    @Beth251993 @O2 It's that bad, I've had to activate a 2nd SIM through @EE to be able to use my device.

  • vickiredford Vic ✌🏻 (@vickiredford) reported

    @O2 I have had no signal all day, I’ve reset my network settings, taken the sim out and put back in. Turned off and on etc. I have soooo much I need to do, why have I got no signal?!

  • craig18645879 craig (@craig18645879) reported

    @O2 when you pay £85 a month for a service that is not provided. The whole of August with 3G and no communication or accountability for a terrible service. Can anyone at @O2 provide a legitimate response for your misgivings. Enough is enough @MartinSLewis

  • cornelius_mark Mark Cornelius (@cornelius_mark) reported

    @SFL2326 @david_bryden @O2 I wouldn't.. they use 02 network

  • ant_nffc 𝙰𝚗𝚝 (@ant_nffc) reported

    @truckerjoe82 @O2 @EE Probably best o2 coverage is terrible , hardly 5G anywhere. I’d recommend three if sim only

  • CasMillar Caroline Millar (@CasMillar) reported

    Hi @O2 you sent me notification that you have shut down 4g for me in USA. I also can’t call out after paying upgrade to do so. Can’t get in touch to activate by any means. How do I resolve?

  • LauTay0609 Laura Taylor (@LauTay0609) reported

    @O2 can you put in the right direction? I need to pay an outstanding bill. My phone was disconnected 3 months ago. Can you help? Thank you

  • Jimbobthon James Richards (@Jimbobthon) reported

    @O2 Unless you can fix the mast in the Bristol area, not much help can be done.

  • mumsy_mary Mary Rees (@mumsy_mary) reported

    @O2 how do we get help? My data has run out immediately I’ve topped up and it shouldn’t have done. I’m at home, using WiFi. Tried calling got cut off. Went through “start a conversation” on app to be told no one available. I don’t want to top up again if it runs out in 24 hrs.
