    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?

  • 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

  • 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

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

  • 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 🤬.

  • 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!!

  • 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.

  • 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

  • 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.

  • 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

  • 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

  • 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.

  • 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!!

  • 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.

  • 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?

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

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

  • 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

  • ThisFireBurns__ AyyLiamaoo (@ThisFireBurns__) reported

    @O2 Now if only I could actually use my 4G in the UK instead of having it lock up due to the people with unlimited data hogging all of the bandwidth on tiktok, D+ and netflix. Giffgaff have no problems and yet use your service and they also offer EU roaming. £10 a month for 15GB also

  • Stuey3D Stuart Carr (@Stuey3D) reported

    @Kyidarmy @O2 Unfortunately for me EE are terrible around Milton Keynes where the wife works whereas o2 seems to be better. 3 don’t work where I live, the only one I’ve not looked at is Vodafone but last I checked they were expensive and also had crap coverage.

  • chell_wallace Chell wallace (@chell_wallace) reported

  • Victoriamay1108 Victoria (@Victoriamay1108) reported

  • nickybarrot84 Nicola Barrot (@nickybarrot84) reported

    @O2 WiFi calling doesn’t help me contact my kids’ schools or any other important calls. I’m paying for a service and not receiving it

  • AaronBrand86 Aaron Brand (@AaronBrand86) reported

    @O2 why is your signal and data strength so poor in the SS8 area now. It never used to be. It's ridiculous!!! If I'm not at home on my WiFi I'm missing so many calls and emails for work!!! #o2 #hadbettersignal10yearsago

  • JotaTheSlotta JotaTheSlotta (@JotaTheSlotta) reported

  • DiamondLights4 Diamond Lights (@DiamondLights4) reported

    @O2 Hi, I need to speak to someone with regard to trouble paying my bill this month. There was a number I rang but it was just a recorded message when I went through the options.

  • Kyidarmy Kyidarmy (@Kyidarmy) reported

    @Stuey3D @O2 O2 are terrible mate. Terrible customer service awful coverage. Can't wait til November to end my contract.

  • DOEZDOZENS The Goddard Empire (@DOEZDOZENS) reported

    @O2 HELP! On 8th July you declined my contract request, but took the the advance of £40. I no longer have access to my account but can’t reset my password either. I can’t speak with your team members because I’m forced to sign in to do so. How do I get my £40 back?
