  • BrendanB2 Brendan Bonner (@BrendanB2) reported from Belfast, Northern Ireland

    @O2 I wouldn’t recommend anyone buying online and redeeming your phone. Go to the store, you can’t trust any of the online and virtual services. Was a handling getting phone set up, getting help and they only give you 50% of the value they say (no matter how good your phone is).

  • kkanecelt kierankane (@kkanecelt) reported from Belfast, Northern Ireland

    @o2 is the worst shittiest network I've ever been on in my life

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport Just checked and its now saying the same for me! Apparently it takes a full 26 hours to get from Birmingham to Down 🙄

  • 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

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    Kudos to @O2 for customer service today. Recommend going via app ‘Start a Conversation’ section.

  • mcadam_rob Rob McAdam (@mcadam_rob) reported from Lurgan, Northern Ireland

  • 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.

  • AskkeithInfo askkeith.info (@AskkeithInfo) reported from Castlereagh, Northern Ireland

    @O2 Reece in your forestside store was a legend I ran through door cut off from world and all sorted for phone and lap top in 12 mins a credit to public service he’ll be snapped up by someone soon give him a pay rise and pat on back

  • 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.

  • UberGeekFanboy Fanboy (@UberGeekFanboy) reported from Belfast, Northern Ireland

    @O2 trying to phone through to return a phone and keep getting cut off? Wtf.

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    Great customer service @O2. Placed an online order at 6.30pm last night and arrived 4.45pm in Belfast.

  • GarethAJMiller Gareth (@GarethAJMiller) reported from Belfast, Northern Ireland

  • columcoyle Colum Coyle (@columcoyle) reported from Castlereagh, Northern Ireland

    @angelcosta78 @DPDgroup_news @O2 @AppleSupport I’ve sent a complaint to O2 asking for a refund of the three days I’m missing out on my device plan. They’ve already charged me!

  • billyjatkins billy (@billyjatkins) reported from Belfast, Northern Ireland

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

  • FiaNewell Fiona Newell (@FiaNewell) reported

    @O2 So I’m currently paying for a service I can’t use?

  • Danlaximus Dan Lax (@Danlaximus) reported

    Hey guys, can you help me with an myo2 app problem? When I login it shows a different name next to my mobile number? I can send you a screen shot? @O2

  • wilsondan Dan Wilson (@wilsondan) reported

    @O2 Order confirmed. 30th. I didn't expect it yet really. But do rather resent being upsold before it has arrived! I need to evaluate first whether the reception is better in my new house before considering transferring network. A point not absorbed by the caller.

  • Astr0Isha MRS WORLDWIDE LDN (@Astr0Isha) reported

    @MaisyandBonnie @O2 I’ve got the same issue

  • jonpod1 JW (@jonpod1) reported

    I’m done with @O2 . I live in a capital city (Cardiff) and I can’t even get a signal strong enough to talk on the phone. It says 4G/5G but it’s rubbish. Apparently ‘too many people are using it now’. Not good enough. #O2

  • gazjsmithy Gareth. (@gazjsmithy) reported

    @Karl_Downey I’m with @O2 Mines showing full signal etc.

  • Capn_Slow Tom Husband (@Capn_Slow) reported

    @O2 what is going on with your phone signal in East Somerset/West Wiltshire today? It’s keeps dropping out, worse than usual

  • AnnSewell15 Ann Sewell (@AnnSewell15) reported

    @O2 in New York and signal with mobile data is pathetic. Why am I paying for such a bad service

  • Ms_Cherry_B 🇬🇩 Elle-Ay 💕 (@Ms_Cherry_B) reported

    @O2 The call operators I have spoken to so far, during this debacle, have been BRILLIANT! But let’s be real, a payment system being effectively down since Tuesday, isn’t good form at all; do you want this money or not?!

  • tweetinglaurie Laurie (he/him) (@tweetinglaurie) reported

    @O2 Hello, I hope you're well. Please would you ask the powers that be if they could be less crap at fixing your phone masts and more proactive about flagging when they go down? Thanks
