    @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

    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

  • 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.

  • 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?

  • 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.

  • 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!

  • 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

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

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

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

    Poor network in Se6 @O2

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • 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.

  • 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...

  • 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?

  • 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.

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

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

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @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

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

    @O2 your customer service is an absolute joke.

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

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • Lava087 Simon (@Lava087) reported

    Since I've had a 5G SIM, my 4G signal has been absolutely shocking! Where I live I rely on 4G! I don't know why you upgrade people to 5G SIM cards when they don't live in a 5G area!! 🤬 @O2

  • StephTimms01 Stephanie Timms (@StephTimms01) reported

    Am I the only ex @O2 customer not aware of their scam of withholding credit balances when you leave them? Once your account is closed you get a message saying a final bill has been generated. But you can’t view the bill online because you’re no longer a customer. 1/3

  • katannscott Katharine Scott (@katannscott) reported

    @O2 I’ve had a message pop up on my phone saying O2 has turned off 4G calls? How do I fix?

  • cbarton94 conor barton (@cbarton94) reported

    @O2 what happened to your customer services? Messaged today at 12:46 about an extremely slow data issue I am having, told you had issues with your system but would be kept updated. Now 18:10 and heard nothing. Been on hold for 26 minutes and no answer.....

  • johnsub40 John Sheridan (@johnsub40) reported

    @Dylanscall1 @O2 I was on whatsapp and twitter and couldn't even look at a video never mind download them. Pure shite.

  • GeorgeBeresfor5 George Beresford (@GeorgeBeresfor5) reported

    @O2 I recently took advantage of an audiable app as part of an o2 deal but when I use the link you sent me it tells me I've already activated it, I already have the app but there is no change 8n status in that can you help me please

  • donlesac Donlesac (@donlesac) reported

    Travelled up to London today and forgot how awful the service is for @O2 everywhere in the South West.

  • AscottEd Ed Ascott (@AscottEd) reported

    Hey @O2 how come I have ordered from you but haven't been able to speak or use the chat function on your website for 2 days? Aren't you a communications business?? Still waiting on product, no update, no way of contacting you. 👎Great customer service, for all the wrong reasons.

  • Jonmain69 Mainy (@Jonmain69) reported

    @StephenEvans75 @O2 Mine’s OK mate I did have an Apple 1035 error just now when I tried to change my voicemail greeting which is some sort of WiFi issue.

  • Mimie_13 Jemima Jane (@Mimie_13) reported

    @O2 Hi, if I was to cancel my Apple Watch cellular plan am I able to re start it again at any time by adding it back on?
