Key Findings
Swisscom exceeds the 200 Mbps mark for 5G Download Speed Experience
Swisscom broke out of the statistical tie it was in with Sunrise for 5G Download Speed in the previous report, as it beat the former joint winner by 32.8 Mbps (19%). The operator wins the award outright for the first time with a score of 205.5 Mbps, after a boost of 14.4 Mbps (7.6%) — reaching the 200 Mbps milestone for the first time. With this victory, Swisscom wins all four speed awards outright, as it retains Download Speed Experience, Upload Speed Experience and 5G Upload Speed.
Our Sunrise users connected to 5G services for more than 20% of the time
Sunrise wins one award outright this time around, as it keeps 5G Availability in a firm grip. Our Sunrise users with a 5G device and a 5G subscription connected to 5G services for 20.9% of the time. The operator is also the first in Switzerland to hit the 20% milestone in 5G Availability. Salt and Swisscom place second due to a statistical tie with scores of 16.8-17% — around four percentage points behind the winner. Sunrise also shares the 5G Reach award with Swisscom, with statistically tied scores of 5.8-5.9 points on a 10 point scale.
Our users in Switzerland enjoyed Excellent 5G video experience across all networks
Swisscom defends both of its video awards — Video Experience and 5G Video Experience — beating Salt by 3.2 points for the former and Sunrise by 2.2 points for the latter. All national operators placed in the Excellent (75 or above) category for 5G Video Experience — meaning fast loading times and almost non-existent stalling. Compared to Video Experience, this means one category higher for Swisscom — up from Very Good (65-75) — but two categories higher for Salt and Sunrise.
Salt wins 5G Voice App Experience outright
Salt secures its only outright win with 5G Voice App Experience, scoring 83.6 points on a 100 point scale. Salt commanded a lead of 1.3 points over the runner-up Sunrise and 2.3 points above third-placed Swisscom. All operators rated as Good (80-87) — many users were satisfied, but some experienced minor quality impairments.
Swisscom retains its consistency awards
Swisscom wins both consistency awards for the second consecutive time in Opensignal reports. It claims Excellent Consistent Quality (HD video, group video conference calls and gaming) with a score of 87.1% and Core Consistent Quality (lower performance applications including SD video, voice calls and web browsing) with a score of 93%. These scores reflect the percentage of users’ tests in which the operator met the minimum recommended performance thresholds. Swisscom commands leads of 3.2 and 0.6 percentage points over second-placed Salt, in each respective award.
Swisscom leads for Games Experience, but all operators have tied for 5G Games Experience
In the previous report, Salt took home 5G Games Experience. This time, however, all three operators were in a statistical tie for this award, jointly winning with scores of 84.9-85.8 points on a 100-point scale. Swisscom retains its overall Games Experience award, with a score of 76.8 points. Compared to Games Experience, all Switzerland’s operators saw higher 5G Games Experience scores, ranging from nine points for Swisscom to 15.6 points for Sunrise.
Mobile Experience Awards
Market Overview
Swisscom dominates the awards table as, out of a possible 15 awards, it takes home 10 outright and three shared wins. Our Swisscom users enjoyed the fastest speeds in Switzerland and the operator hit the 200 Mbps mark for 5G Download Speed for the first time ever. Swisscom users also had the most consistent quality of services and connected to 3G or better networks for the highest amount of time in Switzerland. On top of that, Swisscom also garners both Video Experience awards outright along with the overall Games Experience.
Other Swiss operators’ award hauls are more modest, as both Salt and Sunrise both collected one outright and two joint wins each. Sunrise shines in coverage metrics, as it wins 5G Availability outright —the first Swiss operator to reach the 20% milestone — and shares 5G Reach with Swisscom. Salt is still strong in both voice app metrics, as it secures 5G Voice App Experience outright and shares Voice App Experience with Swisscom. All three national operators tied for the remaining category — 5G Games Experience.
Sunrise announced that the sunset of its 2G services will take place at the beginning of 2023, while the 3G shutdown will follow in the next three tofour years. Sunrise’s competitor Swisscom shut down its 2G network in April 2021 and plans to shut down its 3G services in 2025.
Swisscom stated in August to have launched its 5G services using the 3.5 GHz band in 985 locations and 2,230 antennas. On top of this, the operator estimates to have covered 99% of Switzerland’s population with its 5G signal, based on the Dynamic Spectrum Sharing technology. Swisscom also announced a 5G plan for the BMW iX, which BMW claims to be the first 5G car produced by a premium manufacturer, which allows customers to make calls, send messages and browse the Internet via the vehicle’s eSIM, without a need for a smartphone.
Our results in this report are based on measurements collected across all major mobile operators in Switzerland — Salt, Sunrise and Swisscom — over the period of 90 days between August 1, 2022 and October 29, 2022, to see how they measured up.
Overall Experience
National Analysis
Swisscom wins Video Experience outright with a score of 68 points. It commanded a lead of 3.2 points over the runner-up Salt and 6.4 points over third-placed Sunrise. Swisscom was the only operator to place in the Very Good (65-75) category, while Salt and Sunrise rated as Good (55-65). There were no statistically significant changes in all three operators’ scores compared to the previous report.
A Very Good video experience means generally fast loading times and only occasional stalling but the experience might have been somewhat inconsistent across users and/or video providers/resolutions.
Swisscom also scored the highest in Video Experience — 5G Users (71.9 points), but this time, Sunrise and Salt tie for second place with scores of 66-68.1 points. Our 5G users enjoyed Very Good overall video services. Compared to average Video Experience scores for all users, our 5G users observed significantly higher scores, ranging from 4.5 points for Sunrise to 3.2 points for Salt.
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
Swisscom remains the sole winner of the Games Experience award, with a score of 76.8 points — beating second-placed Salt by 1.6 points. Sunrise brings up the rear with a score of 69.3 points and our users on its network observed a decline of 1.8 points in their experience since the previous report. There were no statistically significant changes in Swisscom and Salt’s scores and they remained in the Good (75-85) category, while Sunrise stayed in the category below, Fair (65-75).
A Good gaming experience means that most users deemed the experience acceptable. The gameplay experience was generally controllable and the user received immediate feedback between their actions and the outcomes in the game.
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.

