  • 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 🤬.

  • chris_rugs Chris Ruggles (@chris_rugs) reported from Great Yeldham, England

    Hi @O2, just a heads up...me and thousands of others will leave your network if you advertise on GB news. Have a long hard think about what you will be funding. #DontFundGBNews

  • paulhayward200 Paul (@paulhayward200) reported from Wendens Ambo, England

    @O2 Took out a new IPhone contract back in November. No problems paying but I wanted to add a Apple Watch on the account. O2 keep on cancelling the order even though I pass the credit check.

  • hadhamlane Andy Lane (@hadhamlane) reported from Bishop's Stortford, England

    @O2 ...and then when you’re signed up they change your deal to make you worse off. #O2 reducing the friends & family discount for a loyal customer is the last straw for me.. #O2

  • 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.

  • 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

  • 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.

  • Uptowndiscos Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England

    @techdotintel @virginmedia @O2 I'm currently a Virgin media customer and business O2 customer. Do I qualify?

  • 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?

  • 1011FOXEE beverley fox (@1011FOXEE) reported from Takeley, England

    @O2 I am trying to apply the discount I get for working at Tesco,it won’t let me use my email as used for my daughters account,help!!

  • MissClaireW CLAIRE WALMSLEY (@MissClaireW) reported from Halstead, England

    @O2 any resolution to your app not working, logins just go back to the same email verification page? So many people posting & no answers?

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

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

  • Uptowndiscos Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England

    @techdotintel @virginmedia @O2 I'm a virgin HOME customer and an O2 business customer but I don't qualify

  • LongshanksE10 Richard Astley (@LongshanksE10) reported from Bishop's Stortford, England

    @o2 I ,along with seemingly many others, wish to know why your 4G has been virtually useless over the last week or so please, or better yet, when the service will improve, but you don’t seem to be replying to anyone. Please help.

  • Uptowndiscos Uptown entertainment discos (@Uptowndiscos) reported from Harlow, England

    @O2 the answer to that question is primarily no. I would have to leave Virgin as a HOME customer and then sign up as a business customer? What about my TV package?

  • AbbeygaleRose 𝐀𝐛𝐛𝐞𝐲𝐠𝐚𝐥𝐞 (@AbbeygaleRose) reported from Chelmsford, England

    Beginning to regret renewing my contract with O2, their coverage in Chelmsford is awful. My 4G works about 20% of the time. @O2

  • leon_dave_smith Leon Smith🇬🇧🇪🇺❄️ (@leon_dave_smith) reported from Harlow, England

    @tescomobile @O2 any coverage issues in CM20, been terrible yesterday and today, signal 4G keeps dropping out

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @O2 Sounds easy doesn’t it!! Every call is from a different number, it wears me down, in excess of 20 yesterday all blocked & inadvertently called a couple back in error trying to block late at night with brain fog. So cross!!

  • j4cobwood Jacob Wood (@j4cobwood) reported from Harlow, England

    @O2 I need support with my network, I’ve tried everything that the website says, my calls won’t connect and when they do the sound is cracking and poor. Most of people trying to call me can never get through either. This has been happening for months now

  • jill_jtc Jill T food safety (@jill_jtc) reported from Sawbridgeworth, England

    @GlassBeadsLotti @O2 Thanks - trouble is it’s not a fault with the phone; service providers have got to up theirs game to stop this happening!!

  • Mxdir Mxdir (@Mxdir) reported

    @O2 hi team - I'm having issues with an international caller being sent straight to voicemail - i.e, i don't even get a missed call from them, any ideas?

  • woollala11 woollala1 (@woollala11) reported

    @O2 how hard is it to do transfer of ownership. My ex and I have spoken to two customer service and gave two passwords and yet someone still mucks up. It’s getting ridiculous that Ive to keep calling with my ex (going through a breakup which isn’t easy) and causing me more pain

  • denise_AOL Denise Robinson (@denise_AOL) reported

    @O2 as an O2 Business customer 4yrs+ was shocked to discover that you still can’t connect an Apple Watch with eSim “isn’t currently compatible with our Business Platforms”… How long is this going to take you to catch up with the competition?? #Vodafone sorted in 2020 @Apple

  • justicefingers RAYZ (@justicefingers) reported

    Just a few things I enjoy more than trying to go on the internet using @O2 mobile network. 1- Banging my head against a wall. 2- Stepping on Lego. 3- Toothache. 4- Listening to commercial radio. 5- Getting a paper cut. 6- Visiting the 02 shop where they just blame your device.

  • BerryandEmmett Berry (@BerryandEmmett) reported

    @O2 No problem! Can I just check, am I okay to keep using my phone until it loses signal or should I not be using it?

  • cromeaticc mtv 🐑 (@cromeaticc) reported

    It actually says, Statute,. No matter the debt amount, leave people with an emergency line @3 @o2

  • Fitzy__07 Fitzy (@Fitzy__07) reported

    Has anyone sent a phone through @O2 O2 Reycle and used a courier service? I tried to sell a phone before and the post office lost it, so thought it made more sense to send via a courier like DHL

  • MillieFiore 🐀🌻🌻🌻😷💖 Millie Fiore 🌺🐄🕷️🌳 (@MillieFiore) reported

    @O2 Was down to 3G, again. Now buffering at 4G. It isn’t the building; it can work quickly: it just isn’t.

  • MrsE29 Wendy (@MrsE29) reported

    @O2 You having a laugh! Been trying to get working service since I moved from vodaphone last February…worst thing I ever done.

  • Butts1977 77SPB (@Butts1977) reported

    @O2 Unless you can sort my signal out I'll be saying 👋 Reported it time and time again, no updates, no improvements. DM waiting for you but no reposnse.
