Mobile operator EE, which is owned by BT Group, has confirmed that it has switched off its final 3G mobile site as it shifts its network over to newer technology.

The firm said it spent much of last year “phasing out” its customer’s reliance on 3G after completing a pilot switch-off in Warrington.

Since then, it has been methodically retiring the technology across more than 18,000 mobile sites, with time dedicated to pauses in the switch-off so it could monitor the impact on customers.

Rival networks have also started retiring their 3G infrastructure. Vodafone started in June last year in a bid to reallocate some 3G spectrum to 4G and 5G, while Virgin Media O2 plans to retire its network by 2025.
