The UK's mobile services currently operate across four generations of technology: 2G, 3G, 4G, and 5G. Since 2003, 3G networks have been used for calls, texts, and slower data services. However, mobile providers are now phasing out 3G networks, which may impact customers using older devices. If you have a 4G or 5G device, you likely won’t be affected, though some updates may be needed.

Why are 3G networks being switched off?

3G technology is outdated and less efficient. Providers are discontinuing 3G to focus on faster and more reliable 4G and 5G networks, offering better service to users.

When will 3G networks be switched off?

Each mobile provider has its own schedule for turning off 3G:

• Vodafone: Completed switch-off in early 2024
• EE: Completed switch-off in early 2024
• Three: Switch-off planned by the end of 2024
• O2: Planning to switch off in 2025

These are the UK's four main networks, and smaller companies like Lebara Mobile, Asda Mobile, and Tesco Mobile operate on these networks. Their 3G switch-off timings will align with the larger networks they use.

How will you know if you're affected?

Your mobile provider will notify you if the switch-off affects your device. If you have a 4G or 5G device, you likely don’t need to take action, though some may require a software update for optimal performance.

What if you have an older device?

If your device only supports 3G, you will need to upgrade to a 4G or 5G-compatible phone to continue accessing mobile data. Your provider will notify you if this applies. If you're concerned about the cost of a new device, speak to your provider, as they may offer affordable options. Basic 4G phones can be found for as little as £10.

For customers using older devices on the EE, Vodafone, or O2 networks, calls and texts can still be made via the 2G network, which remains operational. However, the 2G network does not support data services, so mobile data access will be unavailable after the 3G switch-off. Three, which lacks a 2G network, requires users to upgrade to 4G or 5G to maintain service.

Help others who might be affected

Check in with family or friends who may be impacted by the 3G switch-off, and help them understand what steps they need to take.

Buying a new device? Make sure it supports 4G

When purchasing a device, especially from third-party sellers, ensure it supports 4G if you want to access mobile data services. The device information should list the supported networks.

Other devices might be affected too

Certain devices like care alarms, security systems, and payment terminals may also use 3G networks. If you own such devices, contact the supplier or service provider to confirm if an upgrade is needed to keep them functional after 3G is discontinued.

Future of 2G networks

UK mobile providers have committed to shutting down both 2G and 3G networks by 2033. Plans to switch off 2G will likely follow the completion of the 3G shutdowns, though specific dates are yet to be announced.

2G and 3G shutdowns are global

The switch-off of 2G and 3G networks is happening worldwide. In the USA, all 3G networks have already been decommissioned. If you’re traveling to a country where 3G has been switched off, it may affect your ability to make calls or access data unless you're connected to Wi-Fi, particularly with older devices. Check with your provider before traveling.
