    @O2 My data has been terrible recently, constantly on and off. Bad enough that my wifi doesn't work when I'm home, without having to try and connect to mobile data that doesn't work either 😩

  • Sly1036 Sly (@Sly1036) reported

    @O2 if on a normal post pay contract with a 5G Ready smart phone and O2 5G services are available, can users benefit from the new faster 5G service?

  • luke_craven Luke 🐟🐟🐟 (@luke_craven) reported

    @O2 Network has been down for the last couple of days in DN32 (Grimsby) area. Any indication as to when this will be be fixed? Quite important to me as I'm currently self isolating. Thanks.

    @O2 @O2 it’s the same network. The Transfer of ownership form that your advisors use is an internal transfer. Not an PAC.

    @O2 hi, no phone signal in my area since Friday (after storm). Have tried the usual turn off, take sim out but still nothing. Please PM to advise. Thanks

    @O2 Yep. Not much help to be honest

  • AteA1000chips Helen of Troy 💙🐝 (@AteA1000chips) reported

    @Copywright52 @unitedutilities @O2 It's such a big help and makes you feel like other people (strangers) understand and want to help. It's little things like this that really make a difference.

  • Linkmarine15 《⬡》 $link ¥ou ₩!n 《⬡》 (@Linkmarine15) reported

    @O2 still unable to provide a reliable service

  • cathcartboy Cathcart Boy (@cathcartboy) reported

    O2 must have the worst administration and customer services ever. Definitely changing tomorrow for sure. Sick of @O2 dysfunction. Irony is no complaints over actual phone service.
