    Poor network in Se6 @O2

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Hounslow, England

    @O2 Phone masts are down at my work and home so not good.

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow please

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.
