Which mobile provider offers the best network coverage in Switzerland in 2026? Whether you are looking for a budget mobile plan or a premium flat rate – network quality determines whether you will be satisfied with your contract or regret it. Based on the nPerf Annual Report 2025 (published in January 2026), here is the updated ranking of Swiss mobile networks.
Network coverage is one of the most important factors – if not the most important – when it comes to choosing a mobile plan for your phone. Some users opt for cheap SIM-only rates from certain providers offering prices below the market average, only to complain later about the lack of signal. So, let’s return to the main question: which mobile provider has the best network coverage? Here is the ranking.
Mobile Coverage Switzerland 2026: The Current Ranking
To evaluate the signal quality of Swiss mobile network operators, we rely on the nPerf report published in January 2026. This report analyzes the state of mobile communications in Switzerland and evaluates various network parameters to determine the best network for a high-quality user experience.
The following ranking is based on the nPerf Annual Report 2025 (01.01.2025–31.12.2025), published in January 2026. Measurement data from over 300,000 daily tests worldwide were analyzed with a statistical accuracy of 1.5%. A ranking is created based on nPerf points, which provide a summary of the various performance parameters collected on the 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 the following categories:
Quality of Service
Overall Experience
5G Experience
Overall Ranking 2025 – nPerf Score (all connections)
Rank | Provider | nPerf Score | Strengths |
🥇 1. | Swisscom | 108,624 | Best download (174 Mb/s), best upload (33 Mb/s), best streaming (81%) |
🥈 2. | Salt | 99,074 | Best latency (26 ms) – ideal for gaming and real-time communication |
🥉 3. | Sunrise | 97,923 | Best navigation (77%), 5G download 249 Mb/s (2nd place) |
Service Quality 2025: Navigation and Streaming Compared
For most users, the quality of service (QoS) is what matters most – not the raw value of the download speed. nPerf measures navigation (loading time of the 5 most visited Swiss websites) and streaming (YouTube loading time in 3 resolutions).
Category | Rank 1 | Rank 2 | Rank 3 |
Navigation (Web) | Swisscom 77.56% | Sunrise 76.88% | Salt 75.18% |
- Peak hours | Swisscom 78.53% | Sunrise 75.23% | Salt 74.77% |
- Off-peak hours | Swisscom 77.06% | Sunrise 77.32% | Salt 75.44% |
Streaming (YouTube) | Swisscom 81.05% | Sunrise 77.27% | Salt 75.55% |
- Peak hours | Swisscom 82.79% | Salt 75.32% | Sunrise 72.85% |
- Off-peak hours | Swisscom 80.44% | Salt 75.81% | Sunrise 78.34% |
What this means: Swisscom leads in 2025 for both navigation and streaming – a shift from 2024, when Sunrise was ahead in navigation. Salt proved surprisingly strong in streaming during peak hours (75.32%), just ahead of Sunrise (72.85%).

Which Virtual Provider (MVNO) has the best coverage?
Virtual mobile network operators (MVNOs) do not own their own network infrastructure but rent capacity from the three network operators. This means: an MVNO's coverage corresponds exactly to the coverage of its host network – no more, no less.
MVNO | Host Network | Coverage corresponds to | 5G included? |
Wingo | Swisscom | Swisscom network: best CH coverage | Yes |
M-Budget Mobile | Swisscom | Swisscom network: best CH coverage | Yes |
TalkTalk | Swisscom | Swisscom network: best CH coverage | Partially |
Yallo | Sunrise | Sunrise network: 2nd place 5G download | Yes |
Digital Republic | Sunrise | Sunrise network: 2nd place 5G download | Yes |
Lebara | Sunrise | Sunrise network: 2nd place 5G download | No |
Lycamobile | Salt | Salt network: best latency (26 ms) | No |
Mucho Mobile | Salt | Salt network: best latency (26 ms) | No |
Important: Equal coverage does not mean equal quality. MVNOs often have priority disadvantages compared to network owners during peak hours – especially regarding download speed and 5G access. You can find details for each provider in our mobile provider comparison.
How do I check mobile coverage at my address?
No ranking can tell you whether your specific location – your home, your workplace, your commute – is well covered. This depends on buildings, topography, and local antenna distribution. There are two ways:
Official provider maps: Swisscom, Sunrise, and Salt offer interactive coverage maps on their websites. Advantage: direct manufacturer source. Disadvantage: you have to visit each website separately.
