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

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Ealing, England

    @O2 The problem is the phone tries to switch to 5G where there is no coverage here so it results in no signal. That happens everywhere not just W5

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • Sheena81 Sheena Watts (@Sheena81) reported from Kensington, England

    @MoneySavingExp Is this every network? @O2

  • wlcustoms White Lotus Customs (@wlcustoms) reported from Croydon, England

    I was going to hold off until the 23 series... But god damn you @SamsungUK that s22 ultra looks amazing... @O2 what's the deal on refresh as I'm rolling with the s21 ultra currently?

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • The_United_Lion Stephen ☘️🦁🐝 (@The_United_Lion) reported from Chesham Bois, England

    Hey @O2 is there any way of claiming some money back as we’re into a second week of service disruption due to the works going on in HP5. I’ve had little to no text/voice access unless connected to my home (or public) WiFi for the best part of 5/6 days now.

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 Yeah roam freely in Europe but beware going anywhere else, they wanted to charge me DAILY, the same amount that my husband was charged monthly by his network!!! Beware of extreme charges and dreadful customer service

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 @Ofcom how very patronising- your website didn’t work so used the number and paid today! After 20 years of loyalty I will be leaving for another network….dealing with your constant mess ups takes too much time/money- 3 already this year….it’s only April

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 you’ve sent me reminder to pay u for a bill I can not see! I asked for a bill last mnth, as could not view online and nothing? This is on u! U have stopped my service but I wont pay until I have a break down? Bully! If u can send me a ltr, u can send me statement?? @Ofcom

  • imjoseabreu Jóse (@imjoseabreu) reported from Lambeth, England

    @O2 why so many connectivity issues 4G/5G in Lambeth?!!! I mean we are central London zone 1-2?!! How come the service is so bad here?!

  • AddingtonSteph Stephanie Addington (@AddingtonSteph) reported from Richmond, England

    .@McAfee and @O2 help. Keep getting 404 error when trying to log into the McAfee app.

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • FatimaDuerden Fatima Duerden 🇪🇺 (@FatimaDuerden) reported from Camberwell, England

    My 4G is down. Only Wifi working. @O2 is there a problem??

  • carboncoach Dave Hampton 🌍🌳 (@carboncoach) reported from Kensington, England

    Dear @EE It’s only a few months since I switched to you, but seems I’m gobbling data faster than ever when I was with @O2 Is your metric working? Maybe you’ll say your network is faster? if so I’ll gladly switch back: to my lower data allowance with O2: that I never used up!

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • ANDREWBRUCE1962 Andie..... (@ANDREWBRUCE1962) reported

    @O2 no matter where I go 4G will not work . Never has

  • elstoleno Rachel Bell (@elstoleno) reported

    @O2 Ok. Since your call centre already told me that my details had been sold on, please explain to me how many companies are associating this phone number with a previous bill payer who has never personally used this number?

  • Jason_WB JasonWilkinsonBrown (@Jason_WB) reported

    @O2 One for the network teams. Only happens on 5G in the EC2V 7JE postcode but the connection to WhatsApp keeps dropping. My office is here and has been happening since 5G went live

  • tigertazz Chris Hutchinson (@tigertazz) reported

    @O2 @Apple @o2 extremely long term customer here ….. what can you do for me?🤔

  • Ash_Blakeston Ashley Blakeston (@Ash_Blakeston) reported

    @O2 5G never seems to work when in/around Hull City Centre. Have to turn it off and revert to 4G which works ok. Any reason why please? Thanks

  • SuzannaJackson1 Suzanna Jackson (@SuzannaJackson1) reported

    Hello @O2 can you help me please as your Live Chat has been useless and tried to deflect a billing issue. Thanks

  • elstoleno Rachel Bell (@elstoleno) reported

    @O2 Even just narrow it down for the most recent one 01213140537 called today asking for my mother, who again has only ever been associated with this number via bill payments. The number has a negative mark against it on who called. How do they have this information if not via O2?

  • MungoMungeam Mungo (@MungoMungeam) reported

    @O2 working in Peckham (London) & there’s barely any signal… how can that be???

  • elstoleno Rachel Bell (@elstoleno) reported

    @O2 Like I said, she only paid the bill, her name was never listed anywhere else with this contact number alongside it. The number has been used to join many websites, but always with Rachel as the name. And you can’t have had a data breach or we’d have been informed 🤔

  • Pepsuber88 🅵rank (@Pepsuber88) reported

    @O2 hi, I would like to upgrade my 4g sim to 5g. I've tried to contact your customer service but can't get through to an advisor nor when I'm linked to the website can find the right option.
