MNOs set timeline for 2G and 3G to be phased out by 2033 under plans to help bring in new telecoms suppliers to build the UK’s 5G networks

  1. The plans include a joint ambition for 35 per cent of the UK's mobile network traffic to be carried over new RAN solutions by 2030
  1. These measures are a key step in providing nationwide security and resilience following Huawei ban.

2G and 3G mobile networks will be phased out of use in the UK by 2033 as part of measures to increase the security of telecoms supply chains and to support a smooth transition to faster mobile networks.

The announcement follows the UK Government’s decision to ban Huawei equipment from 5G networks and the recent introduction of the Telecommunications Security Act. It forms part of the government’s £250 million strategy to build a more competitive, innovative and diverse supply chain for telecoms, to reduce the world’s over-reliance on a few equipment makers.

The government has agreed (see notes to editors) with the UK mobile network operators (MNOs) Vodafone, EE, Virgin Media O2 and Three that 2033 will be the date by which all public 2G and 3G networks in the UK will be switched off.

The plans will free up spectrum - the radio waves used for sending and receiving information - to allow for the mass rollout of 5G and other future networks which will help create huge possibilities for people's lives. These technologies will help power driverless vehicles and drones, immersive virtual and augmented reality experiences, as well as innovations in tech to achieve Net Zero and improve healthcare. The hyper-fast speeds of 5G will also revolutionise internet accessibility on the go.

The government’s £200 million 5G Testbeds and Trials programme is already seeing next-generation networks transform industries - from smart farming to immersive reality experiences to enhancing the UK’s top tourist destinations and 5G buoys helping coastguards save lives at sea.

Digital Secretary Nadine Dorries said:
“5G technology is already revolutionising people’s lives and businesses - connecting people across the UK with faster mobile data and making businesses more productive.
“Today we are announcing a further £50 million to put the UK at the forefront of mobile connectivity and to make sure our telecoms networks are safe and secure now and in the future.  
Hamish MacLeod, Director of Mobile UK, said:
“Mobile UK and its members welcome the government’s statement. Switching off 2G and 3G will enable operators to transition fully to more energy efficient and high capacity networks to the benefit of customers. We are also working with government and wider industry to support the maturity of new RAN solutions to open up further opportunities for innovation and new services in the future.”

In the next step in the tech revolution, the government and MNOs are also announcing new plans to boost innovation and accelerate the rollout of a new wireless communication technology known as Open Radio Access Networks (Open RAN), which enables mobile networks to be built using a variety of different equipment suppliers.

Open networks can feature components from multiple suppliers within one mast site or allow for components to be exchanged or used as replacements at masts that, until now, have been kitted out by a single supplier.

The new plans include a joint ambition for 35 per cent of the UK's mobile network traffic to be carried over new RAN solutions by 2030, £36 million in funding for fifteen projects to trial the technology across Scotland, Wales and England, and a £15 million cash injection for the SONIC prototype testing facility for next-generation telecoms tech.


Sunsetting 2G and 3G  

A current barrier for new suppliers entering the UK’s 5G market is that they must, as it stands, offer 2G or 3G services because they are required by all four domestic mobile operators. Setting out a timeline for winding down these services follows recommendations from the Diversification Taskforce and will allow new suppliers to enter the market by giving them certainty on when they can start work building 5G networks across Britain.

There are wider benefits including reducing the power needed to run multiple networks, being able to reuse spectrum and retiring old kit. It also makes running networks simpler as operators do not have to handle the challenges which arise from managing up to four networks.

Some individual operators will switch off their networks, particularly their 3G networks, earlier than 2033, and will announce their own plans on timing. The number of consumers using 2G and 3G who will need to upgrade is expected to be very low by 2033, and operators have committed to help customers transition to newer network technologies.

Future RAN Competition

It comes as the government reveals the winners of its £36 million competition to fund innovative R&D projects across the UK to develop new RAN technology.

The 15 winning consortiums in the Future Radio Access Network Competition (FRANC )will develop technical solutions - such as radio transmitters, signal processing equipment, power management systems and the software - required to roll out open RAN solutions across the UK quickly and attract  new home-grown telecoms suppliers to the 5G supply chain.

In a boost to levelling up, the investment will be spread across the UK , including Glasgow, Cardiff, Cambridge, Newcastle, Newport, Slough and Ebbw Vale.

