UK's BT, which runs EE, says it will phase out 3G by 2023 and plans 5G coverage across the entire country by 2028; iPhone 12 quadrupled 5G traffic since October

Context & Ripple Effects
EE’s 5G strategy began with a six-city launch that preceded Vodafone’s in 2019, then moved into major-city infrastructure work through BT’s Ericsson partnership as the Huawei ban took shape. The new timetable turns that city-led rollout into a network-retirement and nationwide-coverage plan.
The target also sits alongside the UK’s earlier goal of 5G coverage for most of the population by 2025, distinguishing broad population coverage from BT’s stated full-country endpoint.
First-order effects
- BT and EE now have a defined 2023 deadline to retire 3G and a 2028 target for nationwide 5G coverage, concentrating their mobile-network planning on the newer service.
- The reported fourfold increase in 5G traffic since October gives BT a demand signal as it transitions its network away from 3G.
Second-order effects
- EE’s nationwide target raises the competitive benchmark beyond the early-city rollout in which it beat Vodafone to launch, shifting competition toward coverage completion as well as launch timing.
- BT’s existing Ericsson-led build in major cities becomes part of a broader coverage program, increasing the importance of extending network infrastructure beyond those initial locations.
Third-order effects
- If operators pair 3G shutdowns with nationwide 5G buildouts, UK mobile competition will increasingly be organized around retiring legacy generations to fund and operate newer networks rather than maintaining parallel coverage indefinitely.
- The contrast between the UK’s population-coverage objective and BT’s full-country target points to coverage quality and geographic reach becoming separate measures of 5G progress.
The trend: UK mobile networks are moving from early 5G city launches toward legacy-network retirement and broader national coverage commitments.
