  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • UKGeocacher geocaching.uk (@UKGeocacher) reported from City of London, England

    Recently moved back to @ThreeUK on a sim only plan and it’s blooming awful in terms of speed or coverage in central London. Thanks to my @O2 work E-sim I actually have signal!

  • jamesmurray07 James Murray (@jamesmurray07) reported from Camden Town, England

    .@O2 despite asking me to DM you nobody had responded and the link to the chat doesn’t work (also not working on myO2).

  • Paula_Griffin65 Paula Griffin 🏳️‍⚧️ 💙💖🤍💖💙 (@Paula_Griffin65) reported from Camden Town, England

    @O2 Hi, currently log into 02 Wi-Fi in places like Costa etc but need to change my details as the name it flashes up is incorrect. However it won’t accept either my email or my phone number to change details.. Help please!

  • JoshBates Josh (@JoshBates) reported from Paddington, England

    @O2 I got this sorted doing this however this is really poor service. This should be an easy, self-service digital journey. Absolute joke that this took 35 mins for both me and your staff. Total waste of time. Please feed back.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • NorthernlyExpo Andy Denial 📸 (@NorthernlyExpo) reported from Islington, England

    @O2 Just trying your Priority code in McDonalds but it’s not working. Just says it’s been used already.

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    @O2 authentic my account and not working???

  • fred6279 Fred (@fred6279) reported

    @KyleTSpence @MartinSLewis @O2 Their prices are horrible though, and their Giffgaff MVNO has worse speeds than proper O2 unlike ID Mobile/Voxi which are just as fast as Three/Vodafone.

  • Shannon73921835 Shannon Gibson (@Shannon73921835) reported

    @MyApocalypse_ @O2 Exactly the same problem for me! It's a joke.

  • selectasuave suavito (@selectasuave) reported

    @o2 3G signal in a city in 2025 is crazy btw… please sort it out.

  • charlielucy_ charlie (@charlielucy_) reported

    @O2 I have called twice this morning to get my data roaming sorted. You have added 2 ‘bolt-ons’, one which I was told would be removed but has not. My data roaming is still not working and you were meant to have a tech support reach out to me an hour ago!! Ruining my holiday!!

  • KrazyKirst666 Kirsty Stollery (@KrazyKirst666) reported

    @O2 All tickets will be gone by then! Never mind! 😡

  • briavelsjon Jon Pitts (@briavelsjon) reported

    @SanrioPublic @O2 @EE EE don't have a 3G network.

  • davidhblandy David H (@davidhblandy) reported

    @O2 Just received an email telling me you’re turning 3G off in Guildford. Only problem is the 5G you say is there doesn’t work and 4G isn’t available (replaced by the 5G that doesn’t work). So what do you suggest an O2 customer does in Guildford.

  • GGGENTOO GENTOO (@GGGENTOO) reported

    @REDDOC98 @ARMIGCE @O2 Same! It’s been a week now. Did you find a fix?

  • Roughman01 David Roughley (@Roughman01) reported

    @O2 Just a shame your network Barely works in the UK 😡 I can't use my data or log into my account!!!!
