How to Activate Wi-Fi Calling on Galaxy S20

Need help utilizing your Galaxy S20’s Wi-Fi calling feature? Here’s a quick guide that’s especially intended for this purpose. Read on to learn how to activate Wi-Fi calling on Galaxy S20 and start making and receiving phone calls using your phone’s wireless internet connection.

Wi-Fi calling is one of the advanced phone app features found in modern smartphones, particularly HD Voice-enabled and Wi-Fi Calling-capable devices like Samsung’s newest Galaxy flagship handset — the Galaxy S20. It’s an HD or High Definition voice service that utilizes a high speed internet connection to process calls. That said, calls are made and received over a Wi-Fi network instead of cellular network.

This feature comes in handy when using your phone in an area where your cellular network coverage is weak or not available at all. Another advantage of Wi-Fi calling is the fact that it doesn’t cost you extra fees for using the service. This is because carriers considered Wi-Fi calls as if you were making regular cellular calling services provisioned for your account. In order to use Wi-Fi calling feature on your smartphone, you will need to enable it beforehand.

If you’re new to the Android platform and need some input on how to get started with Wi-Fi calling on the new Samsung Galaxy S20, I’ve laid out a simple guide for you to use. Feel free to refer to the outlined steps below.

For more information regarding these network preferences, you can ask your carrier or network service provider. There might be some specific requirements to meet in order to use a specific network service.

If for some reason you cannot activate Wi-Fi calling or Wi-Fi calling doesn’t work on your device, check and ensure that you have the HD voice feature activated on your account.  

Before you can add the HD feature to your account, any features that are not compatible with HD voice must be removed. Among these features are ringback tones, call filter, and company name ID, to name some. 

These features must be upgraded to be compatible with HD Voice beforehand. Otherwise, they won’t be available to your line.

HD Voice service is only available for postpaid accounts. It also requires both you and the person you’re calling to be connected to the same cellular network.  

Video calls through Wi-Fi calling can be done through the Contacts app, Video Calling group, Call History logs, within an HD Voice call and Phone app. A one-minute video call usually uses around 6 to 8 MB of data. If the Wi-Fi connection is lost in the middle of a video call, the call will seamlessly transition back to the 4G LTE network.

An indication that your video call is taking place over Wi-Fi is the Phone and Wi-Fi icon showing up on the in-call screen of the video call.

And that covers everything in this guide. Please stay tuned for more comprehensive tutorials, tips and tricks that will help you make the most of your new Samsung Galaxy S20 smartphone.
