  • IanPike https://techhub.social/@ianpike 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@IanPike) reported from London, England

    @O2 Network reset? Not sure what that is... Not in London often and last two times when I try to connect to wifi extra it requires login info, multiple locations across the tube network. I've searched for a solution and doesn't seem to be any options.

  • juliet_gough Juliet MacKenzie Gough (@juliet_gough) reported from London, England

    @O2 can I use my phone in Israel? I’m pay monthly customer.

  • Shaneyfirkins96 Shane (@Shaneyfirkins96) reported from London, England

    Is anyone else having issues accessing @O2 Priority Mobile App on the S23 Ultra... i haven't been able to access it since the s23 Phone's have Been Released

  • JulianLittle4Ag Julian Little (@JulianLittle4Ag) reported from Little Dunmow, England

    Apologies to anyone who has tried to call me at the back end of this week. Badly let down by the useless service @O2 who are now saying that it will take ANOTHER 3 working days to move my number 🤬.

  • SimonHemmingshj Simon Hemmings (@SimonHemmingshj) reported from Chelmsford, England

    @O2 @GarethTurpin I appreciate your personal message. However, I now remember why I left you last time, lower than average service, and now a 17.3% total price increase, which is disproportionate and completely knobbish if you ask me. @BBCNews

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I tried a browser but priority it kept saying I wasn't logged in. It never worked

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

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • KevinRowley4 Kevin Rowley (@KevinRowley4) reported from Maldon, England

    @O2 for weeks now, Maldon CM96JR no 4 or 5G signal, voice calls virtually impossible at times. What's going on? Thank you

  • 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.

  • 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

  • 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.

  • 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.

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

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • 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...

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

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

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

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

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

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • 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

  • CarlPuttnam utterly_genuine_Carl _Puttnam (@CarlPuttnam) reported

    @grok would it be true to say that the UK's worst phone and internet companies are @virginmedia and @O2 ?

  • CarlPuttnam utterly_genuine_Carl _Puttnam (@CarlPuttnam) reported

    @grok Are @virginmedia and @O2 the UK's worst supplier of phone and internet?

  • Stellasessions Stellasessions (@Stellasessions) reported

    @O2 Why is the reception so poor between Luton and London on the @TLRailUK??? I’ve had better 5G reception in Northern Thailand at an Elephant sanctuary in the Jungle!

  • Kentishred Brett (@Kentishred) reported

    @o2 still no signal through the whole high street at Tonbridge. Been months now - is it ever going to be fixed?

  • RachT234 RachT234 (@RachT234) reported

    Even accessible tickets were screwed on @axs_uk, @TheO2 (only one I was following, but I know it was generally bad) . heartbroken, Lewis is the only artist i've wanted tgo see in years. I don't have any hope for Thursday, feels like they are all gone. @o2 "priority" itself was a farce as well

  • hen_ren16 Essential Parenting (@hen_ren16) reported

    @MattsFarming @O2 I am sorry to hear about your mother's death and the problems you have had with O2 O2 is in my top 3 companies for the worst customer service I have ever had The other two companies are one of the debt collection companies which they employ (Moorcroft) and their partners Virgin.

  • shmooza bobbyb (@shmooza) reported

    @O2 the worst service. E sims dubs work. Got told to go to a store and pick up a SIM card. No one said I needed id other than my phone. Now they won’t serve me. A week sorting so far

  • Itsmehiii_27 Itsmehiii_27 ✨ (@Itsmehiii_27) reported

    @O2 having such a bad experience with a new contract. Ported num to o2 3.5 weeks ago and every call showing as no caller ID. Customer service are clueless and just keep telling me to reset settings and it’s a phone issue but the same thing happens when sim is put in a diff phone
