    @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

  • 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?

  • 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.

  • 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

  • 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

  • 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

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • 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

  • 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

    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.

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • 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

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

    @O2 I need help ASAP please

  • 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 👏.

    @O2 what's going on with your network??? I pay a lot per month and today no data or phone calls would work. Thought it was my phone but tested on on a spare. Constant issues that doesn't seem to be fixed! What service am I paying for????

  • lloydkinsella Lloyd Kinsella (@lloydkinsella) reported

    13/ Still no service. Rang @O2 and a new girl says theres a block on my phone (orly?) and needs to remove it, which she says she does and to again try turning my phone off and on every few hours until the service restores. So far nothing...

  • LaurenSTompkins Lauren Tompkins (@LaurenSTompkins) reported

    @O2 I’m after Sierra Blue and on your website says next day delivery is this actually true? I have one on order but don’t cancel it and be back to having to wait even longer.

  • Mark29071823 Mark (@Mark29071823) reported

    @O2 If it’s linked to o2 no thank you your network is terrible and would give another penny to your company and it’s crappy customer services combined with the worst network quality ever

  • iambenlawrence Benjamin Lawrence (@iambenlawrence) reported

    Hey @O2 I’m not getting any signal in LS20 for the last couple of days. Is there something going on please?

  • lloydkinsella Lloyd Kinsella (@lloydkinsella) reported

    10/ Cut to few hours later, @O2 still hasn't restored my service. Now, ordinarily this would be inconvenient in the short term but manageable, I've usually access to other numbers et al and what's a few days...

  • cctingle C Charlie Tingle 😸☕️❤️ (@cctingle) reported

    @O2 Everywhere :( Dual sim iP, constantly have to switch it back to @ee so I can use data, I just don't know how folks on @o2 manage like this, if o2 was all I had I'd be proper screwed. So slow speed tests time out in built up areas etc, ee, no problems.

  • leeanimalkerr LK (@leeanimalkerr) reported

    @O2 how do I remove 5G from my iPhone 12. My signal has been terrible since this was switch on last week. I’m in exactly the same location, 5G sim and latest update with no difference.
