    @chriswb @O2 No. Plus it says No Service where the O2 logo should be. I might try the SIM in my O2 iPhone.

  • thebaldfather Hugh Pollock (@thebaldfather) reported from Belfast, Northern Ireland

    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • McGuinnessKevin Kevin McGuinness (@McGuinnessKevin) reported from Belfast, Northern Ireland

    @o2 any chance you can sort out the masts in Belfast.. really slow connections and dropped connections, I’m even with o2 (was with you when it was BT Cellnet) I’m with sky who use your network but I know of o2 customers having the same issues. #o2network

  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

    @O2 Thanks. How do we unsubscribe from this ****? We pay for 5 contracts and do not wish to receive these messages particularly on children’s phones.

  • apallan ANN P V ALLAN (@apallan) reported from Belfast, Northern Ireland

    @Girlzmum Very poor service from @O2 especially to a front line worker in the NHS #NHS who needs her phone.

  • Watsonmydear Christine #StaySafe #SaveLives Watson 💙 (@Watsonmydear) reported from Belfast, Northern Ireland

    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 👇

  • VModifiedMind Vince (@VModifiedMind) reported

    Why is it that @O2 still sucks so bad for data? If it works at all it's slow, not just a little bit, but tragically so compared to other operators. Doesn't matter where I go, it's always bad.

  • Anthonylexton Anthony Alex (@Anthonylexton) reported

    @GemimaMoomin @O2 I got the 14pro Max. EE quoted £83 a month. Just get the phone from Apple and then a sim only deal. Got the pro max down to £60 a month with sim only deal as well. My Partner is paying the same for IPhone 12 on a worse sim plan because she got both phone and sim from EE

  • DWooBox13 Darren Woolston-Box (@DWooBox13) reported

    @O2 on 5G might be the biggest con ever. I’ve never, ever had 5G be anything other than totally useless.

  • liamrun Liam McCabe (@liamrun) reported

    I don't know how good or bad @O2's customer service is because I cannot engage with it as it is constantly busy #pleasetrylater #hopeless

  • KellyFriendPR Kelly Friend (@KellyFriendPR) reported
