Wi-Fi Calling is a feature provided by the majority of cellular carrier networks, designed to use an available wireless network in conjunction with the cellular network to provide better connection quality during phone calls. You can easily enable Wi-Fi calling on iPhone and there are several benefits to using it over the classic connection.
Firstly, it offers improved sound quality plus it works even in areas with no cellular service as long as there’s Wi-Fi available. There are many indoor and outdoor locations where these conditions apply, even in crowded urban areas so Wi-Fi calling can actually be a life saver.
How to enable Wi-Fi calling on iPhone
As I already said, Wi-Fi calling is generally supported by all the latest iPhone models and most cellular carriers and we’ll show you how to enable it.
Navigate to Settings -> Phone and select ‘Wi-Fi Calling‘ then enable the ‘Wi-Fi Calling on This iPhone‘ option. A dialog will prompt you to confirm your choice. Simply tap on ‘Enable‘ and the terms and conditions, as well as other important information regarding Wi-Fi calling, will be displayed (you’ll need to agree to the terms as well).
Under the ‘Wi-Fi Calling on This iPhone‘ option, you’ll now have another one called ‘Update Emergency Address‘. We recommend you actually do that, as calling over Wi-Fi makes it impossible for responders to acquire your location.
After you enable Wi-Fi calling on iPhone, your carrier’s name will be followed by ‘Wi-Fi’ in the status bar.
There’s another benefit to using Wi-Fi calling, which is the ability to make calls from other Apple devices linked to the same Apple ID as your iPhone’s.
You can enable this option from the Phone menu in the Calls on Other Devices section and select Add Wi-Fi Calling For Other Devices. This will allow you to call via Wi-Fi from your Mac, iPad, iPod or Apple Watch. For iPads and iPods, you’ll also need to open the Settings app on the respective devices go to Calls from iPhone in the FaceTime menu and select Upgrade to Wi-Fi Calling (the process for Mac computers is similar). Also, this works only if the devices are signed into iCloud and FaceTime using your iPhone’s Apple ID.
