Advanced Communication

  • Advanced Communication

    Enjoy communication at its most advanced level.

Rich Communication Services:
Communicate in more than words.

The new global mobile communication standard RCS (Rich Communication Services) enhances SMS with new and varied options. Depending on the device it can be seamlessly integrated into your smartphone messaging function.



RCS will be available for customers of Swisscom, M-Budget, Wingo or Coop Mobile at a later date.


Advanced Calling:
Enjoy telephony at its most advanced level.

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.


The new technology saves your mobile phone battery. You stay in the 4G network permanently and energy-intensive switching to the 3G or 2G network is seldom necessary.

Name display

Names of persons and companies that are listed in the telephone directory are displayed for incoming and missed calls.


You benefit from a consistently high surfing speed, even when making calls. From dialling a number to the phone ringing out takes just two to three seconds.

Voice quality / EV

Enjoy crystal clear voice quality with EVS (Enhanced Voice Service). Calls in full HD audio quality for conversations which offer the same sound experience that you are used to from other digital media. Thanks to the new All IP lines and modern HD Voice fixed-network devices all calls between fixed network and mobile lines support HD voice quality.

Switching between
WLAN and mobile network

You always make calls over the best connection available (4G or Wi-Fi). WiFi Calling is only available in the range of a WLAN. Uninterrupted transition is not guaranteed. Only on the 4G network you can switch without interruption between WLAN and the mobile network.

WiFi Calling

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.


VoLTE allows customers with 4G/LTE-ready smartphones to make calls directly over the 4G/LTE network and not as previously over the 3G or 2G network.

Requirements for Advanced Calling

  • Mobile subscription: All inOne mobile and NATEL® infinity subscriptions
  • A 4G/LTE-enabled device of the latest generation and a software update by the device manufacturer.

Please note:

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.