Matthew Evans, Director of Markets at techUK, said:

“Today’s announcement of the successful FRANC bids is testament to the role our tech and telecoms sector can play in preparing and empowering the UK’s networks for future prosperity and security. It is a clear indication of the talent, expertise and innovation the UK can offer the global telecoms market.

“While more can be done to accelerate the commercialisation of UK innovation in advanced connectivity, opportunities like FRANC show the willingness of our tech companies, SMEs and academic community in helping deliver the long-term aspirations of secure, resilient, open and disaggregated networks.”

The government is also announcing a cash injection of up to £15 million for SONIC Labs - a test facility based in London and Brighton and run by Digital Catapult with the support of Ofcom to enable telecoms suppliers to test their early stage products in real-world mobile network settings.

SONIC Labs opened in June 2021 with an investment of £1 million. The extra £15 million will be invested so the Lab can expand its programme of testing and international engagement. The new FRANC winners are expected to work closely with the labs.

Joe Butler, Chief Technology Officer at Digital Catapult, said:
"Diversification and interoperability are key themes driving UK capabilities in advanced digital technology and we are pleased to expand Sonic Labs' role in delivering fast, secure and reliable connectivity.

“We look forward to expanding access early next year to our testbed network to companies looking to experiment with and test new products and services. Today's announcement will help us reach more businesses to prepare them for the digital future."

Notes to editors  

  1. Last week both the UK and US endorsed the Prague Proposals on Telecommunications Supplier Diversity, which highlight the importance of working together on research and development with international partners to achieve open and interoperable networks.  
  1. The MNOs are currently taking forward plans to introduce and expand their 5G networks as well working to extend 4G coverage to the most rural parts of the UK. Therefore the 35 per cent ambition is not a mandate and the government will continue to actively support operators and the wider telecoms industry to develop the technologies needed to meet this ambition.

Joint statement with UK mobile network operators

Ambition for the deployment of open and interoperable RAN architectures

The Government is today announcing, together with UK mobile network operators, a joint ambition for 35% of the UK's mobile network traffic to be carried over open and interoperable Radio Access Network (RAN) architectures by 2030.

Open network architectures will play a key role in enhancing the security and resilience of the networks that we rely on - now more than ever - to keep in touch and do business. Following recent decisions the Government has made around the use of high-risk vendors and the introduction of the Telecommunications Security Act, it is right that the Government now sets out its ambitions to build a more competitive, innovative, and diverse supply base for telecoms.  

We recognise that mobile operators are currently taking forward plans to introduce and expand their 5G networks - while also undertaking work to extend coverage to the most rural parts of the UK. Therefore this ambition is not a mandate and instead realising it will require partnership and collaboration between government, mobile operators and the wider telecoms industry.  

We understand that in order to reach this ambition, there is more to be done to develop the performance, economics, and security of new RAN solutions so that they become competitive and viable for scale deployments. Therefore, joint activity will include - investment in the research and development, deployment, and adoption of open network technologies, creating the right market environment to foster and encourage innovation, and international partnerships that bring together learning from across the global supply chain.  

We welcome the forward steps taken by operators and suppliers to position the UK as a leader in the development of open and interoperable RAN technology - and the government has committed £250m of investment to support and accelerate this programme of work.  

This ambition demonstrates the Government's commitment to delivering its Diversification Strategy and building lasting and sustainable supply for the infrastructure that underpins our entire digital economy.

Sunsetting 2G and 3G networks

Finally, following a Diversification Taskforce’s recommendation, the Government has worked closely with industry to establish a date by which all public 2G and 3G networks in the UK will have been switched off.

This next step in the UK’s technological revolution will free up spectrum for 5G and beyond, creating exciting possibilities for our everyday lives and business. The move is also a key step in wider Government measures on introducing new vendors to the UK mobile networks, contributing to nationwide security and resilience.

Establishing this date is necessary to provide much needed clarity as to the likely commercial longevity of these technologies and will enable users to confidently plan for their future. Transitioning away from these technologies will improve network efficiency.

The mobile network operators have confirmed that they do not intend to offer 2G and 3G mobile networks past 2033 at the latest. We welcome that some individual operators will switch off their networks, particularly their 3G networks, earlier than this date, and will announce their own plans about when and how they intend to do this.  

The Government welcomes the responsible switch off of these networks, and will continue to work with network operators to ensure a smooth transition that meets the needs of business users and consumers, including vulnerable groups.
