  • 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

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

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

  • 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?

  • 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.

  • 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.

  • 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

  • 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.

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

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

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

  • 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.

  • 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 👌🏻

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

    Poor network in Se6 @O2

  • 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.

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

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

    @O2 your customer service is an absolute joke.

    @O2 I’ve never used this code before

  • KNMNoble Noble (@KNMNoble) reported

    @O2 is there a country wide outage right now? I cannot seem to use data anywhere I go, along with that I also have no signal too, and it’s been like this all day

  • Furbz_85 Adam (@Furbz_85) reported

    @elizabethAVFC @O2 It's dreadful isn't it. No matter where you are it sucks. Even after doing all the O2 tips (which are common sense stuff really) it doesn't improve. How can a whole town the size of Blackpool have such bad coverage.

  • D5S80 S80 JGO D5 (@D5S80) reported

    @O2 TO MY 60 YEAR OLD FATHER WHEN HE AND MYSELF ARE BOTH OWED SUBSTANIAL AMOUNTS OF MONEY FROM O2. A GIRL CALLED ISHMA FROM THE CUSTOMER SERVICE DEPARTMENT TERMINATED MY CALL WHEN SHE DIDNT HAVE A RESPONSE OR JUST COULDNT BE BOTHERED TO SOLVE MY COMPLAINT ALSO REFUSED....

  • Londonscotty Scott (@Londonscotty) reported

    @O2 being charged premium rates for texts from 87121 - no idea who they are or how to stop it! Help, please! Can you block them?

  • Roebot6 Roebot (@Roebot6) reported

    @O2 Done this a million times. Makes no difference. I have to travel about half a mile down the road fir any signal to return

  • itsemma_reilly Emma Reilly (@itsemma_reilly) reported

    @O2 I spoke to someone, who said I’d have to pay 2 months to change the date 3 days. So **** that irl just pay it another way. Absolute bullshit

  • Turbobuddah Sean humphries (@Turbobuddah) reported

    @O2 No point, we know exactly what it is and it's not a network error or anything you can generically point to off a screen. You removed towers and your network now can't support a small town, you've gone from being one on the better networks to unsable alot of the day

  • leeinengland Lee B (@leeinengland) reported

    How do I get @O2 to stop texting me. I pay you for the phone and the plan. I don’t want your crap via SMS or email or any other medium. Stop ****ing texting me!!

  • twillisc Tom Willis (@twillisc) reported

    @O2 I’ve already seen this. I’m convinced it’s an issue with my account as my device performs well when testing with other networks a
