    @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

  • IanPike https://techhub.social/@ianpike 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@IanPike) reported from London, England

    @O2 Network reset? Not sure what that is... Not in London often and last two times when I try to connect to wifi extra it requires login info, multiple locations across the tube network. I've searched for a solution and doesn't seem to be any options.

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • CatFankles Gem (@CatFankles) reported

    @O2 I've now had no service on either number for over two hours. I'm alone at home, don't have a landline and have no means of making the calls I need to make. This is the latest in a long line of F-ups since I made the unfortunate decision to join O2. Can you please help?!

  • Mr_Martinez75 Phil Martinez (@Mr_Martinez75) reported

    Now on Day 25 of @O2 (now part of @virginmedia ) failing to unlock my old phone for my teenage son to use. Twitter help was no help, customer service line gave false promises and emails have been ignored. Can't use a phone I have paid them for. How do I get them to do anything?

  • JoshuaMKite Joshua Kite (@JoshuaMKite) reported

    @neilvagg @O2 You know #tescomobile have a great reputation for customer service and are a virtual network running on O2...

  • rondon Ron Donaldson - Narrative Ecologist (@rondon) reported

    @O2 I have waited 2 days for switch of old number to new O2 SIM and now I am getting "SIM 1 not provisioned" error. I cannot now ring customer services and chat lines say not available. Can you help me please?

  • CatFankles Gem (@CatFankles) reported

    @O2 @BobPlumb7 Lol I love how you respond to this customer (I feel his pain, O2 is awful so far for me too) even though my message was sent much earlier. Still no response from you and I've still got no service...

  • JonRouse9 Jon Rouse (@JonRouse9) reported

    First time as an @O2 mobile customer. Fourth day with absolutely no mobile network coverage. Six phone calls so far. Are they usually this crap?

  • cam88x Cam (@cam88x) reported

    @O2 As many crew do, if I traveled to Barbados, Antigua, St Lucia, Jamaica - popular flights from the UK with thousands of crew per month, all of those would be subject to an extra £6 charge per day. Vodafone wouldn’t charge for that some plans. Your offering outside EU/USA is poor

  • ManLikeCourage #ShadeOfLife✨‼️ (@ManLikeCourage) reported

    @O2 u lot need to do better on your customer service how am I trying to pay what I owe you but you wanna keep me on hold for 40 minutes at this rate imma just leave your company

  • ian_foxall Ian Foxall (@ian_foxall) reported

    Hey @O2, how do I contact you by email/message? I keep going round in circles in your help section, and the chat function in my app tells me you’re busy!
