O2 'sorry' over 4G outages
O2 has apologised to its millions of customers for 4G network outages that were not expected to be fixed until this morning.
Around 25 million UK customers were left without mobile internet access throughout yesterday as a result of a fault, thought to be caused by Ericsson software, part of which has now been decommissioned.
02 also provides network coverage for providers including Tesco Mobile and Giffgaff, which brought the estimated number of users unable to access 4G to 32 million.
O2 is owned by Telefonica UK, whose CEO Mark Evans said: "I want to let our customers know how sorry I am for the impact our network data issue has had on them, and reassure them that our teams, together with Ericsson, are doing everything we can."
He added: "We fully appreciate it's been a poor experience and we are really sorry."
