How to enable Wi-Fi calling on your smartphone

CREDO is on the nation’s best network — there’s no dispute. But we all have those notorious spots in our homes or workplaces where cellular coverage isn’t perfect.

Fortunately, we’ve got you covered. With Wi-Fi calling, you can make and receive calls on a Wi-Fi connection with your existing device and phone number at no extra cost — and it may even improve your call quality at the same time.

In this week’s tip, we’ll walk you through how to enable Wi-Fi calling on your iPhone or Android device.

Before you begin activating your smartphone to use Wi-Fi calling, you must be connected to the CREDO cellular network as well as your home’s Wi-Fi connection and able to connect to the Internet. You will also need your home address, which is required by the FCC and may be used to aid response efforts when you place an emergency 911 call.

If you have a newer smartphone, your device is likely eligible for Wi-Fi calling. Check the settings on your smartphone and search if the Wi-Fi Calling feature is available. For older devices, you may also need to check with the manufacturer to see if HD Voice is available on your device.
