  • 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

    @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

  • 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

  • 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

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

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

  • 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

  • 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

  • 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!

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

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

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

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

  • 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

  • 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?

  • 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

  • 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.

  • flynnbilton Flynn Bilton (@flynnbilton) reported

    @O2 need help redeeming voucher on from priority (Disney + for £2 less voucher) Thanks

  • DMcGwinn Daniel McGwinn (@DMcGwinn) reported

    @O2 Ordered a new SIM and customer services took a PAC code on ordering. Will it automatically move to the number we want (attached to PAC code) when sim is inserted / used? Still got a random number on it at the moment

  • emmtum emma tumelty (@emmtum) reported

    @O2 how are you meant to speak to a human. New phone still isnt working after 27 hours all it is is automated service live chat constantly busy no accessibility team for disabled people...help someone please!!!

  • Vanessabooty1 Vanessa Booty (@Vanessabooty1) reported

    @Greenwood18Lynn @O2 I’ve been with o2 for a long while but the service and cost is just not good now. May have to switch!

  • Hamzizi_786 Hamzah iqbal (@Hamzizi_786) reported

    @O2 hi I need help with redeeming my code it says it not correct when I try to Radeon Even though it is correct and it says that I need to select one if three options but they all don’t work e.g voucher meerkat movies or CEA need help as soon as possible 🥲

  • Ladyvittoria1 Victoria agostini (@Ladyvittoria1) reported

    @O2 Part 2. Not only that, your call handlers are stupid. Beyond stupid. I had to call of a landline from a carphone warehouse earlier because my phone couldn’t call out, I told them yet they still asked me was I calling from the number I needed to talk about. STUPID.

  • YogaSine Chala Atelier Yoga & Ayurveda (@YogaSine) reported

    @O2 is not providing a service! Explain how hot weather can affect the SIM card. What a joke! #London not receiving or making calls! The reason: unknown!

  • Aaron_Golightly Aaron Golightly 🏳️‍🌈 (@Aaron_Golightly) reported

    I haven’t even got a message welcoming me to the Network. Literally posting @o2 to use my own home Wi-Fi interspersed with being asked if I’ve considered turning it off and turning it on again
