    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • 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

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • 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?

  • 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

  • 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?

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

    @O2 your customer service is an absolute joke.

  • 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.

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

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

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • 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

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

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

  • 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...

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

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • 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!

  • 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.

  • SaraB72425653 SaraB (@SaraB72425653) reported

    @O2 I have had no phone signal for 2 days and cannot get into the My02 app as the verification code is not accepted everytime. Can anyone help please.

  • TimJBurden Tim Burden (@TimJBurden) reported

    @O2 Hi, can someone please sort my service issues out as a matter of urgency. I can’t receive phone calls and have no voicemail access anymore. Any online guru or call centre help has failed for nearly 3 weeks now. Please direct message me ASAP. Thanks.

  • gsw1396 Gordon Walker (@gsw1396) reported

    @O2 just upgraded my phone but when I try to login to myo2 the SMS verification code doesn't work. Tried many times. Can you help?

  • PaulaMaria84 Paula Maria (@PaulaMaria84) reported

    @O2 Haven’t been able to make calls for the last two days due to a mast being down. No information sent at all- had to look it up on your website to find out what was going on. Presuming we’ll be getting money off our bill for not even being able to use our phones??

  • vickerspd Paul Vickers (@vickerspd) reported

    Anyone else on Teesside having issues with @O2 signal?

  • ShannonLucyyy shannon (@ShannonLucyyy) reported

    @O2 help me pls

  • UnicornRunning Paul Jukes (@UnicornRunning) reported

    @O2 Fair enough, looks like I missed that when taking it the offer as it is quite buried in the Ts and Cs and not exactly phrased too well. Pushing out the six month free offer at the same time as the £2 discount didn't exactly help. I won't be the only one caught by this.

  • MiltonFee fiona m (@MiltonFee) reported

    @O2 good evening. Hubby trying to cancel with 02 as has now changed to tesco. Checked with 02 and clicked on contact Us- takes him on a never ending click click here to cancel ... Click here to cancel... Round and round in the same circle 😶 any ideas?

  • I_am_Pablo78 PabloRydoski (@I_am_Pablo78) reported

    How the hell can a phone network be so poor? Again sat in work and getting 0.4mb on 4g @O2 Best bit? Colleagues around me on @VodafoneUK are getting around 55mb. Both using the same shared mast. And again - out in Liverpool centre - 1.3mb. @o2 Action? - fobbed off again.

  • MiraTara4 MiraTara (@MiraTara4) reported

    @O2 I’m so unimpressed that if I ever get connected again or god forbid actually get to speak to an agent I will be switching phone providers. What is the point of paying if I don’t get service!!
