  • 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

  • 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

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

  • 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?

  • 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?

  • 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.

  • 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.

  • 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

  • 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?

  • 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

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

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

  • 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!!

  • 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

  • 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

    @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!!

  • 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!!

  • 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

  • tomtilly28 Adam Dack (@tomtilly28) reported from Harlow, England

    @O2 what are u doing my phone has just died logged in and all my service been disconnected why !!! Idiots

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • olimar99 Alistair Rattray (@olimar99) reported

    @ddphotograph @O2 I was with them for years and couldn't work out why I couldn't get signal whilst others could, even on same network. Switched to EE and now it's the other way around.

  • ddphotograph Dominic DEAN 📸 (@ddphotograph) reported

    So i have been with @O2 for over 30 years and the signal now is worse than ever. Recommendations please for mobile provider?

  • liammjwhite Liam White (@liammjwhite) reported

    @O2 you sent me an email saying i 'd get a free welcome gift (worth up to £89.99) if i downloaded the priority app. I've done so and am not getting anything relating to a free goft. Can you help advise what I need to do to claim my gift please 🙏

  • V_D_Onofrio Vincenzo D'Onofrio (@V_D_Onofrio) reported

    @O2 I have a business account. No voice or data service for 2 hours. Over the past month, your service has been increasingly unreliable. Is there any compensation for this? Can I terminate the contract early without penalties? #O2down

  • Clairejadex Claire Marsh (@Clairejadex) reported

    @O2 hi currently abroad and suddenly have no service ??

  • RachT234 RachT234 (@RachT234) reported

    I’ve since moved to @O2, who responded helpfully, respectfully, and actually listened — even when I had no service and had to rely on a family member’s phone (without Relay UK, and with encouragement). This outage was caused by Three failing to provide porting info, leaving me without service for around 10 hours. In contrast, Three left me feeling ignored.

  • dickieGT dickieGT 🐒🏳️‍🌈 (@dickieGT) reported

    Anyone tried calling @O2 recently? THE WORST EXPERIENCE EVER. #Wankers

  • AWKrey Andy (@AWKrey) reported

    @O2 what the hell is going on? Full 4G signal and can barely refresh my Twitter let alone watch the F1 qualifying.

  • Unofficial_Phil Phil (@Unofficial_Phil) reported

    @O2 ran out of data - didn’t receive a warning, couldn’t check my allowance. Had to spend £5 to connect to EE WiFi just to see my account. Awful service

  • therealsmorgan smo (@therealsmorgan) reported

    What is going on with O2????? No signal bars for days… No calls in or out! @O2
