Latest outage, problems and issue reports in Windsor and nearby locations:

  • 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.

  • 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

  • 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

  • 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.

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

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

  • 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.

  • 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.

  • 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?

  • 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.

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

    Poor network in Se6 @O2

  • 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!

  • 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? 😲

  • 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!

  • 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.

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

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

    @O2 Why won't you reply to my dms? Called customer service and got absolutely nowhere

  • Dougelove1 D T ©®™ (@Dougelove1) reported

    @zzoommplc @O2 @BTCare Yes and your engineers are working to fix the problem, but have been without fibre for 4 days now.

  • AustinCozypants Amanda Austin (@AustinCozypants) reported

    @O2 Trying to upgrade and finish payment online and it is not working. Please do not ask me to telephone!

  • gethinbach GethinMichaelDavies (@gethinbach) reported

    @O2 A network you pay for that actually works 🤔

  • PrincessStar83 Sarah S (@PrincessStar83) reported

    @O2 can someone please contact me regarding my late dad's account. I've been in store and passed on to your customer services bereavement team and have so far spent over 6 hours on hold to then be told I'm going to have a call back within 24 hours and it hasn't happened.

  • ErikDoIt Erik de Wit (@ErikDoIt) reported

    @O2 No - unfortunately i wont avoid sending multiple messages. That will happen when you actually fulfil on the promise from over 2 weeks ago, 10 days ago, 7 days ago, 5 days ago to resolve an issue. You have yet had to have the decency to get in contact out of own accord.

  • ErikDoIt Erik de Wit (@ErikDoIt) reported

    @O2 @o2 not replying to phone problems or @o2 not responding to their own dm requests

  • brough_yacka tony gray (@brough_yacka) reported

    My mobile was hacked 24/09, I reported it to @O2 26/09. Was told the fraud team would ring me in 5 working days. It’s the 8th day now, still no phone and still can’t use my mobile. I’ve been with o2 since the BT Cellnet days. Unacceptable customer service, o2 days are numbered.

  • VickiHazledine Vicki Hazledine (@VickiHazledine) reported

    @O2 please see my DM. Your website is broken and I need to download my bills

  • MardieMostly MostlyMardie (@MardieMostly) reported

    @O2 Thank you- it’s just a public place, as I’m out. But now connected to wifi. Your signal in Newquay and St Austell is faulty. I’ve received a text saying there’s a fault- when will you have a fix for it?
