No cellular coverage? Make calls with Wi-Fi calling

Wi-Fi calling means you can make phone and receive calls over an existing Wi-Fi connection without the need to download an extra app. It's easy to set up and activate, in addition to a number of other pros.

Better call quality and range

Making calls with a smartphone via classic cellular networks is only possible if are in the reception area of a cellular transmission tower or base station. This can be difficult in rural areas, and even in large cities some walls or ceilings are too big an obstacle for the radio signal. Wi-Fi calling provides the solution: Whether you're in a vacation cottage or your own four walls – if Wi-Fi calling is activated on your smartphone, you can make calls at any time with high voice quality. The prerequisite for this is that your smartphone is located in the Wi-Fi reception area of your FRITZ!Box or FRITZ!Repeater.
