Swisscom has equipped its 4G/LTE data network in Switzerland and the Principality of Liechtenstein for IP telephony (Voice over LTE technology). With the right smartphone VoLTE brings customers an even better voice and telephony experience. Another milestone is WiFi Calling, which aside from surfing also allows you to make calls over any WLAN access.
With WiFi Calling you can make calls over both the mobile and WLAN network. To use WiFi Calling you have to activate it in the Device settings.
No emergency calls with international emergency numbers (112, 911) can be placed via WiFi Calling. We recommend using the fixed or mobile network for emergency calls.
The range of Advanced Calling enabled devices is being continuously expanded.
As soon as you meet the requirements for Advanced Calling, we will notify you per SMS.
VoLTE is automatically enabled. WiFi Calling has to be enabled manually on the device.
