    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • sparkloaf26 mark cording (@sparkloaf26) reported from Barnet, England

    @O2 this is a joke my signal is pants i better get money off my bill looks like ill be saying good bye when my contract us up your a joke

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • marcwhufc marc foley ⚒ (@marcwhufc) reported from Barnet, England

    @o2 your service has been shocking nearly 2 weeks and my daughters Apple Watch for Xmas not here. Now by all accounts best to start the order again as will be quicker and wait a week for deposit to be put back in my account 🤬 look at your dm’s I’m in them 2 replies so far 🙄

  • mesner5 Mark Esner (@mesner5) reported from Borehamwood, England

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

  • _TaylorJake Jake Taylor (@_TaylorJake) reported

    @jibbajabbasteve @O2 I used to be on 02 when I kept seeing these issues occur. I'm currently on ID which piggybacks the 3 network and I get very good coverage even on 5G on my Samsung S22 👍

  • robhetherington Rob Hetherington (@robhetherington) reported

    Everytime the subject is raised the standard @O2 response is that it is a busy area! Every single day I am in the office, since I switched to O2, even at 3am in the morning! Doesn;t sound like busy, sounds like poor infrastructure and no bandwidth!

  • AinsleyAllister Ainsley Allister (@AinsleyAllister) reported

    @O2 The village of Llangennith where we live has been experiencing problems with Wi-Fi mobile calls since December! We can be speaking to a person and then the call will drop out for about 10 secs before reconnecting.. conversation lost! 😡 Mast or Wi-Fi problem?

  • leannebull1985 leanne bull (@leannebull1985) reported

    @O2 I'm confused as my phone has worked perfectly fine up until today so how is this bolt on that should have been on not on and only caused issues today .

  • richa_michael Michael Robert Richa (@richa_michael) reported

    @O2 Due to a medical condition I pay extra for unlimited data so I don't have to rely on WiFi if I'm walking to find a place that has WiFi and I need assistance what do I do then. You have not provided a service for over 5 months that's a breech of contract

  • toriallenmartin Tori Allen-Martin (@toriallenmartin) reported

    @TwoStoreyADL @O2 Glad it’s not just me, I was honestly thinking my phone was broken! I think I will consider changing - I even lose it in central London which is a nightmare for maps etc! Sorry you’re struggling with it too though. X

  • marctva marcos (@marctva) reported

    @O2 guys what’s going on? No signal now for 3 days. Having to use Wi-Fi and hotspots!!

  • rossi_hatter Liam Ross (@rossi_hatter) reported

    @O2 had no signal at all for a while now what’s going ??

  • silentobsello mamon (@silentobsello) reported

    I think @O2 has the absolute worst service. A simple number transfer is taking days and the customer service keeps hanging up on me. So utterly incompetent.

  • jjmib jemma (@jjmib) reported

    @demelza1211 @tomlister @O2 He's saying that o2 are telling him to use WiFi calling, if he's not home yet has to use his data for these calls - but the data signal is shocking so can't
