Sunrise Wi-Fi Calling

Do you want better reception? We have the solution

Wi-Fi Calling improves your mobile phone reception in enclosed spaces by using a WLAN connection

Your advantages:

  • Better reception in enclosed spaces
  • Make calls and send SMS/MMS messages as usual without having to download another app (Whatsapp, for example)
  • No additional basic fees

Please note: Phone services (calls, SMS/MMS) are billed according to your current rate. Currently, Wi-Fi Calling can only be used in WLAN networks in Switzerland (no roaming available).
