Place Phone Calls over Wi-Fi (iOS 8)

iOS 8 allows you to configure your iPhone in such a way that you can make calls over a Wi-Fi network. When your iPhone is configured accordingly, you are not required to pay the call charges that you make using your phone, and only the Internet charges become applicable.

To use this, you'll want to be connected to a strong Wi-Fi network with enough bandwidth to handle a voice call. If you can, though, it's likely cheaper than using your minutes.

Assuming that you have your home Internet set up and that your phone is already connected to your Wi-Fi network, here is how to make a voice call over Wi-Fi with iOS 8.

    ■Switch on your iOS 8 device by pressing the Sleep/Wake button.
    ■Slide your finger to the right on the screen (screen with the slide to unlock text) to unlock the device.

    ■On the Home screen, tap the Settings icon.

    ■From the Settings window, tap Phone.

    ■Once the Phone interface appears, under the CALLS section, tap Wi-Fi Calls.

    ■On the Wi-Fi calls window, slide to enable the Allow Wi-Fi Calls toggle button.

    ■From the opened warning box, tap OK to provide your consent.

    ■Once done, you can make phone calls using your Wi-Fi network.

Note: You are required to use the FaceTime app in order make calls using the Wi-Fi network in iOS 8.
