Customers throughout the UK were left without mobile signal, with business secretary Sajid Javid telling the operator to “sort it out”
O2 has told customers that its service is “back to normal” after several throughout the UK complained of a network outage yesterday.
The mobile operator apologised after people in cities including London, Manchester, Bristol and Glasgow as well as parts of Northern Ireland, took to social media to complain they couldn’t make or receive calls, send or receive text messages or access 3G internet signal for up to five hours.
An O2 spokesman said service had been restored at 23:35 BST last night, adding: “We apologise for any inconvenience caused to those customers affected and we will begin a full investigation to identify the root cause.”
Business Secretary Sajid Javid was among those to tweet his frustration to O2, demanding the operator “sort it out”.
In a series of tweets in reply to customers complaining of a loss of service, O2 advised customers to reboot their handsets in an attempt to resolve the issues.
O2 has suffered network outage problems in the past. In October 2012, around 10 per cent of its customers lost access to the network – some for up to four days.
Three months earlier in July, an outage affected around a third of its 23 million customers at the time, leaving them without data services for 24 hours. Affected customers were given a £10 reduction off their next monthly bill, with all given a £10 voucher to spend in one of its stores.
