THE O2 network has reportedly gone down across the UK this morning.
Furious customers took to social media to flag problems with 4G and data services.
It appears that the network issues appeared about 5.30am.
Customers across Manchester, London and Southampton have all reported outages.
The network confirmed they were investigating.
A statement posted on the company’s website read: “Our technical teams are investigating reports of issues when using data. Voice calls are working OK.
“We apologise for any inconvenience.”
One frustrated customer wrote: “My data is not working neither are my calls. Not connecting and earlier I had no signal at all for about 45 minutes.”
Another added: “Oh great, O2 data network down”.
A third said: “Can I assume there’s a widespread issue with o2 mobile data. Everyone’s off around the country.”
Another pointed out the irony of the company’s response, saying: “Me: My internet isn’t working 🙁
“@O2 : that’s ok, check our website for updates”
The issues also seem to have affected customers with Giffgaff and Tesco Mobile, which both share O2’s network.
The Sun has contacted both providers for a comment but haven’t yet heard back.
It’s not the first time O2’s network has experienced issues.
In October, the mobile network was down leaving thousands of customers unable to make or receive calls.
It also happened in September, as both Sky and 02 mobile networks were down due to Storm Ali.
Meanwhile, EE and Vodafone are being investigated by the watchdog over claims that they gave false information about network coverage in rural areas.
