  • 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

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

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

  • 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.

  • 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.

  • 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

  • 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?

  • 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!!

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

    @O2 Yeh you keep replying to people with this, & yet the link you sent either directs back to social media, or continues the issue of login problems... so... ?? @virginmedia @O2

  • 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!!

  • 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

    @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!!

  • 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

  • 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

  • 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

  • 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?

  • 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?

  • 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.

  • 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 🤬.

  • 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?

  • RachelMckechnie Rachel McKechnie (@RachelMckechnie) reported

    @O2 two days later and my number is not transferred over sooooo **** 😩

  • DebateMate1 DebateMate (@DebateMate1) reported

    @O2 how long can I expect to be without signal as my contract switches over? I was not informed I’d be without signal and was told it would be a straight forward switch

  • Gareth53178094 Gareth (@Gareth53178094) reported

    @O2 @virginmedia @ollymurs So O2 why do you ignore my DM’s to you for the poor treatment to your customers with PTSD. Really poor service

  • majadrobez7 Maja (@majadrobez7) reported

    @O2 my bill is overdue and i’ve been trying to pay for days now but my app keeps glitching and either telling me to try again later or simply not working. how else can i pay? (also please fix the app)

  • dhamer Dane Hamer (@dhamer) reported

    @O2 @o2businessuk I'm in the UK and my data network won't work😭 without network I can call customer services

  • SDCForeverMe SDC1 (@SDCForeverMe) reported

    @SkyHelpTeam I am extremely disappointed in both Sky and @O2. I have 3 contract I pay for and Im being passed about. Very very poor from both companies. I already spoke with Sky Mobile weeks ago, they reverted me to O2. O2 send me to Sky. No one fixing it

  • appccessible Kevin (@appccessible) reported

    Hey @O2 was your recent refresh promotion on the Sony Xperia 1 iv just a #scam? So many issues with O2 recycle not accepting listed devices showing 'not in portfolio' when checking the IMEI number! The recycle phone I have was bought by me from O2!

  • Silverflawsome simone stirling (@Silverflawsome) reported

    @O2 I can't try if Odeon completely disappears from the app! The fact that you aren't even mentioning contacting Tech support tells me you're well aware of this, and its likely done on purpose!

  • ChaLouMusic Louise Ellinson (@ChaLouMusic) reported

    @O2 I did try to redeem the code in the restaurant! It wouldn’t load - the wifi in @pizzahut was awful, the signal was intermittent, and when the browser did finally start loading other websites, the O2 one wasn’t working. How am I supposed to use it in those circumstances?
