  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • farellmichael Michael Farrell (@farellmichael) reported from Dublin City, Leinster

    @O2 hi. My friend’s UK mob stolen in Dublin. Need to cancel/freeze fone account. Help!!

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @o2 can someone help me please. I'm a new customer, I have transferred my number over from old provider. Phoned Monday gave the pac code about 2 or 3 o'clock. I am able to call out but incoming call going to voice mail & not ringing out when the mobile is on.

  • Sillyshib Siob, Princess of Yorkshire 💙#FBPE #FBR (@Sillyshib) reported

    @WasOnceLoved @O2 Can’t get any service from anyone these days

  • SimonMP4 Simon MP (@SimonMP4) reported

    @O2 Hi, I've raised an issue with coverage at TN25 4PS. I've had weekly texts saying you have the parts to fix it. When are the engineers scheduled to fix the issue please?

  • dkoblintz damian koblintz (@dkoblintz) reported

    Why is it that every time I go to an @O2 @O2ForumKTown venue I'm forced to download an app that doesn't work? Won't be able to go tonight because of @seetickets failures (and of course, no customer service out of hours or alternative if app happens not to work)

  • beckiewhelton Beckie (@beckiewhelton) reported

    @O2 absolutely shocking service. Trying to get a new phone should not take 3 hours and counting

  • ShazFilms Shaz Acess All Areas 🎬 (@ShazFilms) reported

    @O2 @iamchris20200 Im sorry whoever you are running this twitter account please dont make out us the customer just missed out due to popularity when in truth you never released the deal. Maybe go find out what actually happened instead of blaming us.I was on 5 mins b4 like every week so no excuses

  • drunkp1rate Emma Pirate (@drunkp1rate) reported

    @O2 is there an issue with service in Manchester? Since I’ve swapped to o2 my signal has been shocking!

  • samg932 samg93 (@samg932) reported

    @O2 I have followed all these instructions before it makes no odds it's not good enough when I am paying for a service I am not receiving, especially in these types of circumstances

  • CitizenJames007 Biff Howard Tannen (@CitizenJames007) reported

    @O2 Unfortunately not otherwise i would have driven the phone back. Went to an 02 store today, they said the mast should be fixed sometime next year, so no urgency i guess. One positive i will never use you again and urge friends and family not to either.

  • mckay1402 Jimothy Mckimothy (@mckay1402) reported

    @WasOnceLoved @O2 Network is awful too
