iPhone: Activate WLAN calls - how it works

You can now use your iPhone to make Wi-Fi calls in areas with poor reception. You have to activate the function - and so far it has only been supported by Deutsche Telekom. From now on, O2 and Vodafone users can also enjoy WLAN telephony.

Wifi calling: Use WiFi calls on the iPhone

With Wifi-Calling you can also make calls over a WiFi connection without or with poor cellular network.

• To use WiFi calls, you need an iPhone 5c or later with iOS 10.1. We'll show you how to update your iPhone manually.
• The function has been available to Telekom customers since iOS 10.
• You may have to obtain updated network operator settings in order to use the function.
• Depending on the provider, you have to book the contract option. At Vodafone, for example, that costs three euros a month.
