The 3G switch-off in the UK was completed early 2026. We understand that this was a smooth process, and Ofcom and the mobile operators have reported no significant negative impacts on consumers.

The 2G switch-off will take place between 2029 and 2033. Ofcom have reported in its Connected Nations 2025 report that there are around 2 million 2G-only mobile users remaining (including 2G-only accessible handsets).

Government is working with the industry to ensure that 2G-only mobile customers are upgraded to 4G and/or 5G devices that support voice calls before 2G is switched off. This includes ensuring that customers are given sufficient notice by their operator to upgrade their devices, and vulnerable consumers are offered additional support where needed.

The Department is also assessing what the impact of the 2G switch-off will be on other use cases across critical sectors through cross-government and sector engagement.

In December 2021, DCMS published a Joint Statement with the UK’s mobile network operators (MNOs) confirming that all 2G and 3G networks would be switched off by 2033 at the latest. We welcome that some individual operators will switch off these networks, particularly 3G networks, earlier than this date. Each MNO is moving at its own pace within this timeframe and since this statement was published a number of operators have announced individual plans for 3G switch off.

We are committed to extending good quality mobile coverage across the UK. In March 2020, the government announced a deal with the MNOs to increase 4G coverage to 95% of the UK landmass.

In 2017, the government also set an ambition for the majority of the UK population to have access to 5G by 2027. This has been met five years early, with basic “non-standalone” 5G - which uses 5G equipment on 4G infrastructure. In our forthcoming Wireless Infrastructure Strategy, we will establish a new ambition for 5G. We will also set out how we will continue to drive 5G deployment across the UK and ensure that UK businesses reap the full benefits of 5G.

There is no explicit regulatory requirement for MNOs to maintain a 2G or 3G network and the government has limited powers to compel operators to maintain, switch off or streamline specific networks. It is for operators to take final decisions on the provision of network services.

MNOs will contact customers to let them know if they are affected and what steps they need to take prior to the switch off of these networks. DCMS officials are working closely with relevant government departments and Ofcom to support this transition away from 2G and 3G networks. The Government welcomes 2G and 3G networks being switched off in a responsible way, and will continue to work with MNOs to ensure a smooth transition that meets the needs of business users and consumers.
