    @O2 I've replied however this is a know issue with these receivers where network operators reduce the speeds. I get 30mb on my phone and 0.5mb on the large dish. This makes no sense

  • beckywatson123 Becky Watson (@beckywatson123) reported

    @O2 guys need some help! Just took out volt yesterday and my mobile number is moving over from virgin, but I have a sim that has arrived today from you, but when will the number transfer what do I need to do? Help! Thanks

  • Louhawke1994 Lou Hawke ✌ (@Louhawke1994) reported

    @O2 I've tried that. But even in places I normally get 5G, still nothing? Just says emergency calls only

  • ellie_dragon Elaine Harding (@ellie_dragon) reported

    So DPD failed to deliver daughters new phone stating no one was in - attempted delivery wrong day & didn’t leave a card yet O2 have still not responded despite them “looking into it” on Monday & a complaint sent Tuesday. What’s the problem @O2?

  • MartynBowler Martyn Bowler 🇪🇺 #FBPE (@MartynBowler) reported

    @O2 really having problems with mobile signal for last 24 hours or so. According to your website your upgrades could take until 27/01. I’m working from home & need a decent mobile signal. Help! #Mobile #mobilesignal #workingfromhome

  • Noonah2 Nikki Dyer-Scott (@Noonah2) reported

    @O2 I have NEVER received such horrendous customer service. Taking £240 out of my account and then saying you can't refund my money. Diabolical. Going back on your word and leaving me with no phone. THE WORST COMPANY. DO NOT BECOME AN O2 CUSTOMER. #o2 #NeverAgain

  • SeriousShortbrd Davies Tom (@SeriousShortbrd) reported

    Hi @O2. I don't seem to have access to the Disney Plus free period on my account. I am a new pay monthly account, and have never redeemed Disney Plus with you previously. Who can I contact to resolve this?

  • mizpah68 Jacqui Langstead (@mizpah68) reported

    @O2 I’ve just signed contract online and waiting for my sim to arrive. My concern is my PAC code expires on 26/01/2022 and then I will have to cancel the new O2 sim and start the process again. How long for sim to arrive

    @SonyElectronics @Android @O2 Android 12 update forced on me has now corrupted my phone with no way to roll the system back. What are you doing to rectify this? I need my phone for work. Don't release updates if they're not fully tested! #android12crashing #sonyxperia1iii #help

    @O2 Disgraceful treatment no one knows what they are saying. This is the most appalling service ever I’m aghast at the inefficiency
