  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • 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?

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

    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

  • 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!

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need me.

  • 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

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    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

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. Help!

  • pau1okey ᴘᴀᴜʟ ᴏᴋᴇʏ (@pau1okey) reported

    @deanwmedia @O2 It's sim related. I can't even cancel it now. I've gone past annoyed, I'm entering disappointed territory.

  • bwlshanh Losing My Religion (@bwlshanh) reported

    @NadineDorries @virginmedia @O2 Wow. So, so stupid...

  • tobybrxl Toby #FBPE (@tobybrxl) reported

    @NadineDorries @virginmedia @O2 Damn you're unintelligent. How can you possibly be an MP?

  • KreissignalSh3 𝕂𝕣𝕖𝕚𝕤𝕤𝕚𝕘𝕟𝕒𝕝 (@KreissignalSh3) reported

    @NadineDorries @virginmedia @O2 Hang on. You wanted the EU to force British mobile-phone companies not to pass on the costs of EU roaming to British customers? How exactly was that supposed to work, and which court would have jurisdiction in the event of dispute?

  • s21sjm Sarah-Jane Shaw (@s21sjm) reported

    @O2 I have recently signed up to one of your Volt tariffs after leaving EE. For some reason the Volt options do not show on my account how do I resolve this problem

  • dean_mackintosh Dean Mackintosh (@dean_mackintosh) reported

    @O2 No point.. I already dropped you a DM and still nothing done. I can’t believe a company the size of o2 that you don’t take a security breach very serious? Because your customer service department keep lying to me on a regular basis.

  • EuropeanEnglish Angela 💙 Wear a Mask 🇪🇺🇬🇧🇮🇪🇫🇷 #JohnsonOut (@EuropeanEnglish) reported

    @NadineDorries @virginmedia @O2 Oh, Nadine. Your lies can be found out. Then you'll look even more stupid (if possible).

  • NathanR33900744 Nathan attempting to understand both sides. (@NathanR33900744) reported

    @BorisJohnson @virginmedia @O2 I'd welcome a decision on what this poor excuse for a government is doing about the growing cost of living crisis. More tax, more bills and less public service. Still at least all you poor MPs can now have £2200 pay raise. Cost of living crisis just for everyone else it seems

  • AlanDeAsha1 Dr. Alan De Asha (@AlanDeAsha1) reported

    @NadineDorries @virginmedia @O2 You, my corrupt Tory friend, appear to be stupid too… a heady cocktail

  • davegilsenan Dave Gilsenan (@davegilsenan) reported

    @O2 It's not a change of mind. You don't provide a basic service allowing me to make calls and send texts. I don't live somewhere remote but there is no signal. Not having texts over wifi is a really poor service
