With the switch to 4G and 5G, the outdated 3G network is no longer needed and is therefore being switched off. This will free up capacity for more powerful 4G and 5G networks. You’ll then be ready to embrace the mobile standard of the future. We're making it easy for you to switch – so you can stay connected!
What this means for you:
You need a device that supports at least 4G and VoLTE.
Old SIM cards? If your SIM card isn’t 4G/5G-compatible, we’ll let you know.
Your mobile plan or prepaid rate must include mobile data so that your device can always be connected to the Internet.
No change for newer devices: If your smartphone supports 4G/5G and VoLTE, you’ll automatically benefit from better network quality. Activate VoLTE in your mobile phone’s settings.

Questions and answers
yytr
The continuous growth of mobile Internet-data traffic combined with ever-increasing demands for larger data volumes and decreasing latencies is the main reason why mobile operators are using modern mobile-communications standards such as 4G – and 5G in particular. Compared to the latest technologies, 3G is relatively inefficient and uses a lot more resources, such as bandwidth and electric power, per data unit transmitted.
Voice calls via 3G (including emergency calls)
The mobile-voice-calls service (including emergency calls) will continue to operate via 4G (VoLTE)
Data transmission via 3G
Data will continue to be transmitted via 4G/5G
SMS via 3G
SMS services will continue to operate via 4G. For this to work, the device needs to be VoLTE-capable (exception: 4G is sufficient for devices that just have a data subscription, because it doesn’t require VoLTE)
Circuit-switched data transmission (CSD)
This service with a very low data-transmission rate will no longer be available. Sunrise recommends switching to modern IP-based technologies.
No, the 3G network will be switched off right across Switzerland.
You’ll need to switch to 4G-capable devices (including VoLTE if you need to make voice calls).
Yes, you can keep your phone number, and you’ll also retain your credit if you’re a prepaid customer.
