  • bev_cheetham Bev Cheetham (@bev_cheetham) reported

    @O2 I cannot begin to tell you how disappointed I am with your network. I’ve spent 5 hours today with no service. It’s totally rubbish!

  • TerryQuinn10 Terry Quinn (@TerryQuinn10) reported

    @tescomobile @O2 This is absolutely disgraceful, to be honest it's bloody disgusting. Why are we still 1 month later without signal when your mast apparently has been fixed. Can only use my phone on WiFi 😡🙄

  • bev_cheetham Bev Cheetham (@bev_cheetham) reported

    @O2 Yes but I cannot get signal to use this app!

  • celticmaz04 CTM (@celticmaz04) reported

    @O2 It's absolutely nothing to do with what I can do it's the coverage. The signal has been piss poor for days.

  • idlewildgirl Sarah (@idlewildgirl) reported

    @our_je55 @bfafleck @O2 I’ve been chatting to them and they just say the mast near me is broken but it’s everywhere

  • ChrisInSilk Chris W (@ChrisInSilk) reported

    @O2 Your network in the city centre of Manchester is ATROCIOUS! Full bars, on 4G and can’t even send a WhatsApp. Friend I’m with, also O2, same issue. It’s basically unusable. Friend on @EE no issues at all. I want out!

  • _i4ani You planned this (@_i4ani) reported

    It has been 8 days since I have had no mobile phone service. Does it really take this long to fix your mast? @O2 #o2
