Which UK networks offer Wi-Fi Calling?

3rd June 2021

Wi Fi Calling which networks offer it

Along with VoLTE (Voice over LTE), Wi-Fi Calling is here to upgrade the humble phone call. As the name suggests, it lets you make and receive calls over Wi-Fi, as well as sending and receiving texts over it. That could be handy if you’re somewhere with little or no mobile signal, such as the London Underground, a place which notably has free Wi-Fi available in stations.

EE, Vodafone, O2 and Three each offer Wi-Fi Calling in some form, as do some MVNOs (Mobile Virtual Network Operators), but some offer more options or make it available to more phones than others.

Read on for a rundown of which networks offer Wi-Fi Calling and each network’s approach to it. Note though that in all cases Wi-Fi Calling may not work if you haven't bought your phone directly from the network in question.

BT Mobile

BT Mobile lets all customers, whether on a SIM Only, Family SIM or Pay Monthly Phone plan, use Wi-Fi Calling to both call and text, and it works without an app, so it’s completely seamless.

However, it’s not currently available on all phones. At the time of writing to guarantee it will work you’ll need an iPhone 5S or above on iOS 11.3 or later, or one of a range of Android phones, including but not limited to a Samsung Galaxy S20, Samsung Galaxy S20 Plus, Galaxy S20 FE 4G, Galaxy A12, Galaxy A51, Galaxy A71, Google Pixel 4a, Oppo A72, and Sony Xperia L4, with the latest available software. If using an Android phone you’ll also need to have bought it from BT to guarantee Wi-Fi calling will work.

However, some Android handsets may work whether or not you bought them from BT Mobile.

Whatever handset you’re using, you’ll then need to enable the Wi-Fi Calling toggle in the settings screen for it to work.

Note that BT Mobile claims that it will gradually support more Android phones, but if you have one that it doesn’t list support for or you didn’t buy it from BT Mobile there’s still a chance that it will work, the network just can’t guarantee it.

EE offers true Wi-Fi Calling, which is to say there aren’t any separate apps or accounts involved, instead calls and texts will come through via your standard dialler and SMS apps, they’ll just use Wi-Fi to do so if you’re connected to a Wi-Fi network.

That makes it a seamless experience, which is a big bonus, and calls and texts will come out of your normal monthly allowance. Note however that EE’s Wi-Fi Calling doesn’t work on Pay As You Go.

The only other downside to EE’s Wi-Fi Calling is that it’s not available on all devices, but it is available on a large and ever-growing selection of handsets bought from EE, including the iPhone 12 range, iPhone 11, iPhone 11 Pro, iPhone SE (2020), Samsung Galaxy S21 Plus, Samsung Galaxy S21 Ultra, Galaxy S20 Plus, Galaxy S20 Ultra, Huawei P40 Pro, Huawei Mate 40 Pro and many more.

FreedomPop also offers Wi-Fi Calling. It’s not exactly app-free, but it uses the same app as standard messaging through FreedomPop does, so it’s a fairly seamless experience and it seems to work with all phones that work with the FreedomPop app (which is most of them).

iD Mobile

iD Mobile was one of the first MVNOs to offer Wi-Fi Calling and you’re getting true, app-free Wi-Fi Calling with it.

It’s not available for all phones, but it is available for a lot, including the iPhone 12 range, iPhone 11 range, iPhone 5S, iPhone SE, iPhone 6, iPhone 6 Plus, iPhone 6S, iPhone 6S Plus, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, iPhone XR and a selection of Android handsets, such as the Samsung Galaxy S21 range, Samsung Galaxy S20 range, Galaxy Note 20, Google Pixel 5, Pixel 4 range, Galaxy S10, Samsung Galaxy S10 Plus, Samsung Galaxy Note 10 Plus, Sony Xperia 1, Xperia 1 II, and Huawei P40 Pro.

O2 was the last major network to launch a Wi-Fi Calling service, and it’s currently not available on all handsets, but does work on the likes of the iPhone 12 range, iPhone 11 range, Samsung Galaxy S21 range, Galaxy S20 range, Sony Xperia 5 II, Google Pixel 5, and various other phones.

If you have a supported handset with the latest software then Wi-Fi Calling will be a toggle that you can enable on your phone’s settings screen. After that it will work automatically whenever you’re on a Wi-Fi network. Note also that some Android devices need to be using O2 firmware in order for Wi-Fi Calling to work.

