O2 customers in some of the UK’s most densely populated areas experienced loss of service yesterday.
Cities most affected included Edinburgh, Glasgow, Belfast, Birmingham, London and Manchester. The problem was first reported at about 4pm, as customers unable to access O2’s network from their mobile devices began inundating the company with complaints.
The telecommunications firm issued an apology later that evening and attempted to reassure customers, explaining that its engineers were looking into the problem “as a priority”.
The company later tweeted: “Some customers may have experienced issues using their mobile.
“This was fixed within 40 minutes, but some customers may experience intermittent issues reconnecting to the network. We’re investigating what happened and we’re truly sorry for any inconvenience caused.”
Some people said O2 customer service agents told them to turn their phones on and off a few times to see if it corrected the problem. Others reported that they could only call people who were not on O2’s network.
It is still unknown what caused the issue, although O2 said it expected normal service to resume soon.
