3G switch off

Mobile phone networks use a number of different technologies, including 2G, 3G, 4G and 5G.

The 3G networks have been around since 2003 and are used to deliver calls, texts, and lower speed data services.

The mobile providers have decided to switch off their 3G networks to make room for the more advanced 4G and 5G services, giving customers faster and more reliable access.

This work started in 2022, and is expected d to be completed by 2024.

Your provider will tell you if you're affected

Your mobile provider will contact you to let you know if you are affected and what steps you need to take. You might also be able to check your device settings to see if it has 4G available - try checking under 'mobile networks' or 'mobile data'.

If you have a newer device, you probably do not need to do anything

If you're already using a newer 4G or 5G device, you shouldn't need to do anything. Some 4G devices might still need a software or settings update to ensure any calls you make use the right network. Your provider will tell you if that's the case and explain how to make the updates needed.

If you have an older device, it will need to be replaced

If you're using an older device that doesn't use 4G or 5G, you'll need to replace it with a new one to access your mobile data. Your provider will be able to help and tell you if this is the case, so look out for any messages they send you. They should give you lots of notice, so you have time to find the right device for you.
