 locations they visited. Türk Telekom trailed behind, with a score of 5.5 points. All Turkish operators observed identical minor increases in their scores since the previous report, of 0.1 points each.

Definitions

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.
