- O2's 2G networks set to be pulled from 2029 in line with industry
- 4G and 5G networks are more secure and more efficient
- Some IoT and connected systems still use 2G
Virgin Media O2 (VMO2) has become the latest UK mobile operator to announce plans to shut down its legacy 2G networks, beginning in 2029.
At the same time, VMO2 said not having to look after 2G networks will free up more resources to look after, and improve, 4G and 5G network capacity, speeds and reliability.
The company already started shutting down its 3G networks in 2025, with a national cutoff planned as soon as this year, but 2G networks remained open in the meantime.
VMO2 to start pulling 2G networks from 2029
EE is also turning off its 2G networks from 2029, with VodafoneThree following suit in 2030.
While VMO2 promises to warn customers to help them identify affected devices and migrate to more modern networks, most smartphone users are unlikely to notice an impact because modern smartphones rely on 4G and 5G networks instead.
But IoT devices, smart meters, payment terminals, alarm systems and other crucial infrastructure has traditionally used 2G networks.
"While most customers won’t need to take any action at all, some businesses might need to start planning for this now," CTO Jeanie York explained.
The industry-wide 2G shutdown ultimately falls under government plans to strengthen telecoms security, following concerns over supply chain risks, cyberattacks and the general security of critical national infrastructure.
VMO2 also disclosed the environmental benefits of the shutdown. Though its 2G networks only carry 0.5% of all VMO2 mobile network traffic, it accounts for more than 10% of the company’s total cell site energy consumption. The company declared that its 4G and 5G networks are 10x more efficient.
