What is Wi-Fi calling?

Not sure what Wi-Fi calling is or how it works? Here’s the Confused.com guide to everything you need to know about Wi-Fi calling, including how to switch it on.

With Wi-Fi calling, you can make calls and send texts over a Wi-Fi connection rather than the 4G or 5G signal you would normally use. Most Wi-Fi networks are compatible with Wi-Fi calling, including your home Wi-Fi and public Wi-Fi, like the kind you might find in a coffee shop.

If you’re somewhere with no signal, like some underground train stations, but you're connected to Wi-Fi, you can still make calls and send texts.

If you’re not sure what 4G or 5G is, check out our 5G guide.

How does Wi-Fi calling work?

When you have Wi-Fi calling switched on, your device will automatically use Wi-Fi if you’re connected to it. Your phone will route the call through the mobile network if the Wi-Fi connection drops.

Wi-Fi calling is also known as internet calling.

How do I set up Wi-Fi calling on my device?

For Apple products:

Go to Settings > Phone > Wi-Fi Calling and toggle the switch on.

You can also go to Settings > Mobile Service > Wi-Fi Calling and toggle the switch on. Both methods do exactly the same thing.

For Android products:

Open the Phone app > More options icon > Settings and toggle the switch on.

For a shortcut, swipe down twice to reveal the Quick settings panel and then tap the Wi-Fi calling button to switch it on.

Does Wi-Fi calling cost money?

Not necessarily. When you use Wi-Fi calling, the call or text is billed by your mobile provider exactly as if you were using a normal 4G or 5G cellular signal. This means the call will deduct  minutes from your existing monthly mobile allowance instead of consuming mobile data. 

If you have unlimited minutes, Wi-Fi calls to standard UK numbers are completely free.

What is the upside of Wi-Fi calling?

• No need for other apps - One of the best bits about internet calling is that you don’t need to install any other apps. All you need to do is switch on Wi-Fi calling in your phone settings.
• Better signal at home - If you live in an area with a weak or spotty network coverage, you could get a better signal when making phone calls. You are also a lot closer to your Wi-Fi router than you are to the nearest mobile phone tower. In some rural areas, you can be up to 10 miles from the nearest mobile phone tower.
• Conserve your battery - When your phone is constantly searching for a network signal, it can drain your battery. But, with Wi-Fi calling, it takes up a lot less battery for your phone to find and connect to a Wi-Fi signal.

What is the downside of Wi-Fi calling?

There are a few downsides to Wi-Fi calling:

• Unreliable signal strength - Wi-Fi calling can be a great option while you’re at home. However, it might not be so good in public settings. If you are somewhere with lots of people, like a café or airport, the quality of your connection might suffer.
• Wi-Fi hotspots are not always available - Although there are many publicly available hotspots in most places, you are not guaranteed to always be within range of one.
• Emergency services tracking – If you dial 999, emergency services might not be able to pinpoint your exact location as accurately as they can through phone masts and GPS.
