    Can someone from @O2 please help. I've been trying to call to cancel my phone and pay a bill but it gets to an hour on hold and cuts off...

  • ashhbitchh 𝔄𝔦𝔰𝔩𝔦𝔫𝔤 (@ashhbitchh) reported

    @msvnoir @O2 Ugh that’s so annoying. Sorry I can’t help more😩

  • SBforeal2 SB 🇯🇲🇬🇭 (@SBforeal2) reported

    I need @O2 to explain why their network is so slow. Everywhere I go I’ve always only got two bars 🤨😒

  • elstoleno Rachel Bell (@elstoleno) reported

    @o2 any chance of a service check or update in Sunderland city centre? Two of us showing 3 bars/4G but can load basically nothing. Idek if this will post, a tweet with 4 photos in couldn’t.

  • Farnboroughnol1 Farnborough@nolettinggo.co.uk (@Farnboroughnol1) reported

    @O2 I am starting to seriously regret having O2 as both my business mobile and private provider. Very disorganised company who can’t even get their own automated phone service working properly

  • dea202088 aedt202088 (@dea202088) reported

    @O2 data is so slow on both 3G and 4G - it’s taking 2 mins to load a webpage on 4G and the 3G ones are just not loading at all. Network checker says area is busy but I can’t use my phone at all really as nothing is loading?

  • frvic93 frvic93 (@frvic93) reported from Edinburgh, Scotland

    @O2 is there something wrong with your mast at EH15 1DA? My friend was getting terrible speeds (below 1Mbps) there yesterday

  • LJ19714 LJ1971 (@LJ19714) reported

    @O2 recently delivered reconditioned iPhone X voice calls poor quality. People on other end of line says my voice fades in and out or like under water. Calling from my house. No similar problem with old iPhone (5s). How do I seek help. Can’t call you because you won’t hear me!

  • BrokenRobot TASTY LIKE A RAINDROP, BrokenRobot's got The Look (@BrokenRobot) reported

    @tiffstevenson @O2 Serbia's network doesn't enter into mutual roaming agreements with anyone else's networks, so those other networks pay enormous fees to Serbia for use of its network.

    Sick of having no signal/service now. @O2 need to sort their **** out.
