Engineers are working to fix the issue that has meant customers can not use their mobile data to access the internet and other services on its network.

"Our technical teams are working with their teams to ensure this is fixed as quickly as possible".

The company said one of their third party suppliers has identfied a software issue in their system. It also said that the issue could be causing "intermittent problems" when customers make voice calls too.


O2 customers in Herefordshire are among the 32 million people around the country who are today experiencing problems with the network's 4G and data services, with the website downdetector.uk showing a sudden spike in service issues reported between 5am and 9am this morning.

"We apologise for any inconvenience", the firm said, after problems were first reported at around 5.30am.

It's encouraging users to "use Wi-Fi wherever they can".


The network outage has also affected Transport For London, which uses the O2 network for its electronic timetable displays at bus stops. The outage tool - which allows customers to check if their area is affected - was also down.

TFL said: "The company that updates the data to our network of Countdown Systems is now experiencing difficulties in providing this service".

O2 says it is trying to resolve the issue as fast as possible.


The company, the second-largest mobile network in the United Kingdom, said it was investigating the technical fault.
