  • 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

  • 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

  • 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!!

  • 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?

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

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

  • 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

  • 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.

  • 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?

  • 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.

  • 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.

  • 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?

  • 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

  • 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.

  • 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?

  • 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

  • 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 🤬.

  • 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

  • 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!!

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • 3imear Eimear McGovern (@3imear) reported

    @O2 received 4 calls and a text today telling me I hadn't paid my direct debit and would be charged £3.50 - even though you took my payment and then refunded it. Shocking to penalise customers for your mistake when the customer service agent admitted it was a widespread problem.

  • MsOB30 Carla O'Brien (@MsOB30) reported

    @O2 I want to set a spend cap on my account but the website is down and I can't contact anyone to do this, not very helpful.

  • hordak2569 Hordak2569 (@hordak2569) reported

    @O2 hi I need help with the o2 priority cinema codes I have sent a direct message thanks

  • glenaowen Glen Owen (@glenaowen) reported from Chester, England

    99% no @O2 signal in and around Chester, been in store today to swap SIM to try and fix it but still no better. 😩. Anyone else experiencing the same?

  • alan_wain alanone (@alan_wain) reported

    Hey @SamsungUK and @O2 STILL no phone wtf is going on ????

  • CurryInTurry DJ Nerja 🇺🇦 (@CurryInTurry) reported from Manchester, England

    @O2 @purpledolphins7 They didn't help me. They didn't apply the increase in speed. In fact they said I could have 1gig for £30 extraper month. False advertising and liars!

  • _dopie_ Dopie (@_dopie_) reported

    @iiloloi @LoveIsland @O2 This gotta be one of the worst things I’ve seen hahhha

  • Tow_Tales Towcester Mole (@Tow_Tales) reported

    @O2 when are you going to fix the signal strength in Towcester? #3g #towcester

  • Aa_l_e_x_______ alex (@Aa_l_e_x_______) reported

    @O2 phone upgrade…phone lost by @DHLParcelUK …none of the companies know where my new phone is… they send me from one to another!two massive companies that cannot locate a phone…and the customer has to just wait for them to blame each other!!! Disgusting

  • lukew492 Luke Watkins (@lukew492) reported

    . @O2 Intermittent in my area for 5 weeks now due to a broken mast. Waited for a call back from a manager twice now to no avail (likely as I have no signal, as I’m on O2). Anything you can do to help? Going round in circles with your phone support.
