    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • 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

  • 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

  • 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!

  • 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.

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • hadhamlane Andy Lane (@hadhamlane) reported from Bishop's Stortford, England

    @O2 ...and then when you’re signed up they change your deal to make you worse off. #O2 reducing the friends & family discount for a loyal customer is the last straw for me.. #O2

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • 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!

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

    @westspice @O2 Awful service for me today!

  • 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.

  • 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!

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • sjetaylor Sarah Taylor (@sjetaylor) reported from Loughton, England

    @Johnny_Slack I’ve been with @O2 for 20+ years but once contract expires in August will be moving suppliers as they don’t look after their customers - no loyalty perks nothing - poor coverage where I live and work so it’s bye bye

  • dorkipedia — rylee/ry 🦦🏳️‍🌈. (@dorkipedia) reported

    @O2 I’ve not had service in 3 days and I can’t log into my app because it asks for a text, which I can’t get because I have no service. What the heck is going on????

  • Lisa123hHall Lisa hall (@Lisa123hHall) reported

    Hi, I wanted to return an upgraded phone. I was sent two Jiffy bags, although only one marked on the system. Now o2 are unable to find the phone even though it was delivered on Monday. The first person told me they sent the extra Jiffy bag for accessories. Can anyone help? @O2

  • MrDunkie Dunkie (@MrDunkie) reported

    @O2 I am trying to keep my mobile number with you guys but can't get hold of anyone to help and the online switch keeps failing?????

  • AdrianJOSmith Adrian J O Smith (@AdrianJOSmith) reported

    @bipolarmessxo @MarkEvansO2 @O2 Smurf if that’s seriously the message you took from all the incompetence outlined in my six tweets then that says a lot. O2 should be trying to fix offers that don’t exist and making the app accessible but nobody gives a ****. It’s one attitude. PAYG customers are “second class”

  • SprottSharon Sharon Sprott 🏴󠁧󠁢󠁳󠁣󠁴󠁿❤️♑ (@SprottSharon) reported

    Is @virginmedia down again? Pay for it, get boosted because I'm with @O2 and I still can't watch a single thing on my fire stick. This is getting beyond a joke now!

  • Ak_Craze1 Ryan glover (@Ak_Craze1) reported

    @O2 @virginmedia I need help with accessing my account, I can’t find anything to help me and I can’t contact you, I need to reset my password but the like says to contact customer service
