O2 Issues Reports Near Great Dunmow, England

Latest outage, problems and issue reports in Great Dunmow and nearby locations:

  • 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?

  • 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

  • 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

  • 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

  • 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.

  • 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

  • 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?

  • 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!!

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

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

  • 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!!

  • 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

  • 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?

  • 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.

  • 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.

  • alicoults Alison Coulton (@alicoults) reported

    @O2 That’s Just terrible, I’ve constantly been trying to get on the app without success since 09:45 with the odd glimmer of hope until this afternoon till now it says it’s actually down so how can you be sold out ? I think a fuller explanation is needed to your loyal customers!

  • ClaireIreland73 Claire (@ClaireIreland73) reported

    @O2 Got mine and feeling very lucky as i know so many people had problems

  • gingerbloke53 David Robson (@gingerbloke53) reported

    @O2 @virginmedia no idea how you managed to sell out when the priority site has been down for over 13 hours… Guess the staff all have them on the resale site - absolutely shocking one very disappointed o2 and virgin customer!!!

  • poultonbrown Lisa 💫🐘🐕‍🦺 (@poultonbrown) reported

    @EdieBeth @O2 App down , website down, complete 💩 show. Glad I’m not a paying 02 priority customer (my work phone is 02!)

  • spartacus_bets Rocket_Man Inplay (@spartacus_bets) reported

    @O2 @phillipc26 They will be able to take payment pal, that’s the only thing they’re good at! Can’t provide a decent service to customers tho! Absolute disgrace today, how can you be a premium network provider but website doesn’t work?

  • HHvirtualPA Virginia Davis🌸 (@HHvirtualPA) reported

    @O2 Your app has been down all day even before the tickets went on sale. How have you managed to sell out? #O2Priority you are joke especially when sold tickets are selling for astronomical prices. Who have to sold to? Not your customers.

  • ladybirdavfc sarah bird (@ladybirdavfc) reported

    @O2 At 4pm your customer services team confirmed over the phone that the app and website had crashed at 10am and there was no update as to when it would be restored- but to keep trying. Please explain O2!!!!

  • BELINDA08 Belinda (@BELINDA08) reported

    @O2 Who have they sold them to when your app has been down all day and is still down now 14 hours later 🤬 you should of been prepared that it was going to be high demand !!!

  • CanavanPhilip Philip Canavan (@CanavanPhilip) reported

    @O2 How exactly have all the tickets sold out and no one can access the app to purchase tickets!? Very disappointed with a service that completely fails the main objective of its delivery!!

  • GAVRS83 GavR (@GAVRS83) reported

    @andyw83 @ChrisBurgess72 @O2 Yes-appears they've taken it proper down now, overnight I suspect... Go through web browser not app, as above, ignore when you when you enter code & says a problem, there isn't-always tells me that, click to tickets... Not helpful for you in pool but London 02 seem easier to get.
