Wi-Fi calling lets you make phone calls using a Wi-Fi connection, which can give you clearer call quality, especially in places where mobile signal is weak or unavailable. If your phone is connected to Wi-Fi, it will automatically connect to our network for calls.
To use Wi-Fi calling, you'll need a smartphone that supports Wi-Fi calls, a stable Wi-Fi connection and a tariff that includes Wi-Fi Calling.
Please keep in mind that right now, Wi-Fi calls are only available within the Germany's Wi-Fi network. When you're abroad, your phone will use the mobile network for calls as usual.
Turning on "Enable Wi-Fi Calls" allows your phone to make calls over Wi-Fi instead of the mobile network whenever you're connected to Wi-Fi. If you don’t enable it, your phone will use the regular mobile network for calls.
Wi-Fi calls are free and included in your tariff! Just a quick note: currently, you can only make Wi-Fi calls within Germany’s Wi-Fi network. When you're outside Germany, your phone will switch to the mobile network for calls as usual.
It all depends on your device — but don’t worry, we'll guide you through it!

If you lose your Wi-Fi connection during a call, your phone will usually switch seamlessly to the mobile network so your conversation continues without interruption. However, if the mobile signal is weak or unstable in your area, the call might get interrupted.
Most modern smartphones support this feature! Typically, Android devices running version 6.0 or higher and iPhones with iOS 10 or above can make Wi-Fi calls. Some tablets and other devices with calling capabilities may also support it — check your user manual for details.
Yes! Your call data is encrypted during Wi-Fi Calls, so your conversations are protected even on public or unsecured networks. Just a quick note: for safety reasons, emergency calls can't be made via Wi-Fi at this time.
