    @O2 is your online chat down? Been trying for 2 days to speak to somebody on there?

  • Stuckinlondon1 Freyja (@Stuckinlondon1) reported

    @O2 I have a problem.I wish to server ties with my brothers line; which happens to be on my a/c. My phone bill is always ridiculous because he’s using me to buy games in the App Store and I’m tired. How do we transfer the line to him so that I can be free?

  • ukb00tlegs 🇺🇦 Graham 🇺🇦 (@ukb00tlegs) reported

    @O2 Even tho I have 3G not 4g. It says I haven’t enabled data. This is day 1 after changing contract from @EE How do I get live support instead of that WhatsApp thing?

  • andyrennie Andy Rennie (@andyrennie) reported

    Glad I can rely on @O2 for a decent reliable 4G phone signal at my home location…….NOT ! Going on for too long now and an offer of a £10 sweetener doesnt cover it

  • Keith_Lynn Keith Lynn  (@Keith_Lynn) reported from Sevenoaks, England

    @O2 can you please explain why the signal is so poor on the train, motorway & generally near where I live (TN26). I’ve just got back from Crete and the signals are brilliant 4G everywhere, so much so I was in the middle of a lake, top of a mountain & I get 4G???

  • RichardTonry bluenose mucka (@RichardTonry) reported

    @O2 the year of 2022 and still struggling to get any decent network coverage In Cornwall! Why can EE and Vodafone seem to have sorted any issues? #o2 #o2poornetwork #o2serviceissues

  • RangersBear55 𝑹𝒂𝒏𝒈𝒆𝒓𝒔 𝑩𝒆𝒂𝒓 (@RangersBear55) reported

    Anybody have issues with @O2 coverage/reception? Been going on for months now. Can't have a phone conversation with my folks who stay 10mins away. My phone doesnt ring then i get a vmail msg 😡 Mobile data coverage is horrendous now too. Time to look at @EE or @VodafoneUK

  • Stephen29786917 Stephen Murray (@Stephen29786917) reported

    @O2 I received a random text this afternoon saying my sim swap had been activated, shortly after I lost all service. I have been on live chat for 2hours with no reply, now it says the service is busy (it’s pre-11pm)…can you DM me urgently..you run my Wi-Fi and mobile services

  • bertbettiss bertbettiss (@bertbettiss) reported

  • martincottle Martin Cottle (@martincottle) reported

    @O2 for the love of God, will you talentless fuckeyed cockhounds please, PLEASE, provide me with a semblance of signal anywhere, ANYWHERE, within a billion kilometres of my house, or indeed anywhere on planet earth.
