  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Marc_Hadley Baron Mazzashow 💙 (@Marc_Hadley) reported

    @getnorthern @O2 Funny how communications companies are the worst communicators isn't it?

  • Andy_TheGrouch Andy (@Andy_TheGrouch) reported from Bryn, England

    @O2 no chance i’m renewing, genuinely shite network coverage, cant make call when driving without it sounding like someone is under water & call failing. Mast been down in Ashton for over a week. Phone basically useless. Troubleshooting links are pointless - not good enough.

  • TamlynWorrall Tamlyn Worrall (@TamlynWorrall) reported

    @O2 not only did you fail to transfer my sons number to his new account, in spite of hours on phone & assurances today, it seems you have now CUT OFF both phones completely. And yet, we are being charged for 2 accounts with O2. Neither phone number works. Please call me urgently.

  • ihhi987 IH (@ihhi987) reported

    @O2 It says you’re doing upgrade work. You haven’t answered the question about a discount. Unacceptable to not have service all week

  • Robbo3105 Kay Robson (@Robbo3105) reported

    @O2 Can you advise if there are network coverage issues at the Creamfields venue? No signal available whatsoever for a family member. Trying to understand if there is a fault and if it will be rectified. Thanks!

  • notdodgy Roger Leitch (@notdodgy) reported from Solihull, England

    @O2 Getting very close to the point of cancelling my order. The port has failed and I have no service. Cannot get through to your support as there are no agents available. No reply to FB message since 9 am. The clock is ticking...

  • D_RKirkpatrick Dale Kirkpatrick (@D_RKirkpatrick) reported

    @ConnaireMcG @O2 If you turn on "WiFi Calling" then assuming your WiFi is decent, then it shouldn't be a problem. That's how I got round always flipping to O2 Ireland down in the Point

  • jamcc86 Jam (@jamcc86) reported

    @O2 Hi I am on Virgin Mobile. I’m in Spain at the moment and have no roaming despite roaming being on. I’m finding it very very difficult to contact Virgin Mobile. Please help!!

  • Link2076 LinkoVitch (@Link2076) reported

    How come I get messages from @O2 telling me there is work in my area to improve service, and now I get a text from them telling me using WiFi for calls may be better quality... So pay for a service but don't use it is the message I guess?

  • getnorthern getnorthern - “a discrace to Britain” - “*******” (@getnorthern) reported

    @Marc_Hadley @O2 Awful service with regards to this. Generally happy with them, but not happy with being fobbed off.
