  • 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 🤯

  • kdhanz KD Hansford (@kdhanz) reported from Mountain Ash, Wales

    @EE I'm fed up of your network in aberdare. It hasn't worked tidy for months and I have two contracts with you. Please sort it out or I'm leaving to @VodafoneUK or @O2

  • 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

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @O2 This has always been an issue. We are with giffgaff whom I believe use your signal. I have tried everything. I have even bought a booster, but the reception coming into the booster isn’t enough to even make the booster work. Very frustrating. I have to sit in a window 4 reception

  • Statto1927 Simon Hiscocks (@Statto1927) reported from Barry, Wales

    @O2 It’s CF11 8AZ. ardiff City Stadium. My point is that I can hardly get any connectiveity with a 4G signal showing. Someone sat next to me with EE can connect. Granted it’s a sports stadium but this was 60m before kick off with barley anyone in there. Happens every match 1/2

  • 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

  • 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

  • Welsh_PA Mark Edwards (@Welsh_PA) reported from Cardiff, Wales

    @PA_Stacey Oh yes @O2 love to go OTT on bill notification. It’s a shame they don’t put more emphasis on sorting out their weak/phantom 4G signal 📡 #priorities

  • ThisIsDanGuy Dan Guy (@ThisIsDanGuy) reported from Cardiff, Wales

    @O2 sucks that reduced the number of cafe Nero codes 😡

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

    Currently with @EE with no/very low signal at home address! Who wants to send me sim cards so I can see what network to change to! @O2 @o2 @ThreeUKSupport @VodafoneUK @ThreeUK

  • gavinlew Gavin Lewandowski (@gavinlew) reported from Butetown Community, Wales

    @ee need to kick a few cells around the Cardiff arena tonight very poor 4g coverage had to switch to your neighbours at @o2 for connectivity

  • Rhian1975 Rhian Langham (@Rhian1975) reported from Cardiff, Wales

    @O2 shocking attitude of customer service rep. Please get in touch.

  • LisardoVivas Lisardo Vivas (@LisardoVivas) reported from Cardiff, Wales

    @O2 @tig1985 I’m in cardiff with same issue

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @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.

  • 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.

  • CJLittlemore Callum James Littlemore 🔶 (@CJLittlemore) reported from Cardiff, Wales

    @O2 I woke up this morning to find I’ve been totally cut off. I can’t make calls, send texts or use my mobile data. All of this is kinda important for my work as I’m self employed - I can’t call your customer service line to see what the issue is. Can you look into it please.

  • 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.

  • Statto1927 Simon Hiscocks (@Statto1927) reported from Barry, Wales

    @O2 2/2 it’s like someone deliberately switches off the internet on match days, but I’m sure that doesn’t happpen.....😉 Signal is perfectly fine there usually, & if it’s vol7me of people, why are other able to connect seems like an O2 thing as my son & daughter also have problems..

  • 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’

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @teamIPSE Without a doubt! And phone signal! It is appalling how bad the signal is in parts of the UK outside of London! I am 4 minutes from the Cardiff city centre with no signal! #howareyoumeanttorunabusiness @o2networks @O2 @giffgaff

  • bharazi Alfie (@bharazi) reported

    @O2, Hi there, my 2 Odeon codes are not working. Have tried them from Friday and the site keeps rejecting. Please help

  • CamillaLatham30 Camilla Sally Louise Latham 🌸 (@CamillaLatham30) reported

    @O2 my signal is pretty bad at the moment? Any problems been reported in Cardiff?

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 @O2 why would the customer still have to pay for the contract for someone who would be deceased?

  • teambatman4 TEAM BATMANBOXING (@teambatman4) reported

    @O2 still no service 😑

  • Babyfarmgroup Victoria Miles (@Babyfarmgroup) reported

    @stephstwogirls @O2 I moved over to Sky mobile 2 years ago. Faultless, can share data and keep it if you don’t use it. We live in a known crappy area for mobile coverage and it’s permanently 4G and no issues so I’m pretty impressed Previously I’d been with Vodafone, but was disappointed many times

  • vickidoylexx Vicki Doyle (@vickidoylexx) reported

    @O2 not a happy customer. Upgraded my phone to a Samsung Galaxy S21 with 1 week delivery. As soon as i placed the order i had an email to say out of stock. Now you can't tell me when it will be delivered. Not impressed at all.

  • vickidoylexx Vicki Doyle (@vickidoylexx) reported

    @O2 That's not good enough. Basically you lied about availability yet still took out the contract. Surely you should give me some idea when to expect it?? Otherwise you will lose me as a customer as I'm not prepared to wait with no timescale

  • deablosantos James Dougal-#Actor (@deablosantos) reported

    Anyone else having major issues with @O2 ? I haven’t been able to make a call all weekend and they seem to not be doing anything on out it?
