    @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!

  • 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?

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

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

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

  • 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

  • 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

  • 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?

  • 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

  • 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..!

  • 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.

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

    @O2 your customer service is an absolute joke.

  • 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.

  • 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!

  • 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 👌🏻

  • 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

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

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

    @O2 Hi, I paid my bill this morning, there have been no service issues when I checked online, I've had signal all morning up until 30 minutes ago ... What's going on?

  • SMXshow Jammie Dodger - Reading Dune (@SMXshow) reported

    @O2 Of course. The number is +44 20 4552 1701 They say they’re calling from o2 and have all the information for me that was correct at the time when I was last your customer. It’s out of date now.

  • melaniejanehowe MJ (@melaniejanehowe) reported

    @O2 I’m abroad and have been cut off despite adding a bolt on for usage specifically for this trip. Cannot login as no codes are arriving via text message. Please can I get help urgently whilst I’m on wifi? Thanks

  • DomBoardman95 Dom Boardman (@DomBoardman95) reported

    @O2 is there going to be any form of improvement to the utterly **** signal you are providing across the country? Myself and plenty of piers/family members have had nothing but poor signal the past few months. Unacceptable from a company who regards themselves as ‘good’.

  • HelenNaylor26 Helen naylor (@HelenNaylor26) reported

    @O2 please let me know how to contact customer services for Priority. Thankyou

  • HelenNaylor26 Helen naylor (@HelenNaylor26) reported

    @O2 please put me in touch with customer services

  • GiveUpTheJosh Forty-Nine Sea Horses (@GiveUpTheJosh) reported

    @O2 I'm not having the issue, you are. Only reason I'm with o2 is for the free weekly cafe Nero drink, now it's being cut to one a month. Been holding out with o2 just because or this, because the service you offer in my city centre is atrocious. Says 4g but loads like 1G.

  • smackeroo Steve McElfatrick (@smackeroo) reported

    Awful and inconsistent customer service from @O2 - certainly not what you need at 5am abroad with problems to sort
