WiFi Calling

Waiting for an important call and no network? As long as you are connected to a local Wi-Fi network, it doesn't matter. You can simply make the call as a WiFi call. Here you can learn about the advantages of WiFi calling and how you can activate the function in just a few seconds.

Make phone calls via WiFi

The biggest advantage of the Wi-Fi calling function over conventional telephony is that the quality of your calls increases significantly. Thanks to WiFi calling, the reception is much stronger, which is especially beneficial in buildings with thick concrete walls. The call quality is also much better and your calls are established faster.

The person you are calling does not necessarily have to be connected to a Wi-Fi network. It also doesn't matter whether you call a landline or a cell phone number via WiFi.

It is important to know that WiFi calls are billed like regular calls from within the USA - even if you are abroad. Of course, this has an enormous advantage: if you are traveling abroad, you can make calls to the USA with ease and not pay a cent more than at home.

But be careful: If you make a WiFi call abroad and the recipient is not in the USA, it can quickly become expensive. Especially in EU countries, it is advisable to make calls via the good old mobile network. Roaming charges no longer apply in the European Union anyway.

Provider must support WiFi calling

In order to use WiFi calling, not only your smartphone has to support the service, but also your provider. With the big three - Telekom, Vodafone and Telefónica - the feature is included in many rates. Only in some exceptional cases do you have to add WiFi calling as a rate option for a small monthly fee.

By the way: You cannot make emergency calls with WiFi calling. In this case, your smartphone automatically switches to classic cellular mode. The reason: Your location cannot be determined with a WiFi call.
