  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • Steve_Edwards77 Steve Edwards (@Steve_Edwards77) reported from Hertfordshire, England

    @westspice @O2 Awful service for me today!

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

  • optimismsflames Number 6 (@optimismsflames) reported

    @O2 No voice, 4g data or messaging on 7 devices and yet you coverage checker say no issues in our area!!

  • wh4tth3puck Dan Breen (@wh4tth3puck) reported

    Have just received a scam call claiming to be from @O2 with a 40% discount. This appears to be an account take over scam. If you receive this, it will sound genuine. Hang up and contact O2. DO NOT GIVE OUT SECURITY INFO OR PASSCODES - even as a joke.

  • MoulayOf Moulay Of (@MoulayOf) reported

    @VodafoneUK @mouthwaite You are too expensive Guys, but reliable Signal as good as @O2 :)

  • MarkH_Photo Mark H 💙💚❤️🏥 (@MarkH_Photo) reported

    @O2 No. I've spent an hour on the phone just to get an upgrade sorted before speaking to customer servs for 30 mins. The upgrade offer is only valid for 72hrs and I have no intention of going through all that again because it takes you 5 days to fix an error you made.

  • busdriver_kenny BusDriverKenny (@busdriver_kenny) reported

    @O2 Why are you so incapable of providing a stable mobile internet service?

  • GeorgeShanks91 George Shanks (@GeorgeShanks91) reported

    @O2 @AdrianMcCann2 Ive only ever been with O2, 0 issues in about 15 years

  • FallonBarton Fallon Barton (@FallonBarton) reported

    Anyone else on @O2 losing signal constantly 😭

  • Dannii2512_TW Danielle Kempster (@Dannii2512_TW) reported

    Got to say glad I’m not a @VodafoneUK customer, sadly my mum is, 5 calls to try & get a human! Automated service is crap & just cuts you off! Had a General question & didn’t like it I couldn’t put her on phone, bit hard as she in hospital 😡 might look to switch her to @O2

  • MarkH_Photo Mark H 💙💚❤️🏥 (@MarkH_Photo) reported

    Now been 1hr in the queue to speak to @O2 customer services to terminate my contract. *sigh*

  • JustCld Justin (@JustCld) reported

    @jaguar pivipro becoming every bit as problematic on my #FPACE as intouch control pro was on my Evoques. Constantly forgets profile. Spotify and incontrol need to be reset as they work then stop.4g signal from built in sim poor maybe you should ditch @O2 as their coverage is 👎
