In the coming weeks, O2, the UK's largest mobile phone provider, will “completely shut down” its 3G network.
This change will exclusively impact customers utilizing 3G-only devices, who have likely received notifications detailing their upgrade options.
Delays in transitioning to a newer device equipped with 4G and 5G technology may result in customers losing access to web services.
Currently, only two percent of O2’s mobile data usage stems from 3G, as it can no longer accommodate modern demands.
Discontinuing the service allows O2 to reclaim radio spectrum on its wireless networks, which will enhance speed and improve 4G and 5G coverage.
Numerous other providers have also phased out 3G access in the past few years, including major competitors.
Various trials were conducted during 2025 to ensure a smooth transition for the service shutdown.
Jeanie York, Chief Technology Officer at Virgin Media O2, stated: “We’re now more connected than ever, thanks to substantial investments in faster, more reliable 4G and 5G networks.
“Consequently, 3G has become an outdated technology.
“Our 3G network has already been decommissioned in many parts of the UK, with the remaining areas set to follow soon.
“While a 3G signal may still briefly appear in some locations in early 2026, the network will soon be entirely shut down.
“Anyone still using a 3G-only device should upgrade as soon as possible.”
