  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    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.

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

  • 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

  • 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

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

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • 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

    @kiedrh @VodafoneUK @O2 Wrong though isn’t it mate? My thoughts are keep you’re current customers happy then every other new customer is a bonus.

  • BenjaminShackl5 Benjamin Shackleton (@BenjaminShackl5) reported

    day 3 of no outbound call service with @O2 . Basically being ignored at this point. Can’t speak to my therapist, can’t speak to my support network as they have landlines. Can’t call ANYONE. Just took out a brand new contract, what GROSS service?

  • subhendudey Subhendu Dey (@subhendudey) reported

    @O2 is there any fault in your network. Phones are not working!!!

  • howardhardiman Howard Hardiman (@howardhardiman) reported

    @sneezy7purple @O2 Aagh, and if she's not staying there for long, it's not like you can buy a pay as you go SIM with data or anything because each ward might be a different network!

  • MartaParente9 Marta Parente (@MartaParente9) reported

    @O2 ridiculous customer service, over 2 hour wait time and still counting to actually get assistance with an issue ???