Sunrise trails behind with a score of 75.9 points — 2.1-2.6 points behind the joint winners. All Swiss national operators placed in the Acceptable (74-80) category, meaning some users were satisfied but some experienced perceptible call quality impairments.
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
Swisscom once again wins the Download Speed Experience award. Our Swisscom users enjoyed the fastest average overall download speeds in Switzerland, clocking in at 68.3 Mbps — 15.5 Mbps (29.3%) faster than Salt, and 21.7 Mbps (46.6%) faster than Sunrise. All operators observed increases in their Download Speed Experience scores — with Salt enjoying the biggest increase in absolute terms of 4.7 Mbps, followed by Swisscom (3 Mbps) and Sunrise (2.7 Mbps) when compared with the last report.
Our 5G users also saw the fastest overall download speeds on Swisscom’s network, clocking in at 91 Mbps — 22.7 Mbps faster compared to the overall Download Speed Experience. Sunrise 5G users observed 21.9 Mbps faster speeds than all users on average on this network, while Salt 5G users — 15.3 Mbps.
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.

National Analysis
The Upload Speed Experience award goes to Swisscom once more, as the operator retains it with a score of 18.5 Mbps — 2.4 Mbps ahead of Salt. Sunrise brings up the rear with a score of 14.2 Mbps. None of the operators scores changed by a statistically significant amount when compared with the previous report.
Looking at Upload Speed Experience — 5G Users, Swisscom had the highest score of 19.9 Mbps — 1.4 Mbps more than its Upload Speed Experience score for all users. Salt and Sunrise observed higher differences of 1.5 and 2 Mbps, respectively.
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
Swisscom triumphs in Availability, retaining the award — our users on its network were connected to either a 3G, 4G or 5G connection for 98.8% of the time. Salt and Sunrise remained locked in a statistical tie for second place, with identical scores of 98.2%. No operator saw statistically significant changes in its score since the previous report.
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.

National Analysis
Sunrise wins one award outright this time around, as it keeps 5G Availability in a firm grip. Our Sunrise users with a 5G device and a 5G subscription connected to 5G services for 20.9% of the time. This means the Swiss operator was first to surpass the 20% milestone in 5G Availability, after an improvement of two percentage points compared to the previous report.
Salt and Swisscom placed second after a statistical tie with scores of 16.8-17% — around four percentage points behind the winner. However, both operators observed higher increases in their scores than Sunrise, whittling away the gap between them and the leader. Swisscom’s score increased by 3.9 percentage points — nearly a third of its previous result. Salt’s improvement of 8.1 percentage points was even more impressive, as the operator nearly doubled its 5G Availability score — from 8.7 to 16.8%.

Sunrise and Swisscom remained locked in a statistical tie for the third consecutive time, as they jointly win 5G Reach, with scores of 5.8-5.9 points on a 10-point scale. This means our users on these networks connected to 5G services in nearly six out of 10 locations that matter most to everyday users — i.e. all the places where they live, work and travel.
Salt trailed behind with a score of 4.8 points — 1-1.1 points behind the joint winners. However, it observed the biggest improvement in its score in Switzerland since the previous report, of 1.5 points — compared to 0.5 points for Sunrise and 0.4 points for Swisscom. In relative terms, Salt’s improvement was even more spectacular — 45.5%, while Sunrise and Swisscom saw increases of 9% and 6.7%, respectively.

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.
Why confidence intervals are vital in analyzing mobile network experience
