UK to Shut Down 2G and 3G Networks by 2033

The United Kingdom will phase out and turn off its 2G and 3G networks by 2033, the British government today announced (via TechRadar).

BT already committed to ending its 3G service by 2023, but now all major carriers in the UK are in agreement to retire 2G and 3G over the next decade. The networks are due to be switched off as part of plans to accelerate the roll out of 5G across the country. The UK government added that the move also paves the way for future 6G services.

While the number of people reliant on 2G and 3G networks is relatively low, retiring them will allow operators to reclaim spectrum to be used in 4G and 5G networks, as well as save money being spent on powering and maintaining inefficient legacy equipment. 2G may remain in use for longer than 3G because it offers wide coverage and comparatively low power requirements which make it ideal for some IoT deployments.

In the United States, carriers have begun a similar process, with Verizon planning to shut down its 3G network on December 31, 2022.

While the original iPhone from 2007 supported 2G networks, the iPhone did not support 3G until the device's second generation. Such was the importance of 3G connectivity to the second-generation iPhone that it was called the "iPhone 3G." The iPhone did not get 4G until the launch of the iPhone 5 in 2012, and the drive toward 5G across the industry did not gather pace until the launch of the iPhone 12 lineup last year.
