O2 rapped by Northern Ireland mobile users as phone network goes down
Angry O2 customers in Northern Ireland took to Twitter last night to vent their anger after the mobile phone network's signal went down across many parts of the UK.
Problems were reported in Belfast, Tyrone, London, Manchester, Bristol, Birmingham, Glasgow and Motherwell, as well as many rural areas.
The network told customers who were having trouble with the network to switch their phone off and on again - advice which did little to calm their critics.
Belfast public relations consultant Chris Harrison tweeted: "What's up with O2 in Belfast? Absolutely no signal all the way from Glengormley to Ormeau Road."
SDLP MLA Patsy McGlone said he would be raising the matter with O2 management, and invited customers affected by the outage to email him with details.
O2 customer Aaron Nelson tweeted: "The impersonal, predictable and robotic style of responses from O2's Twitter is an embarrassment. Still learning the internet?"
Even Sajid Javid, the UK's Secretary of State for Business Innovation and Skills was affected by the blackout.
"No signal, O2. Please sort it out," he tweeted last night.
The GiffGaff mobile phone network - which piggybacks on top of the O2 signal - was also badly affected.
O2 said it is looking into numerous reports on social media of problems with its network.
