O2 has confirmed that its 3G and 4G networks are back up and running, following an entire day during which its customers were unable to access data services.
In a statement released in the early hours of Friday, O2 said: “We can now report that our 4G network has been restored. Our technical teams will continue to monitor service performance closely over the next few days to ensure we remain stable.”
Issues first arose early on Thursday, when O2 users took to social media to complain that they were unable to get online using 3G or 4G, with some saying they were also unable to send text messages.
O2 says that the problem, which also affected networks such as Tesco Mobile and giffgaff, was due to faulty software used by Ericsson, which provides infrastructure support for the network.
Ericsson’s UK CEO, Michelle Lindgren, said: “The faulty software that has caused these issues is being decommissioned...Ericsson sincerely apologises to customers for the inconvenience caused.”
With more than 30 million people hit by yesterday’s outage, O2 is likely to have a tough job on its hands winning round disaffected customers who may be looking to switch networks in light of the problem.
There has been no word on whether it will offer compensation.
