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!!

  • 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.

  • 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

  • 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!!

  • 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

  • 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.

  • 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.

  • 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

  • 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 🤬.

  • 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

    @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!!

  • 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.

  • 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

  • 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

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

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

  • 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?

    @O2 I have no more time to waste on this and you have my money which is terrible customer service. Please advise me on an email address?

  • arpita07_dutta Arpita Dutta (@arpita07_dutta) reported

    @O2 This is the 4th week in a queue I get this error and I am unable to get my movie tickets. I had raised a request for this issue but no help. I think it’s time to quit the O2. #O2 #freemovie

  • tay100922 (@tay100922) reported

    @O2 hi can you please tell me why I’m paying £80 a month when I can’t even use my phone without internet?? My phone never loads properly and videos constantly buffer

  • PaulPugsley Paul Pugsley (@PaulPugsley) reported

    @O2 obviously by the lack of response to my earlier tweet @o2 are not very good at customer service mores the point don’t even care.

  • JoeSturman Jody Sturman (@JoeSturman) reported

    I've spoken with @virginmedia who said I need to deal with @o2 to fix their mistake. O2 get confused when I tell them that the email they have for security purposes is not mine. The are also confused that I don't have the sim that I agreed to, as it hasn't arrived. 2/3

  • jibbajabbasteve Steve N (@jibbajabbasteve) reported

    @itspaulactually @O2 no this is more signal drops and distorted calls and just generally poor. And when you check various masts where these are been used masts just say they are been worked on. For example, 2 masts in Thorne, Doncaster, both show the same

  • BradClarke1996 Brad Clarke (@BradClarke1996) reported

    @O2 really need your help here. Out of the country so it’s really hard to get hold of you. Can you sort me out on here, it’s been an absolute nightmare trying to get anything done through your app

  • JohnAnd57093594 John Andrews (@JohnAnd57093594) reported

    @EnglandRugby @O2 Another horrid thing from @UmbroUK. Saved so much money on Bris and Enfland kit the last season or so.

  • cbc_75 Charlie Cochrane (@cbc_75) reported

    @O2 @hughjahfink Moved over to O2 a couple years ago… contract ends in 2 wks - the data coverage & speed (SE & London) has been utter garbage from day one by comparison to all other providers I’ve used. Never again using O2!!

  • tedsanders53 Ted Sanders (@tedsanders53) reported

    @bryony_xxx @O2 @GreggsOfficial Greggs and O2 either don’t want to make this issue public or don’t know what the problem is. Something is wrong with the scanners in Greggs which is preventing them being able to accept the o2 codes (presumably they are refusing to type the codes in). Perhaps try being honest??
