    Been an @O2 customer for about 10 years now. But absolutely baffled by their choice to increase rates alongside inflation, as well as RPI increases yearly. Absolute joke, plenty of cheaper better options for phones nowadays. Time to look elsewhere. Cheers @GarethTurpin 👋

    @O2 @ChrisJAH27 They are busier than usual counting all the profits from ths 17.3% price increase they’ve just imposed on customers whilst continuing to provide an appaling service

  • Gazza_Noble Gazza Noble (@Gazza_Noble) reported

  • MarkBCars Mark (@MarkBCars) reported

    Every year, without fail, @O2 bill goes up! 17% increase!! My service doesn't improve 17.3%, on top of all the other increases. #o2 - Another UK Robbery increase.. Wonder what o2's profits are and will be.. #Theives #SeeYa

  • MarkEngland_ Mark England (@MarkEngland_) reported

    @O2 New customer here. I received my new phone & SIM today which I've just set up. I did give you a PAC code at the time of order so I can keep my old number from EE. Do I need to do anything to start the number transfer process or will my activating your new SIM start it?

  • ChrisWilmshurst Chris Wilmshurst (@ChrisWilmshurst) reported

    @AJeftech @O2 That’s exactly the issue I have. In my house their signal checker says I can get 4G speeds… I can’t even get signal in my bedroom.

  • IVP_SUCKS OSRS bhaskar (@IVP_SUCKS) reported

    I have a o2 sim card, classic pay as you go sim, had it since 2018, signal is low or drops out, the 2g signal, please explain @O2

  • foxespinky Pinky (@foxespinky) reported

    @O2 are you really putting the cost of my calls/ texts/ data by 17.1% from April? It’s completely unjustifiable, you cannot hang this on rising costs to this extent

  • Villabelieve We Are Villa (@Villabelieve) reported

    @jodielouiseart @O2 @EE are just as bad, however mine is only going up 14.4% as they go by CPI not RPI, still a disgusting amount mind

  • m333ruu1 Umair Ahmed (@m333ruu1) reported
