We’re making changes to 3G

Futureproofing your device on Three

We’ve noticed you’re using a device that isn’t 4G / 4G Calling (also known as VoLTE) compatible.

Over the coming months, we’re carrying out maintenance and making some improvements to our 4G network in areas where you use your service. However, you may notice a reduction in your coverage if you rely on 3G for data or calls, meaning you may not be able to make and receive calls/texts, or use data, where you’ve previously been able to.

What can you do?

Firstly, check your device compatibility to see if you have a 4G Calling handset, or a 4G mobile broadband device. If you’ve recently upgraded your handset / device, you may not need to do anything, so check compatible devices on our Device Support hub.

If you do have a compatible device with 4G data / 4G Calling, simply double check you’re connecting to 4G via your device settings, using the Device Support hub if you need help on how to do this.

What if I don’t already have a compatible handset or mobile broadband device?

We recommend you consider changing your device to one that is 4G data / 4G Calling compatible. This also means you’ll be future proofed from when we eventually retire all 3G by the end of 2024. We’re not alone in doing this, with other networks in the UK and abroad undertaking similar activity.

There are plenty of options available depending on whether you’re a Pay Monthly or Pay As You Go customer:

Not ready to change your device?

These changes will gradually roll out, so you may not need to change your device right away. However, it’s likely that you’ll experience some level of change over the next few months impacting calls, texts and data. If you’re not ready to make the change to a new device right now, you can hold off and review your network experience.

If you’re facing network issues right away or need special assistance, please contact us.

Why are we doing this?

Throughout 2023 and 2024we’ll be improving our 4G and 5G network, by slowly phasing out 3G through general network maintenance. This helps us make room for a better, faster, and more reliable 4G service experience. Long term, we’ll be completely switching off 3G by the end of 2024.
