WiFi-Calling: always a connection.

No app. No surcharges. It's as simple as that. Even when there is no mobile network. Even abroad.

Content: Wifi-Calling

Every Wi-Fi router can be your own personal Salt antenna.

Wherever you have a Wi-Fi connection, you can access the Salt network. In your living room, at a party or even in your hotel room, at home or abroad. All on your existing subscription, as if you were in Switzerland. No surcharges. No roaming costs.

What you need to know

Get ready. This is WiFi-Calling.

  • Excellent indoor coverage wherever you have Wi-Fi access. No more worries about signal strength.
  • No fees, no extra costs, no roaming costs. Calls (Incoming, Outgoing) and SMS with WiFi-Calling are billed according to your subscription or deducted from your PrePay balance, just as if you were using Salt's mobile network in Switzerland (MMS not included).
  • No need for an extra app or for the person you're calling to have the same app. WiFi Calling works for all phone numbers, mobile or fixed, all over the world.
  • Your data allowance is not touched because you're using a Wi-Fi network.

All you need is a mobile phone (bought in a Salt Store or on the Salt online shop) that supports this function. To prevent the phone from switching on the mobile network, it is recommended to activate the flight mode.
