PHONE company O2 has apologised to customers in the North West who lost coverage for several hours yesterday.
O2 said an investigation into the cause of the problem had been launched.
A spokesman said “some customers experienced some problems accessing our network” and that the service had returned to normal just before midnight last night.
He added: “We apologise for any inconvenience caused to those customers affected and we will now begin a full investigation to identify the root cause.”
Many O2 customers had taken to social media complaining of not being able to send or receive calls and text messages, as well as problems with the 3G internet signal.
O2 said it was continuing to monitor the situation and was working with its suppliers to investigate how the signal failure occurred.
