Swiss Mobile Providers
Swisscom, Sunrise, Salt and a whole crowd of smaller brands: this guide makes sense of the Swiss mobile market. You will meet the three big telecoms companies that run their own 4G and 5G networks, plus the many virtual operators known as MVNOs (Mobile Virtual Network Operators) that sell plans on top of them. That way you can see who is who and what each of them offers.
Who are the biggest phone providers in Switzerland?
Swiss telecoms revolves around three major operators. They own and run their networks themselves and let other providers (MVNOs) use them for a fee.
The 3 biggest operators that own their networks
Swisscom
Swisscom is the established incumbent and the clear market leader in Switzerland. The Swiss Confederation holds a majority stake of around 51%, which gives the company a special status. It runs the country's largest and densest network, with advanced fixed-line infrastructure (fibre optic, copper) and mobile infrastructure (2G, 3G, 4G, 5G). Swisscom is investing heavily in expanding its fibre optic and 5G+ networks.

Sunrise
Sunrise is the second major player and joined forces with UPC in 2020. It also operates its own mobile and fixed-line network. It competes head to head with Swisscom and has invested heavily in 5G coverage.

Salt
Salt, the third big operator, also has its own mobile network. Historically its coverage was somewhat weaker than Swisscom's and Sunrise's in some areas, but Salt keeps expanding its 5G network. A few years ago it was taken over by French entrepreneur Xavier Niel, founder of the Iliad group (Free). Today Salt's mobile plans are among the most attractively priced on the market.

Swisscom, Salt and Sunrise allow virtual mobile network operators (MVNOs) to use their infrastructure. An MVNO has no network of its own. Instead it agrees a deal with a host operator (Swisscom, Salt or Sunrise) and resells mobile plans under its own brand.
This keeps competition lively in the Swiss market and gives customers more choice, often at lower prices.
Here are a few Swiss MVNOs and the network each one runs on:
On the Swisscom network:
On the Sunrise network:
On the Salt network:
In short: Swiss telecom networks belong mainly to Swisscom, Sunrise and Salt, and all three deliver excellent service. MVNOs enrich the choice and shake up the market with very interesting offers and promotions. Because they run on the Swisscom, Sunrise or Salt networks, their signal quality matches that of the established names. Some of the best mobile deals are often found with these providers, as they price very aggressively.

The quickest way to find the right mobile deal is our independent comparison tool, which takes just a few minutes. Rates change constantly, and at certain moments the best offer is a real bargain. On price, Sunrise and Swisscom are clearly the ones to beat. If you want to pay less, look at the MVNOs or at Salt.
What market share do the mobile providers hold in Switzerland?
Swisscom dominates the Swiss mobile market with a share of 53.1% (end of 2024, source: ComCom/BAKOM). With around 6.4 million mobile customers (end of 2025), it is the country's key player. Sunrise comes second with around 3.2 million customers and a share of 23.6%. Salt ranks third with around 2.3 million customers and a share of 17.7%. All other providers together account for 5.5%.
- Swisscom: Swisscom is the established operator and market leader, with roughly 53% of the mobile market. It is known for its comprehensive network coverage and the quality of its services.
- Sunrise: Sunrise was acquired by Liberty Global in 2020 and has been listed as an independent company on the SIX Swiss Exchange since November 2024. With roughly 24% of the market it sits in second place. Competitive on rates and innovative services, it holds a significant share.
- Salt: Salt used to be called Orange Switzerland and holds roughly 18% of the market. It is valued for attractive and often cheaper offers aimed at a younger, cost-conscious audience.
Besides the three big operators, Switzerland has several mobile virtual network operators (MVNOs) that use their infrastructure for their own offers. These include Wingo, Yallo, Coop Mobile and Migros Mobile. They attract customers with competitive rates and deals tailored to different market segments.
Network quality in Switzerland
Switzerland is known for the high quality of its mobile and fixed-line networks. In coverage and performance they rank among the best in the world.
- Swisscom is regularly rated as having the best mobile network in Switzerland, especially for 5G availability and overall performance (data rates, latency). Its 5G+ network delivers very high speeds.
- Sunrise also offers very good 4G coverage and a steadily growing 5G network that reaches most larger towns and cities.
- Salt has made significant progress in 5G and mobile internet. Compared with its rivals, though, some areas are still less well covered, mainly in rural or mountainous regions.
All three operators are actively pushing 5G rollout across the country, and the quality gap between them tends to narrow over time.
Which Swiss mobile provider has the best network coverage?
It is a tricky question, because in cities the main networks are on a par. You can get 4G or 5G almost everywhere. If you live in a building or house with thick walls, the signal may of course be weaker, and the provider cannot do much about that. Out in the country it is a different story. Most of Switzerland is very well covered, but some regions get less 5G than others. This applies particularly to mountain areas, where a 4G or 5G signal may be missing.
No need to panic: Swisscom, Salt and Sunrise cover over 99% of the Swiss population, and Swiss mobile networks rank among the best in the world for coverage and data transmission.
It is easy to check how good the 4G or 5G signal is where you live. Open the provider's website and go to its "network coverage" page, where an interactive map shows the exact signal quality. You can also find a comparison of coverage across the Swiss providers on the Nperf website.
The bottom line: Swisscom's 5G network has a slight lead over Salt and Sunrise. That gap is likely to shrink over the next few years. The operators are expanding 5G strongly across Switzerland, and more and more customers are ready to use it. In the long run, 5G will replace the existing 4G network and be available everywhere in the country.
