    Frequently Asked Questions

    If you bought your phone from us after 2016, it’s likely that you’ll have 4G Calling – also known as VoLTE – capability. In 2016, we were the first UK operator to use 4G for voice calls, giving you a better-quality experience. 

    You can check if your phone’s 4G Calling capable and how to switch it on in your device settings in our device support hub.

    Older 4G devices might not be 4G Calling compatible. You can check yours on our device support hub. Pick your device then go to Specifications, Network, then 4G Calling.  

    If your phone’s 4G Calling compatible, you need to make sure it’s turned on in your device settings. 

    4G ready devices that aren’t 4G Calling compatible will still be able to send and receive text messages, and use 4G data on a temporary basis – but cannot make calls using our 4G network. 

    Once our 3G network has been switched off, data and text messages won’t work.  

    If you’ve got a 4G data only device, such as a tablet – you’ll stay connected to our 4G network.

    We’re phasing out our 3G network and expect to have it completely switched off by the end of 2024. So, now’s a good time for you to swap to a 4G Calling or 5G device, if you don’t already have one. 

    Got a 3G-only data device such as a tablet or Mobile Broadband? You’ll need to change to a 4G or 5G ready device to stay connected to our network.

    By the time our 3G switch-off is complete - by the end of 2024 - we’ll have enabled 4G in these areas. You can keep up to date on network improvements using our coverage checker.

    3G will continue to be supported in most areas for a little while yet, and we’ll be in touch when we gradually phase it out. If your device isn’t 4G or 5G compatible, it’s worth exploring your options now, rather than when the time comes.

    If you don’t want to upgrade right now, there may be other options – like Pay As You Go available. 

    Get in touch with us at and we’ll check what options are available and help you prepare for our 3G switch off.   

    It may be worth asking friends or family if they’ve got a spare 4G Calling device you could use while deciding what you’d like to do.

    We’re here to help you understand all your upgrade options. You can get in touch with us at

    If you’re worried about how this change might impact you, please get in-touch. We can have a chat about your situation and look to find the right support to meet your individual needs.

    On 8 December 2021, the Government announced that all public 2G and 3G networks will be switched off by 2033 at the latest. However, operators have been encouraged to switch off their networks — particularly 3G networks — earlier than that.

    We want to make sure we’re ready and ahead of the game, so we can free up as much investment as possible for our 4G and 5G network rollout. This will bring you better connectivity and the best possible mobile experience. 

    After 2024, we won’t be able to support any device that relies on 3G only for data and calls. Unfortunately, you won’t be able to connect to our 4G or 5G networks.

    If you’ve got a 3G data-only Mobile Broadband device, it won’t be supported after 2024. So, we’d recommend that you consider upgrading your device

    If you’ve got a 4G or 5G data-only Home or Mobile Broadband device, you don’t need to do anything.

    Pairing your smartwatch with your phone is done using 4G connectivity and 4G Calling is used to make and receive calls on your smartwatch. Our existing 4G network won’t be affected by the 3G switch off. So, you should be able to continue using your smartwatch without any problems.