O2 used to also offer an app-driven Wi-Fi Calling service called TU Go, which was an alternative for anyone without a compatible handset, however this has now been discontinued.

Sky Mobile

Sky Mobile is one of the more recent networks to offer Wi-Fi Calling and currently it doesn’t work on a huge number of handsets. At the time of writing you need an iPhone 6 or later with iOS 12.3 or above, or one of a number of Android handsets, including but not limited to a Samsung Galaxy S8 or later, Galaxy Note 10, Galaxy Note 10 Plus, Galaxy Z Fold 2, Sony Xperia 1, Xperia 5, Xperia 10, Huawei P30 or Huawei P30 Pro.

To guarantee it will work you’ll also need to have got your handset from Sky Mobile. You can find out more about Sky Mobile Wi-Fi Calling here.

Smarty Mobile

Smarty Mobile was later to switch on Wi-Fi Calling than many networks, but it offers the service now, and as with most it’s app-free. To make it work, you just need to ensure you have the latest software on your phone, then in most cases you’ll need to enable Wi-Fi Calling on your phone’s settings screen.

However, as with other networks it isn’t compatible with all phones here. Compatible phones include the iPhone 6 through to the iPhone 11 range, the Samsung Galaxy S20 range, the OnePlus 7 Pro, and a handful of other handsets.

Three also offers true, app-free Wi-Fi Calling for calls and texts.

On Android as well as iOS 11.2 and later it works automatically, while those on iOS devices below iOS 11.2 will need to activate Wi-Fi Calling in their phone’s settings screen. Currently it’s available for all iPhones running iOS 10.2 or later, plus the Samsung Galaxy S10, Galaxy S10 Plus, Galaxy S10e, Galaxy S9, Galaxy S9 Plus, Galaxy S8, S8 Plus, Note 9, Note 8, S7, S7 Edge, LG G6 and LG G5 when purchased from Three.

There are also a number of other Android handsets that it will likely work on even if you didn’t get them from Three, as long as you bought them from Europe.

Virgin Mobile

Virgin Mobile has also started offering Wi-Fi Calling, but as with other networks it's only available for a limited number of handsets, including the iPhone 12 range, iPhone 11 range, iPhone SE (2020), and all other iPhones from the iPhone 6 onwards, plus numerous Samsung phones, such as the Galaxy S20 range, and a number of Huawei handsets, including the Huawei P40 Pro.

As usual, Virgin Mobile only guarantees that handsets will work with Wi-Fi Calling if bought directly from the network. To set up Wi-Fi calling you just need to make sure your phone is running the latest software, then turn the Wi-Fi Calling toggle on in its settings screen – if you’re using an Android phone you probably won’t even have to do that last step, as it should work automatically.

Vodafone’s Wi-Fi Calling service is similar to most others, in that it works seamlessly without the need for a separate app. You simply need to have a compatible handset and eligible plan (which most plans are) and then to enable Wi-Fi Calling in the phone’s settings. Once that’s done, you’ll be able to make and receive calls as normal, but over Wi-Fi when available.

Vodafone Wi-Fi Calling is available on the iPhone 12 range, iPhone 11 range, iPhone XS, iPhone XS Max, iPhone XR, iPhone X, iPhone 8, Samsung Galaxy S20 range, Galaxy S10, Galaxy S10 Plus, Galaxy Note 20 range, Google Pixel 5, Pixel 4 range, Huawei P40 Pro and Sony Xperia 1 II among many other devices.

iPhones should work with Vodafone’s Wi-Fi Calling wherever you buy them from, but Android devices in most cases won’t work with it if bought from another network.

VOXI supports Wi-Fi Calling on all the same phones as Vodafone, meaning the likes of the iPhone 12 range, iPhone 11 range, iPhone XS, iPhone XS Max, iPhone XR, iPhone X, iPhone 8, Samsung Galaxy S20 range, Galaxy S10, Galaxy S10 Plus, Galaxy Note 20 range, Google Pixel 5, Pixel 4 range, Huawei P40 Pro, Sony Xperia 1 II and many other devices.

You’ll also need to make sure you have the latest software on your phone and that Wi-Fi Calling is enabled on the settings screen, then it should just work automatically while you’re connected to a Wi-Fi network.
