    @O2 I've tried the network tips, multiple times and still got the same issue. It's only the connection that's an issue at the moment.

  • KSC_Ltd KSC LTD (@KSC_Ltd) reported

    @AuntiePegg @ThreeUK @O2 Been with o2 since 2007 - Never had any issues and never changed providers :)

  • werbyWHUFC will (@werbyWHUFC) reported

    @O2 @Apple data in my area has been incredibly poor lately, and my mobile data has rarely been at 4g( canterbury area) any explanation??

  • InterstellarEU Ryan Lee (@InterstellarEU) reported

    @O2 can you help my 4G has been absolutely appalling. It’s so slow@even on full bar signal. It’s been like this forever. I’ve already reset my network settings. Nothings changed.

  • warpkid Sergio Russo (@warpkid) reported

    @rypw79 @EE Nope. Going to cancel my contract today and move to @O2

  • kirsst Kirsty (@kirsst) reported

    @O2 hello how do I cancel my Disney plus subscription? Didn’t even realise I was paying for it

  • Smell_My_Plums brian mccourt (@Smell_My_Plums) reported

    @O2 No point. I've been gathering evidence for 3 months now. This isn't a device issue or a once only issue. Its ongoing for months in various postcodes. How can anyone sort it when you don't have anyone to answer customers. I suppose its one way to say you don't have any complaints

  • alexminett Alex (@alexminett) reported

    @thestrayferret Which mast is out? The @O2 signal is pretty rubbish where we are but I do like @giffgaff as a provider 😕

  • Whirly90 Will Hearley (@Whirly90) reported

    @O2 my signal has been dropping off today any help as to why?

  • _xNatalie 🌸 (@_xNatalie) reported

    As someone who has been with them over 16yrs, I’d Love to know why I’m still paying over £50 a month for a contract that leaves me with no signal or 3G at best in the city centre, never mind being @ rural areas. @O2 sort your **** out, it’s 2021 this shouldn’t be a daily issue.
