Which UK networks offer Wi-Fi Calling?

13th July 2023

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 – although parts of that do now have mobile signal too.

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.

Asda Mobile

Asda Mobile was later to offer Wi-Fi Calling than most networks but it does now, and this should work an any and all phones that are capable of supporting Wi-Fi calling, meaning most recent Android phones and iPhones, and many older ones as well.

To use it, you’ll just have to enable Wi-Fi Calling on your phone’s settings screen, though note that new Asda Mobile customers will have to wait seven days before it’s available to them.

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 various Samsung phones, Google phones, Huawei phones, Sony phones, and more, 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.

For more information on BT Mobile Wi-Fi Calling and a list of phones that might work, head here.


EE also offers Wi-Fi Calling, with no separate apps or accounts involved, so 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.

EE’s Wi-Fi Calling service is available to all customers with a “compatible device,” which presumably just means any phone that is capable of supporting Wi-Fi Calling, which almost all modern smartphones are. However, you can check out EE’s device guides for confirmation of whether a phone will offer Wi-Fi Calling on its network or not.

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 14 range, iPhone 13 range, iPhone 12 range, iPhone 11 range, iPhone 5S, iPhone SE (3rd Gen), 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 S23 range, Samsung Galaxy S21 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, among others.

Lebara supports Wi-Fi Calling but notes that you’ll be notified once it’s enabled on your phone after joining the network.

Then – assuming you have a compatible smartphone, which most modern ones are – you just need to turn on the Wi-Fi Calling toggle in its settings screen.

Lebara doesn’t keep a list of which phones work with Wi-Fi Calling, but it’s likely to be the same selection as Vodafone (detailed further down) as it uses that network’s infrastructure.

To learn more about Wi-Fi Calling on Lebara, head here.


O2 was the last major network to launch a Wi-Fi Calling service, and the network claims that this works on all the 4G and 5G devices that it now stocks.

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.

Sky Mobile

Sky Mobile is one of the more recent networks to offer Wi-Fi Calling and currently it works on many but not all 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 onwards, the Samsung Galaxy S22 range, the OnePlus 10 Pro, and a number of other handsets.

All Talkmobile customers have access to Wi-Fi Calling, as long as they have a compatible device, with the selection of compatible devices likely being the same as on Vodafone, since this network is owned by Vodafone.

Note however that you must be on Android 12 or higher or iOS 15.4.1 or higher. Then, you can just enable the Wi-Fi Calling toggle on your phone’s settings screen.

To find out more about Wi-Fi Calling on Talkmobile, head to the network’s help page and type ‘Wi-Fi Calling’ into the search box.

Tesco Mobile

Tesco Mobile was one of the last MVNOs to activate Wi-Fi Calling, and at the time of writing (July 2023) it’s still in the process of doing so, meaning you might not immediately have access to it, as it’s being activated for customers in stages.

To guarantee Wi-Fi Calling will work, you’ll need to be a Pay Monthly customer with a device bought from Tesco Mobile, and only select devices are guaranteed to support it, with the current selection including the Samsung Galaxy S22 line, the iPhone 13 line, and a number of other phones.

To find the full list and for more details about Wi-Fi Calling on Tesco Mobile, head here.


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

On most modern phones it should work automatically, and it’s available on the majority of recent devices if you’re with Three, though as with a lot of other networks it may not always work if you didn’t purchase your phone from Three.

Virgin Mobile

Virgin Mobile has also started offering Wi-Fi Calling, and it should work with all Wi-Fi Calling compatible phones – which means the majority of modern and mainstream handsets.

As usual though, 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 first need to call Virgin Mobile on 789 and request they activate it, then 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.

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 6S through to the iPhone 14 range, the Samsung Galaxy S22 line and many earlier models, the Google Pixel 6 line, and 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 14 range, the Samsung Galaxy S22 range, 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.
