Latest outage, problems and issue reports in Welwyn Garden City and nearby locations:

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • 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

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • 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

    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

  • 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.

  • wokennotwoke ♡ Lauri♡ (@wokennotwoke) reported

    @O2 No you completely fudged up! I was waiting from 9:20 yesterday and couldn’t get in all day! I spoke to o2 who said they was having issues, bottom line is you didn’t give any one a chance they went within seconds for those who had the time to sit and constantly check!

  • RadiationSteve Steve (@RadiationSteve) reported

    @O2 when will you finally honour the prepaid master card promotion that you ran in July? I have phoned multiple times and emailed every scrap of info you have asked for and still no resolve. Terrible service!

  • GregDean5 Greg Dean (@GregDean5) reported

    @O2 Seriously? Your customer service is abysmal! You continue to take my money knowing full well you are not providing the service i pay for! Maybe i charge you for breaking my contract terms and conditions?

  • louiisek1 kelly (@louiisek1) reported

    @o2 on Monday I was assured the order had been cancelled and I would be refunded my deposit. 4 days later no refund and you’ve sent me out the phone I cancelled not the new one I placed after I had cancelled. My new order is on hold because of issues your end and you now want

  • think4urselfpls Diamond Thomas (@think4urselfpls) reported

    @O2 Errrmmm….following the bungle with the app not working this morning, my Greggs treat says it’s been redeemed. Considering I couldn’t even get into the app til now, how is this tomfoolery possible? 🤨 Are there data breaches???

  • JasonSargood Jason Sargood (@JasonSargood) reported

    @O2 Id rather not go now u useless *****. Try providing a service that can be scaled up and out as needed so you can react better to the demand. #o2priorityshambles

  • WillHeslop84 William Heslop (@WillHeslop84) reported

    @O2 All customers should go elsewhere, shocking service - doubt I’ve ever used priority in my 15+ years and the 1 time I’d bite the whole system fell apart

  • spam9i itsspam (@spam9i) reported

    @O2 network f**cking worst in Hamburg. DO NOT USE IT FOR YOUR BROADBAND. Do not!! It’ll be disconnected for every 2 min and come backs like after 10 minutes

  • NTF_Ian Ian (@NTF_Ian) reported from Dunston, England

    Hey @O2 have been waiting almost two hours now to collect my new phone from your metrocentre store. This is not ideal customer service.

  • RobCoombs74 Rob Coombs (@RobCoombs74) reported

    @lisajaneloves @O2 Exactly what I say ,can't run a network and give people what they pay for, let alone try and sell tickets for huge events .Sort it out o2 ,supply decent network coverage and let tickets be sold out through the big boys ,not the wannabes
