Vodafone began switching off its 3G network in June 2024, marking the start of a nationwide phase-out that will render millions of older phones and devices useless. EE, O2 and Three are expected to complete their own 3G shutdowns by 2025.
The move, backed by the Government, aims to free up radio spectrum for faster 4G and 5G services. While 3G revolutionised mobile internet and video calling, its usage has plummeted as smartphones increasingly rely on advanced networks offering significantly faster speeds and lower latency.
The switch-off will leave owners of 3G-only phones unable to make calls, send texts or access mobile data. Beyond personal devices, the shutdown affects smart meters, personal alarm systems and older vehicle navigation systems. Device owners should check 4G or 5G compatibility with their service providers.
Network operators have contacted customers about the changes, offering upgrade advice and incentives. The Department for Science, Innovation and Technology emphasises the transition's importance for the UK's digital future, highlighting environmental benefits from more energy-efficient networks and potential for innovation.
The UK follows a global trend as telecoms companies optimise networks for future technologies. Industry experts anticipate 2G networks, which still support basic calls and texts, will eventually face phase-out as the country fully adopts next-generation connectivity.
Labour has called for universal access to high-speed connectivity whilst emphasising support for vulnerable customers potentially impacted by digital transitions. The party stresses ensuring no communities are left behind as telecommunications infrastructure modernises.
