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.
