O2 investigating network data problems

Our technical teams are investigating.

The mobile network said it had set up an urgent investigation after customers reported being able to get online or use mobile date from the early hours of Thursday. These include subsiduary Giff Gaff, and third party networks, notably GiffGaff, Tesco Mobile, Sky Mobile and Lycamobile. "We are really sorry and working as hard and as fast as we can to fix this".

Affected phones, which may be every single O2 device, simply fail to show any kind of data connection and will not connect even when turned off and back on or when other workarounds are tried, according to users experiencing the problems.

The company is blaming software issues at one of its suppliers for the problems.

Calls are still working, O2 said.

However, some users are reporting that they're also unable to make voice calls or send text messages, so the full scope of the problem is unclear at present. "We apologise for any inconvenience".

United Kingdom customers have reported not being able to use mobile data to access the internet and other services on the company's network.

O2 said it would share further updates as soon as they were available.

The network outage has also affected Transport For London, which uses the O2 network for its electronic timetable displays at bus stops.
