U.S. wireless carriers like AT&T, Verizon, Sprint and T-Mobile have supported Wi-Fi Calling for some time now, with AT&T, Sprint and T-Mobile also supporting Wi-Fi Calling on other iCloud-connected devices like iPad, iPod touch, Apple Watch and Mac. According to user reports on MacRumors’ forums, iOS 10.3 beta 1 supports Integrated Calling on Verizon.
With this handy feature, compatible iCloud-signed devices can make and receive calls using your carrier’s account even when your iPhone isn’t nearby.
Wi-Fi Calling on iCloud-enabled devices is supported by other U.S. carriers like MetroPCS and Simple Mobile, as well as by a few global carriers. Verizon customers should be able to take advantage of this useful feature when iOS 10.3 releases publicly.
Apple’s support document lists various iPhone features that carriers in the United States, Europe, Asia and elsewhere currently support, including Wi-Fi Calling, FaceTime, Personal Hotspot and more.
With Integrated Calling, you can use Wi-Fi Calling on other iCloud-connected devices even if your iPhone isn’t on the same Wi-Fi Network or turned on, as long as all devices are signed in to iCloud with the same Apple ID.
This feature, also known as Integrated Calling, requires any iPad or iPod touch model with iOS 9 or later, Apple Watch with watchOS 2 or later, or any Mac model manufactured in 2012 onward with OS X El Capitan or later.
The feature is unavailable on Apple’s mid-2012 Mac Pro desktop.
