    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Great Leighs, England

    @O2 The fact it’s in 3 seperate locations, where my current projects are located, suggests it’s on your side. To use the excuse that there is too much traffic is also ridiculous as means you have over sold your network.

  • JamesSharp87 James Sharp (@JamesSharp87) reported from Witham, England

    Hello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • rfothergill Ricci Fothergill (@rfothergill) reported from Brentwood, England

    @O2 Nothing received. When was it sent? Last message I had from you was an auto responder on 24th July stating that you’d respond to my complaint within 5 days. Have had nothing since.

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • KJDalby Kate Dalby (@KJDalby) reported from Chelmsford, England

    @O2 urgent my new provider activated the PAC code provided by you. Their sim card does not work because apparently my device is locked with you. I cannot text you to get it unlocked. Please help asap.

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • RyanSchaverien Ryan_Schaverien (@RyanSchaverien) reported from Chelmsford, England

    @O2 Extremely slow data coverage for the past 3 weeks.... any help?

  • IanMaxy94 Ian Maxwell (@IanMaxy94) reported from Billericay, England

    Is transferring of SIM cards supposed to give me no service on both my old and new phone @O2??

  • 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.

  • 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...

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

    @o2 When will WiFi calling be available?? I live in an area where the call constantly drops, WiFi calling would be the solution

  • T0ny_Boy Tony (@T0ny_Boy) reported

    @O2 I'm currently in Greece and the roaming provider @COSMOTE supposed to provide connection. The only thing I receive is no signal or fake 4g without or with very limited speed. It is supposed that I'm paying my contract and I should offered the same functions as in the UK.

  • writesofway Peter Edwards (@writesofway) reported

    Who thinks £0.55 per minute is a reasonable mobile phone tariff? Add their Kafkaesque 'customer service' routine to the mix and what's not to hate about @O2?

  • HawanDs Hawan DE SOUZA VICENTE (@HawanDs) reported from Merton, England

    @O2 is okay but when it comes to speak to customer services 😴

  • ThomasEdmund71 Tom Richardson (@ThomasEdmund71) reported

    @O2 I was bemused by this text you sent me. Your signal has never come. I have never been able to text or phone on your network from my home “To improve your local network, we're carrying out essential work in ME194LZ. While we do, your signal might come and go”

  • MsCosmicCat Em (@MsCosmicCat) reported

    @O2 my o2 priority app isn't working. It says no network (even if on wifi), I tried clearing the data to log out and now it won't let me log in. The app is up to date

  • paul77thompson Paul Thompson (@paul77thompson) reported

    @O2 reception in Towcester has not got much better than the H+ network. Any improvements in the pipeline?

  • Ellwebb32 Ell w (@Ellwebb32) reported
