Latest outage, problems and issue reports in Northolt and nearby locations:

  • RalphVarcoe Ralph Varcoe (@RalphVarcoe) reported from Merton, England

    @O2 Your own website says there’s a mast down. We had a problem quite a few weeks ago. Zero coverage makes o2 useless.

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • MedinaMadam Eva Hamilton (@MedinaMadam) reported from Camberwell, England

    Not good customer service at all! Maybe you need to join me @O2

  • MissPaulaGreen Paula (@MissPaulaGreen) reported from Camden Town, England

    @O2 I have noticed that the WiFi is not working in 2 locations today 👀🤨

  • KtHob Katie Hobden (@KtHob) reported from City of London, England

    Terrible customer service from @O2 who charged me £40 for data even though my data roaming was off #switchingtovodaphone #callingeverytimeigoabroadisnotpractical

  • tanfish38 Tanya Fisher (@tanfish38) reported from Chesham Bois, England

    3rd day with no signal @O2 🤬

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • jackaarondavies Jack Aaron Davies (@jackaarondavies) reported from Richmond, England

    @O2 Not everywhere, but your 4G coverage in SW London is poor. I haven’t had 4G in Raynes Park since I moved there a year ago.

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • MikeBrownnutt Mike Brownnutt (@MikeBrownnutt) reported from Merton, England

    @O2 Just renewed with you for another 18 months. Your fantastic sales advisor informed me I’ve been a loyal customer for over 8 years. Any chance of sending me something to celebrate our partnership. 🍾🎉

  • Peachey_79 Charlene (@Peachey_79) reported from Wandsworth, England

    @O2 Well after 3 phone calls and the staff in your Wandsworth store trying I was told I couldn’t cancel and had to wait.

  • RalphVarcoe Ralph Varcoe (@RalphVarcoe) reported from Merton, England

    @O2 Can you sort your mast out in Wimbledon please. Totally crap service for weeks and weeks and weeks. Really poor!

  • budgie Lee 'Budgie' Barnett (@budgie) reported from Paddington, England

    @O2 Wasn’t a problem, as such. ‘Kit breaks’ is an ever present rule. Was mainly to let others know,, if they had problems and wondered what was going on.

  • AikSaath Aik Saath (@AikSaath) reported from Slough, England

    @sabia_hussain @SEGROplc @O2 SEGRO have checked to see if the theft was on the estate itself. We'll see the young people right - just thought it might be worth reaching out to our 'bigger cousins' to see if they could help. Good to hear they didn't find anything in your car. 👍

  • oxymoron_tom Tom Bassett (@oxymoron_tom) reported from Wandsworth, England

    Is there a issue in the Earlsfield/Clapham Junction area, consistently been getting speeds of 0.01MB or no data at all @O2

  • Cla_Cottingham Claire Cottingham (@Cla_Cottingham) reported from Wandsworth, England

    @O2 Help. Unfortunately not which I now understand is not ideal!

  • Peachey_79 Charlene (@Peachey_79) reported from Wandsworth, England

    Worse customer service @o2 I give up!

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 after 3 hours of calls 5 texts and 1:5 hours of to get family discount that is advertised and to be given an amount to pay then still getting it wrong . So a complaint to be made

  • davidchow David Chow 📶 (@davidchow) reported from Hammersmith, England

    @MIROFUR Disagree. In the UK it was an exclusive on @O2 as they built out EDGE and turned on support for interactive voicemail. It created a massive influx of people to the base, who continued to stay on even when the 3G version eventually shipped to other carriers.

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • SkyLightStars12 🏴󠁧󠁢󠁳󠁣󠁴󠁿ENOUGH IS ENOUGH🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@SkyLightStars12) reported

    @O2 I didn't get the emergency alert today 😎

  • Searan15 Saeran the Wanderer 💙🇺🇦 (@Searan15) reported

    Why did my phone on @O2 not receive the emergency alert today? Are you investigating why phones did not receive it like @ThreeUK are doing?

  • JordanW59131645 Jordan Watson (@JordanW59131645) reported

    @O2 been waiting nearly a week for my new phone to arrive and it still hasn’t even gotten through “review” yet! i’ve called multiple times with little help received and id like to know when i will receive or whether i should cancel and purchase from elsewhere 😩

  • lmkrun Loop (@lmkrun) reported

    @O2 didn’t get the government alert. Emergency and severe alerts were turned on. Hubby got his from Vodafone and my work mobile on EE got it all on the same table

  • MulierFortis Mulier Fortis (@MulierFortis) reported

    Well, for some reason my phone didn't go off yesterday - and the signal was down to H+ instead of the usual 4G... was this a @giffgaff or @O2 problem in Thanet?

  • thelegalbond Kate Bond (@thelegalbond) reported

    @O2 Should I be concerned that I didn’t get the emergency alert? Alert is switched on in notifications and I’m on 4G/5G signal. I heard this is the same for a lot of other people

  • LauraTaylor937 Laura Taylor (@LauraTaylor937) reported

    @O2 @GOVUK still haven't received my emergency alert... notifications were on and the rest of my household received theirs (my partner at 14:59 my son got his at 15:20) fingers crossed I'm with them if an emergency happens or I'm stuffed!
