Thousands of mobile phones will become obsolete this year as the 3G data network is switched off.
Mobile services in the UK currently use four different generations of technology, 2G, 3G, 4G and 5G.
3G networks were launched in 2003 and can be used to send texts, deliver calls, and provide low speed data services.
Mobile providers are switching off the 3G networks in order to make more room for 4G and 5G networks, providing customers with more reliable and faster services.
Networks such as Vodafone and EE have already switched off their 3G network, also affecting customers on Lebara Mobile, Asda Mobile, Talk Mobile, Voxi, Plusnet and more.
Two other major networks will begin switching off their 3G networks soon, with Three switching off their network later this year, and O2 beginning their switch off in 2025.
That will also impact customers with Tesco Mobile, Sky Mobile and Virgin Mobile, who use the O2 network, and iD Mobile and Smarty who use the Three network.
An O2 spokesperson said: “Use of 3G services has fallen significantly, accounting for less than 4% of data use on our network last year. By starting to switch off 3G next year, we can reallocate mobile spectrum to more efficient 4G and 5G services, bringing customers faster data speeds, more reliable streaming and higher-quality voice call services.
“Our priority is to keep our customers connected and the vast majority will not be impacted or have to take any action as we deliver these upgrades. We are committed to providing additional support to those who need it and we’ll be contacting our customers directly ahead of any changes taking place.”
Ofcom has explained the impact this may have on mobile phone users across the UK: “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’re using an older device that doesn’t allow you to use 4G or 5G, you’ll need to get a new one to continue to access your mobile data.
“Again, your provider will tell you if that’s the case, so look out for any messages they send to you. They should give you lots of notice so you have time to find the right device for you.
“If you’re worried that you won’t be able to afford a new device, tell your provider.
“They might be able to offer additional support and help with identifying affordable options. It’s also worth shopping around – there are basic 4G handsets available from as little as £10.”
Ofcom added that mobile providers will contact those who are affected by the switch off and let them know what steps they may need to take.
You can also check your device settings to see if it has 4G capability by checking under ‘mobile networks’ or ‘mobile data’.
