Sunrise offers the best mobile services and the largest 5G network in Switzerland
In the most important telecommunications comparison test in German-speaking countries – the connect mobile-network test (issue 01/2025) – the Sunrise mobile network was again rated «OUTSTANDING» this year. This makes it the only Swiss mobile network to receive this top rating for the ninth time in a row. According to connect, Sunrise offers the best mobile services and the most reliable data connections, the largest 5G network* and the best-quality mobile broadband coverage in Switzerland. The Sunrise mobile network was awarded 973 out of a maximum of 1,000 points, making it one of the world’s top 5 networks, according to connect. The telecommunications provider also stands out thanks to its excellent mobile network coverage: population coverage has been at 99.9% for years. Network stability is equally impressive, with availability consistently at a peak value of 99.9%.
*In the specific 5G network frequencies without Dynamic Spectrum Sharing (DSS).
Sunrise wins in the "Voice" category, offering the best mobile telephony in Switzerland, with the shortest call-connection times and the best voice-transmission quality.
Sunrise is continuously expanding its network
The Sunrise network is «OUTSTANDING». But we don’t want to rest on our laurels. The expansion of 5G and upgrading of the landline network to deliver speeds of 10 gigabytes require huge levels of investment. That’s why Sunrise invests heavily in its network regularly.
Together with Sunrise Business, Swiss Post is driving digital transformation and creating the postal service of the future.
«The award-winning mobile network from Sunrise Business ensures that our employees, scanners and Post buses are connected, right across Switzerland.»

The 3G mobile network is set to be switched off this year. We recommend switching to a 5G-capable mobile phone. As a general rule and whenever possible, it’s good to opt for the latest generation of devices and to install the latest device software (iOS, Android, etc.).
The fifth generation of mobile communications offers plenty of advantages: significantly higher upload and download speeds, low latency and much more. At Sunrise Business, we’ve got a range of offers available for you: 5G-compatible devices and the perfect mobile subscriptions.
Is 5G perhaps already available on your device, but you’ve somehow deactivated it? Maybe even on purpose, to save battery life? Check your phone settings. We recommend that you select «5G automatically» for lightning-fast Internet.
VoLTE stands for Voice over LTE and allows you to make calls via the 4G/LTE mobile network. We’ve noticed that many of our customers have deactivated this function on their 4G devices. Activate VoLTE and benefit from crystal-clear sound quality, fast connection and a significantly reduced dropped-call rate.
You’ve got a 4G mobile phone and are struggling to make calls abroad? Then be sure to activate VoLTE when you’re abroad. But it’s best to make calls via Wi-Fi in countries where VoLTE isn’t available.
If your mobile network quality inside a building isn’t great, we first recommend activating the «Wi-Fi Calling» option. If no Wi-Fi is available, our Business Indoor Coverage solutions are a great option.
If the mobile phone cells are overloaded, the transmission may be interrupted when using video- and audio-calling apps such as WhatsApp, Microsoft Teams, etc. For a better connection, we recommend using the Sunrise services VoLTE or Wi-Fi Calling.
To get the best reception, we recommend using the excellent Sunrise network together with high-performance devices.
Are you looking to upgrade individual devices or planning on renewing your entire device fleet? We can offer you the perfect solution for any situation.
Many Swiss companies rely on the excellent Sunrise mobile network:
