  • 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...

  • LairdDourka Andrew Dourka-Laird (@LairdDourka) reported from London, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • JamesSharp87 James Sharp (@JamesSharp87) reported from Witham, England

    Hello @O2 I’ve accidental damage to the rear of my iPhone 11 Pro Max. Only had the phone 3 months so will it be covered under warranty?

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • 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.

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

  • RyanSchaverien Ryan_Schaverien (@RyanSchaverien) reported from Chelmsford, England

    @O2 Extremely slow data coverage for the past 3 weeks.... any help?

  • KJDalby Kate Dalby (@KJDalby) reported from Chelmsford, England

    @O2 urgent my new provider activated the PAC code provided by you. Their sim card does not work because apparently my device is locked with you. I cannot text you to get it unlocked. Please help asap.

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Great Leighs, England

    @O2 The fact it’s in 3 seperate locations, where my current projects are located, suggests it’s on your side. To use the excuse that there is too much traffic is also ridiculous as means you have over sold your network.

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • IanMaxy94 Ian Maxwell (@IanMaxy94) reported from Billericay, England

    Is transferring of SIM cards supposed to give me no service on both my old and new phone @O2??

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

  • BBGSHQ Banner 🔬🧬 (@BBGSHQ) reported

    @O2 @JakeEllisimo O2 have been horrid in my experience. Been with them for 6 years purely for o2 refresh but after this contract ends I’m switching.

  • chelsearlxo crhiled (@chelsearlxo) reported

    @O2 I swapped to another network but now I can’t log in to find out what my final bill will be and the text service isn’t working

  • deborah_bowie Deborah (@deborah_bowie) reported

    @O2 Despite calling customer services to resolve it the lovely advisors cannot do anything until an email inbox has been checked by a department they cannot contact unless they also email that inbox. They can check emails that have been sent to me though 🤯

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

    @O2 @Gropinvillain In all these years I’ve been with @O2 I’ve never ever had nothing for bro g a loyal customer, maybe it’s time I cha he networks after my contract is finished!!

  • RedDwarfGirl Rhian 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@RedDwarfGirl) reported

    Hi @O2 any issues with signal in the Swansea area? I haven’t got any at all. Thank you.

  • willall86 Willall86 (@willall86) reported

    @O2 I returned a phone to you because it was very poor. When calling and using chat to see if you've received it, I get a different time scale provided every time. Again poor service from o2

  • someth1nglondon someth1nglondon (@someth1nglondon) reported

    @O2 Years being a customer. Have paid thousands always on time. Moved to Wales, you have not been able to supply a usable line. Paid up until the end of my contract with no fuss. And now you have taken £133 pounds for the pleasure and no answer on customer service. #o2 #service

  • ashleighsaidso Ashleigh.☮ (@ashleighsaidso) reported

    @O2 currently experiencing no signal and can’t get through to anyone to find out what’s going on and no issues showing on the service checker... can you help?!

  • ShamilaYounis Shamila Younis (@ShamilaYounis) reported

    @O2 absolutely disappointed with the customer service received by o2. Disconnected line over 3wks ago. Keep saying tech team will help. Not heard anything. All incoming cancelled too. Feel frustrated and sad

  • scrumpypaul Paul Adams (@scrumpypaul) reported

    @O2 hi. I bought some headphones for my child in April (JBL JR300) but they're not working. Can I have them replaced please.
