    @O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • 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.

    @O2 Hi could you help me please on my phone accounts I’ve always had staff discount since I’ve retired but it now seems not to be available anymore. I believe this was a part of my retirement package

  • JoeMartin73 JM (@JoeMartin73) reported

    @EnglandRugby @USARugby @O2 Poor Ted Hill still can’t get a start! Utterly ludicrous! What more does he have to do ? Seriously!

  • runtothrescue Run to the rescue with love (@runtothrescue) reported

    @O2 any update on the error 400 issue when trying to log in? I'm trying to upgrade but can't because I cant log in to check out

  • steveps83 steveps83 (@steveps83) reported

    I swear if your on @o2 and live in paddock wood Kent the re option is a bag of ****. I'd get better reception in Ukraine with the war going off.

  • Thurstan1982 Thurstan Wright (@Thurstan1982) reported

    @O2 Terrible stuff from O2 and DPD. Phone upgrade ordered. Phone delivered but only my wife in and she didn't have the PIN to accept the delivery. No redelivery the next day and phone sent back to O2 and new contract cancelled! Surely more flexibility needed around deliveries.

  • Woodsy2_0 Atlas woods (@Woodsy2_0) reported

    @O2 is absolute ******* shambles. cancelled my contract over 4 months ago and yet I still get random *** bills from you then better still you send me to debt collection. And now you've changed the login to virgin which I can even access cause I don't even have the sim. Ridiculous

  • LYCOICAT Mila (@LYCOICAT) reported

    @O2 I’ve paid online now but I’m absolutely livid still giving network issues 3 weeks on. I’ve not heard back from your “resolution” teams.

    Gerry @O2 Belfast. After being passed around the world - Philippines, India, South Africa - hours on calls since last Thursday with no-one making good on promises to fix the issue and return calls, finally problem solved! Deserves a bonus.
