Which mobile operators have the best coverage in Switzerland? Let’s explore together the best mobile operator of 2025, comparing traditional telecommunication companies and virtual operators operating in Switzerland.
Coverage is one of the main factors, if not the most important, when choosing a mobile subscription for your phone. Some users prefer low-cost SIM offers from certain providers, offering various services at prices below the market average, only to later complain about the lack of signal. So, we return to the main question: which mobile operator has the best coverage? Here’s the ranking.
Best Mobile Coverage in Switzerland: Updated Ranking
To rank the quality of the signal from Swiss mobile network operators, we rely on the nPerf report published in January 2025. This report analyzes the state of mobile telephony in Switzerland by evaluating various network parameters to identify the best one for user browsing experience quality.
The nPerf data provides a clear and objective guide to understanding mobile telephony and identifying the best coverage. The study refers to the year 2024 and evaluates mobile networks based on tests conducted via the nPerf app, compiling a ranking based on nPerf points summarizing the various performance parameters collected on Salt, Sunrise, and Swisscom networks.
The official report, titled "Barometer of Mobile Internet Connections in Switzerland" (available on the nPerf website > Publications > nPerf Awards > Switzerland), is divided into several categories:
Service Quality
Overall Experience
5G Experience
The image below summarizes the performance of the best mobile operators in Switzerland according to nPerf across the different evaluated categories.
Service Quality
Analyzing the navigation and streaming service quality, the following results emerge:
Service Quality | Ranking | Details |
Navigation Test |
| Measures the loading time of five popular national websites. This indicator reflects the quality perceived by users. |
Streaming Test |
| Measures the full loading time of a YouTube video at three different resolutions. |
According to the collected data, Sunrise is the best operator for internet browsing quality, while Swisscom leads in video streaming quality.
Overall Experience and 5G
nPerf has also created an overall ranking based on three additional parameters: download speed, upload speed, and latency.
Overall Experience | Ranking | Details |
Download Speed (Mb/s) | Swisscom | Indicates the amount of data the tested connection can receive per second. |
Upload Speed (Mb/s) | Swisscom | Indicates the amount of data the tested connection can send per second. |
Latency (ms) | Sunrise | Indicates the time required for a small data packet to make a round trip between the test device and the measurement server. |
The data for overall experience sees Swisscom excelling in two out of three categories. Combining these results with the above, the ranking is as follows:
Swisscom - 109,352 nPerf points
Salt - 101,285 nPerf points
Sunrise - 100,228 nPerf points
For Swiss 5G-only connections tested:
Swisscom - 125,176 nPerf points
Salt - 116,232 nPerf points
Sunrise - 114,027 nPerf points
How to Check 5G Mobile Coverage
The process for verifying 5G coverage varies by operator. Some operators allow you to check your mobile coverage directly on their official website, while others do not offer this interactive map service. Generally, you can use the free Swiss mobile coverage map available on our website, where you can see 4G or 5G availability for different operators at your address based on nPerf tests.
Which Virtual Mobile Operator Has the Best Coverage?
First, it’s important to note that the network coverage of an MVNO (Mobile Virtual Network Operator) coincides with the network of the supporting MNO (Mobile Network Operator). Virtual mobile service providers do not own antenna infrastructure; instead, they rely on commercial partnerships with existing physical networks. For example, M-Budget Mobile, one of the main MVNOs in Switzerland, uses the Swisscom network and thus offers its customers the same network coverage.
However, having the same network coverage does not necessarily mean accessing the same quality of service or network performance. Typically, MNOs can guarantee better performance both in terms of signal quality and speed, while many virtual operators have limits on 5G usage or allow access to it only by activating a dedicated option.
The above is the best summary on the topic of mobile coverage of the best providers in Switzerland. Instead, to find out how internet providers rank for the best fiber optic coverage, go straight to reading “Fiber Optic Provider Comparison”.
What Is the Fastest Mobile Operator in Switzerland?
nPerf, a leader in internet performance measurement, awarded Swisscom the nPerf Award for mobile performance in Switzerland for two consecutive years (2024 and 2023). According to nPerf tests, Swisscom’s network is the fastest and most efficient in Switzerland, based on global scores derived from individual performance parameters.
Instead, below you will find the average download speed data of the individual networks:
Swisscom: 181.4 Mb/s
Sunrise: 117.4 Mb/s
Salt: 107.2 Mb/s
These, on the other hand, are the average upload speed data:
Swisscom: 32.6 Mb/s
Sunrise: 28.4 Mb/s
Salt: 26.6 Mb/s
Finally, here you will find the average ping latency data:
Salt: 25.4 ms
Swisscom: 28.3 ms
Sunrise: 29.5 ms
