The UK O2 mobile phones are back up after millions of customers were locked out of the network triggered by a software problem.
CEO Mark Evans had to apologise to O2’s customers – plus those of a string of other smaller brands that piggy-back on the company’s technology, like Sky, Tesco Mobile, GiffGaff and Lycamobile.
“We can now report that our 4G network has been restored,” said a statement from the firm.
“Our technical teams will continue to monitor service performance closely over the next few days to ensure we remain stable.
But although a software glitch reportedly emanating from tech supplier Ericsson was blamed for the outage, O2 has suffered some serious reputational damage with customers.
Tech giant arrest
O2 is the UK’s second largest mobile network, owned by Telefonica, which also owns Ericsson UK and Ireland.
The network has 32 million customers.
