    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

    @JoeSims10 @O2 Look forward to no signal on the Portway Joe 🙃

  • jamieriddell Jamie Riddell (@jamieriddell) reported from Cardiff, Wales

    Hey @O2 who can I talk to about unlocking a phone. I've paid up and out of contact. Online form says no because of too many attempts ( no idea what my customer service code was) but I have all my account details.

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    @jolilford @O2 Your kidding me!!! I have contacted customer services 3 or 4 times. Shocking service

  • HywelButcher Hywel Butcher (@HywelButcher) reported from Cardiff, Wales

    Top tip - don’t join @O2 - incompetent and useless! First no 4G, now no signal or data at all 🤯

  • andrewhillandCo andrew hill (@andrewhillandCo) reported from Abercynon, Wales

    @O2 @JohnnyMercerUK bit late that isn’t it - I think he has just a few followers who may have seen this and your ‘standard good customer response’

  • 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!

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

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

  • ieuanbeal15 Ieuan-Rhys Beal (@ieuanbeal15) reported from Cardiff, Wales

    @O2 your live chat service is garbage. 15

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Pontnewydd, Wales

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

  • 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! 🤬

  • Waldron_Diana Diana Waldron (@Waldron_Diana) reported from Cardiff, Wales

    @O2 can u please help. I have been trying to pay my final bill with you for ages. It’s only about £20,I don’t need harrazing letters&emails to prompt me to pay...I just need u to let me pay. I have called&been online to make payment, but you don’t seem to want to take my payment

  • 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 😔

  • daunce4thstreet Garry Dauncey (@daunce4thstreet) reported from Pontypridd, Wales

    Never use @O2 recycle! sent them a phone that was in perfect condition & now they say the phone is damaged and are offering peanuts for it. If it’s damaged blame the flimsy packaging you send.

  • 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

  • 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.

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RobBruceK @ThreeUK @O2 @EE @VodafoneUK No awful. Just spent 5 days with no data/calls due ti Insufficient bandwidth. My family and friends who were with O2/BT/Vodaphone had no problems. Worst ever. So regret leaving previous provider last month. Their coverage checker is inaccurate too

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    Totally disappointed with @O2 customer service. A number transfer from a consumer account to business took 8 days when I was told it would take 24 hours. 3 phone calls to customer service and still not 100% sorted. #totallycrapexperience

  • tomgstott Tom Stott (@tomgstott) reported

    @O2 Please do because it's gone beyond platitudes now I just want some service. I can't listen to music, video call my sick dad, pick up with emails or teams calls access digital banking if I'm out the house in my home town. Even Twitter is unusable and to that's mainly text!

  • minxtheminnie Nyree D Scott (@minxtheminnie) reported

    @O2 Thank you, I am hoping that may have solved the issue at home too, but will come back to you if it hasn't!

  • Vagabond1107 ☭ 卡里德 🇨🇳 ☭ خالد🇸🇦 (@Vagabond1107) reported

    @O2 could you confirm of availability Wifi calling and 4G calling for PAYG customer?

  • murphy_doodle Murphy_Doodle (@murphy_doodle) reported

    @O2 She has emailed about her unhappiness with the service and just received generic emails back. As she has been a customer with O2 for over 20 years she was hoping for better service 😳

  • Ronbus87 Colin Farthing (@Ronbus87) reported

    @O2 Hello I am an O2 customer. My contract is 5gb of data. I only have 1.5gb left.

  • ThomasEdmund71 Tom Richardson (@ThomasEdmund71) reported

    @O2 Fixed the issue!! You’re having a laugh. It’s no different - not one bar of signal. I live in a large housing estate just outside Maidstone. I’ve had better signal in the middle of nowhere in Cape Wrath.

  • Vagabond1107 ☭ 卡里德 🇨🇳 ☭ خالد🇸🇦 (@Vagabond1107) reported

    @O2 I am an O2 customer since 2010 at least do offer it

  • chloackerley Chlo Ackerley🌞 (@chloackerley) reported

    @HT_95_ @O2 I have the same problems too and I live near Manchester, o2 shite

  • Cullimore Darren Cullimore (@Cullimore) reported

    @O2 terrible signal at DT64PT Coverarge checker says full 3g and 4g. Correct. I have full bars, but it's like dial up and unusable. #SameSpeedAsCaptianSlow

  • Vagabond1107 ☭ 卡里德 🇨🇳 ☭ خالد🇸🇦 (@Vagabond1107) reported

    @O2 Every UK network offered it to their PAYG customers except your network do offer it as soon as possible
