O2 Issues Reports Near Chelmsford, England

Latest outage, problems and issue reports in Chelmsford and nearby locations:

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • KevinRowley4 Kevin Rowley (@KevinRowley4) reported from Maldon, England

    @O2 for weeks now, Maldon CM96JR no 4 or 5G signal, voice calls virtually impossible at times. What's going on? Thank you

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • LairdDourka Andrew Dourka-Laird (@LairdDourka) reported from London, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • IanMaxy94 Ian Maxwell (@IanMaxy94) reported from Billericay, England

    Is transferring of SIM cards supposed to give me no service on both my old and new phone @O2??

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • 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.

  • 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?

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

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

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

  • StaceyFriend16 Stacey Friend (@StaceyFriend16) reported

    @O2 such disappointing customer service this evening! I have been a customer for 13 years and now looking to move as a result.

  • Mezin1905 Mezin Aslan (@Mezin1905) reported

    We paying a lot to @O2 but the data service is absolutely S**t.... when I call the #O2 technical service l, they say "we have a technical issues sorry that"

  • cajjio Carol Johns_TC (@cajjio) reported

    @O2 when are you going to sort out your signal issues in my area, I am losing business as my clients cannot reach me. This has been going on for 6 months, keep getting fobbed off! Paying for a service that myself and thousands of others not getting.

  • TomKBowman Tom Bowman (@TomKBowman) reported

    @res_pubblica @RevRichardColes Which doesn’t suggest @O2 have their focus on customer experience. If it worked people would use it!

  • family_jules Jules Gray (@family_jules) reported

    @O2 I don't know a Barbara. And I'm afraid I deleted the texts. I got one about changing my online password. I haven't done this. I got another calling me Barbara which appeared to be a customer service follow-up call.

  • KinkMonstrous Scott Kendrick (@KinkMonstrous) reported

    ok so my phone broke last tuesday, a week ago and I got in touch with @O2 on wednesday to get it picked up, they never arranged someone to pick it up so they said they would get someone to pick it up the day after and then again no one picked it up, they finally picked it up /1

  • KinkMonstrous Scott Kendrick (@KinkMonstrous) reported

    nearly a week after i reported my broken phone, they said it would take 48 hours and while it only got picked up yesterdat i went and did research on how long it takes @O2 to take a claim seriously. Some people on twitter has said that it takes or could take up to /2

  • browned81 edmund (@browned81) reported

    @O2 trying to swap my old number from another network to my new account with o2. Doesn't appear to have worked, can't get through on the phone and the my o2 app doesn't help

  • mattmartincouk Matt (@mattmartincouk) reported

    @o2 What is going on with your network at S74 0PB. Multiple devices have full signal on 4G getting sub 1Mb down and up is so poor I can't even test. Vodafone and EE at the same location (full signal too), 50Mb+!

  • StaceyxGraves Stacey (@StaceyxGraves) reported

    I wonder if @O2 are going to compensate for the fact that I havent had any signal at all for 2 days. Not even one bar. Getting stupid now
