    @O2 how come your service seems to be getting worse! 4G struggles with a video call and when it drops to 3G, which, once upon a time, was the standard, it literally means zero connectivity!! Unless of course my phone is being dodgy!

  • Cumberdanes John Haswell (@Cumberdanes) reported

    @O2 When I go underground on the Metro. I’ll see folk using their phone with no problem yet the second I go underground nada. Also York, as soon as I step off the train in York I struggle to get a signal.

  • Taylod61 ❌ David Taylor 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧❌ (@Taylod61) reported

    Once again @O2 4G network below 1Mbps or none at all. Bloody pathetic. Why can’t we have a network that has sufficient band width to Work. Or better still why don’t they get off the arses and roll out 5G? They don’t have a roll out program because you can’t find out about it.

  • darrenjg87 Darren Gregory (@darrenjg87) reported

    @O2 As an O2 customer I’d just like to have some in Central London

  • MrJordanSDean mash potato slander account - Jordan Stanhope Dean (@MrJordanSDean) reported

    @444molls For the second time this week, @O2 said they'd email me over some stuff to get my phone sent for repair, and failed to do so. I literally pay for insurance, and have to pay a hefty excess, and I get this SHOCKING service. It's taken all week so far. I'm a throw it at them soon.

    @O2 WHAT is going on with the signal today? In and out, being cut off all the time. #Devon

  • Place_of_Zen Place of Zen (@Place_of_Zen) reported

    @O2 what is the craic with your signal in Mid-Ulster? Why am I paying for this as it’s crap. Every single call I have made the past month has dropped, signal is never more than 1 bar. Total disgrace

  • oosaboos Susan Richardson (@oosaboos) reported

    @O2 hi. My son’s sim has stopped working. He is part of my account (friends and family) and I’ve checked both and both are registered and paid. Can you help please?

  • MartinG04413826 Martin Green (@MartinG04413826) reported

    @O2 Anywhere would be good with me! Your network is ****.

  • pauldevenish Paul 🏳️‍🌈🇬🇧🇸🇪 (@pauldevenish) reported

    Hi @O2 I have received a scam call from an O2 registered number, saying they are from @currys - can I flag this up with you both, as they are using your network to piggyback off a company they don't work for.
