But an increasing number of phones and carriers are beginning to support Wi-Fi calling too. As its name implies, Wi-Fi calling is a feature that makes it possible to place a call so long as your phone is connected to Wi-Fi. This means if you’re stuck in an area with poor cell reception, you’ll still be able to make a phone call by connecting to a Wi-Fi network.
There’s no need to launch an app or send a request to the recipient like you might have to when using Messenger or Skype, since Wi-Fi calling is integrated directly into your phone. You can place a call as you normally would through your phone’s dialer or contact list.
Not every phone on every carrier supports Wi-Fi calling, but Verizon, AT&T, Sprint, and T-Mobile have guides available online that offer more details on their specific policies. It’s important to note that if you’re using Wi-Fi calling for international calls, fees will likely still apply so check with your carrier.
The video above will show you how to turn on Wi-Fi calling in your iPhone’s settings menu. After following those steps, your carrier may also ask you to enter an address in case a Wi-Fi connection cuts out during an emergency call to 911. When setting up Wi-Fi calling for the first time, you may need to be connected to your carrier’s data network.
