    @SkyHelpTeam @O2 why is the network signal so poor/non existant in Cwmbran NP44

  • AdamLee2011 Adam Lee (@AdamLee2011) reported from Newport, Wales

    @O2 Already with o2 for my mobile and they are brilliant. This was for MiFi, someone recommended three but the signal is terrible. Waste of money.

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @pinecone95 @O2 It's coming along slowly but surely. No sign in Barry or Cardiff yet.

  • paigebuckingham Paige🧚🏻‍♀️🌸 (@paigebuckingham) reported from Cardiff, Wales

    Anyone else on @O2 and get literally no signal? I’ve had my baby’s doctor and hospital ring me many occasions and can’t get through to me!

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia I feel for you, if @O2 and @virginmedia do merge, I'm leaving at the earliest opportunity. @virginmedia leave me a little cold and with no confidence as a customer.

  • catlady_cez Cez 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@catlady_cez) reported from Cardiff, Wales

    @O2 hi is there an issue with your network in cf14? Havent been able to get 3g or 4g since yesterday?

  • bethanjane22 Beth (@bethanjane22) reported from Cardiff, Wales

    When I renew, @virginmedia offer free AirPods with some plans and @O2 do the same! So much for customer loyalty, they just want more and more money! 🤬

  • JdBowns91 Jade Bowns (@JdBowns91) reported from Barry, Wales

    @O2 on the website it says to contact your customer services to change my name and other issues I want to discuss yet the only way I can get through to someone is to say I’ve had fraud occur! All I want to do is speak to someone why is it so hard. Chat is also unavailable

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    Also when I highlighted my issues over the phone and through the Webchat @O2 do not seem very concerned or understanding 😔

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    There is always some kind of problem with my @O2 order. Its even more frustrating seeing on here people have just walked into the store and been able to collect the phone without the relevant email saying its ready to collect. How do they know they are distributing the right

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia @O2 Good luck to you and don't take any sh*t, you should be fully compensated for the absolute inconvenience. We had a little problem with our provider and they where excellent, understood the issue and before we asked they compensated us.

  • clareoj Clare Osborne Jones (@clareoj) reported from Cardiff, Wales

    @O2 still waiting for a refund on a returned phone case since July...numerous phone calls resulting in last one on 11/10 we will take it off your phone bill for you but full amount taken today. Can’t get through on phones can you please advise as I’m pretty fed up with service

  • flowersshanice S H A N I C E (@flowersshanice) reported from Cardiff, Wales

    Hi @O2 I’m in desperate need for someone to active my new sim (had an upgrade) as I’m unable to text or call out viseversa. My o2 isn’t solving the issue either.

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

  • StuRobson Stuart Robson (@StuRobson) reported

    @o2 my son and I have locked his iOS MyO2 app account. Neither of us can get the secret answer correct. Even though we know that the answers we have provided would surely be one of them. Help.

  • PhilThomas19 Phil Thomas (@PhilThomas19) reported

    @RqzvE @O2 @O2 so in what order are you giving these out to customers. Like others I have been a customer of yours for 13 years and all I seem to get is a bill rise!

  • SuarezFusters Jose Suarez (@SuarezFusters) reported from Ealing, England

    @O2 anyone can please tell me what’s going on with the network in W13 9 I can’t receive message and call from last Saturday, I guess I need to change my provider.

  • MixedMagicWoman Teresa Fowler (@MixedMagicWoman) reported

    @O2 Perfect. This is just what I needed. Shame the customer service rep I spoke to on the phone today didn't make any mention of it...nor did the sales rep I saw in person in your shop yesterday!

  • thelibretto jlc (@thelibretto) reported

    @O2 hi I’ve had an email saying I’ve changed my tariff but I never changed it, how do I find out what’s happened

  • _JamieHughes_ Jamie Hughes (@_JamieHughes_) reported

    @O2 Went into the store to collect it. Full signal but can’t make or receive calls. Plus mobile data is not working.

  • grshorwich Godwin Stewart (@grshorwich) reported

    @O2 have you flicked a switch somewhere near the PR4 post code? Data speed is still rubbish but I'm getting a full 3.5G signal. Until now, we only had very weak EDGE here.

  • Elaniel84 Josh Canavan (@Elaniel84) reported

    Utterly incompetent @O2 I ended contract early due to change of your terms and been given three different final amounts to pay. I also don’t understand why I’m paying past my 30 days notice due to being able to cancel early due to this change.

  • _JamieHughes_ Jamie Hughes (@_JamieHughes_) reported

    @O2 just got a new sim. Can’t make calls and online chat is not working. Please advise.

  • John74245963 jonpluke (@John74245963) reported

    @O2 why is the mobile data connection so bad in Torquay Uk, I keep losing connection
