    @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?

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

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

    @O2 I need help ASAP please

  • 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

  • LairdDourka Andrew Dourka-Laird (@LairdDourka) reported from London, England

  • 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 👏.

  • 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. 👌👌👌

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • 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

  • 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.

  • 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

    @AliHamidi @O2 Should be on EE the only network covers all the lakes I go 👌👌👌👌

  • wilcochris Chris Wilcox 🌻🇺🇦 (@wilcochris) reported from Peterborough, England

    Hi @O2 Trying to sign in to my account but it’s telling me it has to send a code to continue with my password reset request. This is not what I’m trying to do. Issues with the website or a breach you’re keeping quiet about?

  • collinge_j Jen Collinge (@collinge_j) reported

    @O2 Pretty peed of customer still awaiting for a call informed from a worker on the 13th June to which said a manager would be in contact with 48hrs and a response to written complaint on the 13th June, 7 working days later and still heard nothing! #dataprotectionbreech

  • KennyPowers2008 Kenny (@KennyPowers2008) reported

    @O2 release me from contract you are the worst network provider by a mile, 14 months to fix antenna, your 5g is bullshit as well no gain over 4g

  • HGatchy02 G (@HGatchy02) reported

    @O2 please can you get someone to help my partner. She is trying to move her number over to you. Completed the request online twice and spoken to someone today then got a text to say it's not accepted. Your chat online is constantly busy. How can she sort this?

  • ITgeekess Ess (@ITgeekess) reported

    @O2 Hey @O2 - could you advise re. The above pls. Will thr S21 fe ever be compatible with WiFi calling? See. To have 1 bar (if that) of signal) inside the house.

  • MattWheeler89 Matt (@MattWheeler89) reported

    @O2 When you’re 72 hours into @O2 ‘s promise of a 24 hour call back and o2 think a few meaningless and dead end DMs will help the issue. @TheFCA next…

  • bombebsky Bombebsky (@bombebsky) reported

    @O2 @O2 really disappointed at the complete lack of support in dealing with your error! Still completely without a phone!!

  • turnbullbutler Beth Lindsay (@turnbullbutler) reported

    @O2 still no signal in Brighton What is happening? Please don’t refer me to website with how to fix this? I need to be able to use my phone and data I’ve paid for and not see again that your mast is having problems for over 24 hrs

  • McGill182 Jonny Hammerstein (@McGill182) reported

    @O2,Morning there, is there an issue with the Greggs coffee voucher on the Priority app this morning? It says it is no longer available but we are within the promo dates and it is after 7am.
