    @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.

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • paul_a_lewis Paul Lewis (@paul_a_lewis) reported from Barnet, England

    @O2 my wife joined O2 today and ordered a new phone however she provided you with the wrong email address, can you help change it? Thnx

  • 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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • 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

  • 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?

  • 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

  • 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...

  • 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

  • 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

  • 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

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • jamesy_c1 🍺 Crafty Jay 🍺 (@jamesy_c1) reported

    @O2 Why do I constantly loose 5G signal and recieve poor signal on NE3 Gosforth

  • BitnamSingh Bitnam Singh Khalsa (@BitnamSingh) reported

    @O2 Thanks for the generic response, however, the issue is beyond this. Someone from O2 needs to travel on a train from London to Peterborough, and maybe further north, to test the signal levels as I suspect the cell coverage is poor or not functioning correctly.

  • Leonara99550659 Leonara (@Leonara99550659) reported

    @AlStewartOBE @O2 Getting through to any company these days is a joke. Recorded messages about how busy they are and that they’re working from home still doesn’t help. I don’t call any more I email the ceo.

  • toni_g1986 Toni @evidenceUKhomes (@toni_g1986) reported

    @O2 It will cut calls. I know someone else is having issues too

  • Victoriamay1108 Victoria (@Victoriamay1108) reported

    @O2 @themichaelowen It would be nice if I actually get to use what I pay for monthly. Service is unusable, on a regular basis I can't make phone calls, send texts or use my data because of the woeful signal. At least once a month a mast by me is down. I'm sure though o2 will take out the full amount

  • Steph_HRhodes Steph (@Steph_HRhodes) reported from Grimethorpe, England

    @SamsungMobile I bought a watch yesterday from an @EE store. I was told I could connect to my @O2 phone via Bluetooth. However.... its its just not recognising my device. Its a Samsung s20 ... please help 😭😭😭 I was so excited now gutted!

  • GoodwinDavid David Goodwin (@GoodwinDavid) reported

    @O2 Hi, Porting from Vodafone to O2 yesterday. Lost service at 10am and since then nothing. No phone for almost 24 hours. Can you please help?!

  • mpj41 Herman the German (@mpj41) reported

    @O2 @Jimbo09001 Useless. My son has a business which relies on his phone. The network checker said on Tuesday it should be back to normal on Sat by 6pm. He cant even contact you as cannot receive or make texts or calls. If you cannot fulfill ur pt of the contract to supply a signal. COMPENSATION

  • Richyoscar1 Richard Jones (@Richyoscar1) reported

    @jimitar @O2 @themichaelowen Wow there is always one that instantly thinks of the worst and has no humour.

  • louiseomac louise (@louiseomac) reported

    @O2 got logged out of the app and now I can’t get back in keep being told I’ve been sent a code to my mobile number never had anything it’s been an hour now !
