Latest outage, problems and issue reports in Carrickfergus and nearby locations:

  • 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).

  • Utter_Dil_Emma Mad Madame Em (@Utter_Dil_Emma) reported from Belfast, Northern Ireland

    I assume my bus home crashed and I died because hell is surely dealing with @O2 customer service chat for a ******* hour and a half.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

    @O2 you guys got a number to your payments team? I need to speak to someone. Automated IVR is poor.

  • EmGymMum Em (@EmGymMum) reported from Belfast, Northern Ireland

    @O2 @KLogan1977 Update: So @O2 asked me to DM details of the issue. I sent it hours ago, yet still no response. I wonder if there is an intention to help or it is an illusion of good customer service. Nor have I got promised call back after 22 hours from the CS phoneline. Not good!!

  • 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.

  • 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

  • salexander835 Stuart A (@salexander835) reported from Holywood, Northern Ireland

    @O2 I can't get logged into my account through the app or via the Web. Is there an issue?

  • leannereid1988 leane reid (@leannereid1988) reported from Castlereagh, Northern Ireland

    @O2 in o2 shop in newtownards the 3 fellas in the shop couldn't have bin any nicer and very helpful even when the problem was my own fault! Saved me a trip to Samsung! Def need a pay rise!! Thank you =)

  • Deadandgone70 Joel Ferguson (@Deadandgone70) reported from Newtownards, Northern Ireland

    Glad I’m leaving @O2. Trying to recycle my phone and according to CEX, TescoMobile and Game the small mark on my phone wouldn’t be a problem. But send my phone off and they say they’d give 50% of the value. Jokers like. Even in store they said it wouldn’t be a problem

  • 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!

  • 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.

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

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

  • StephenScarth Stephen Scarth (@StephenScarth) reported from Bangor, Northern Ireland

    @O2 Hi having problems making and receiving phone calls on a IPhone SE #O2

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

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

  • 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

  • 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 🙄

  • 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.

  • 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

  • Jay_McB Jason Brown (@Jay_McB) reported from Newtownabbey, Northern Ireland

    @virginmedia come on I have 4 Sims with VM. Even put something together online. Will @virgin customers be getting any rewards or paybacks like @O2 had to do when they kept getting network problems 😜

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

    @O2 AirPods and 🎅 is looking after them! Again fantastic service.

  • MrMatthewHolton Matthew Holton (@MrMatthewHolton) reported

    @JayClay71 @O2 Sadly not mate, there’s some issue within o2 with an iPhone / Apple Watch pairing, so will be sending both back tomorrow as I can’t use a device that isn’t fit for purpose ( no idea when it’ll be sorted ) so going back to and old sim only deal with my old phone

  • rs67_rs RS67 (@rs67_rs) reported

    @O2 Well that’s nice but why are your customer service agents saying 24-48 hours? That is what frustrates me. If they were honest and said what you are saying then I might not have tried to cancel the order. Why do things only start working when you are publicly criticised here?

  • Revenator Christopher Revell 🇬🇧 (@Revenator) reported

    @O2 and @SamsungUK need to improve there customer service. @O2, ordered a new contract but the phone has been delayed for unknown reason but the communication has been poor with no updates as to when I will receive the phone and you sent me a bill for a service I can't use.

  • codemonkey44 Ian (@codemonkey44) reported

    @O2 do you have some sort of service outage? My text messages have gone from blue to green and nothing I've tried has fixed it

  • AlexHill1872 Alexander Hill (@AlexHill1872) reported

    @O2 on an IPhone 12 Pro Max, I’m getting instant call failed when calling out and all incoming are showing as Unknown Caller, I’ve refreshed my network settings to no avail, Help!

  • SeeUnext2sday There is always Bismuth ☣️ (@SeeUnext2sday) reported

    @O2 Soooo the issues people are facing aren’t masts there are issues with many peoples phones today… unable to make calls/texts etc so get on it.

  • thingstobylikes Toby Isaacson (@thingstobylikes) reported

    @O2 Now my phone has no service.

  • SouffleGirl13 Souffle Girl (@SouffleGirl13) reported

    @O2 could you help? I need to recylce an old phone as part of my upgrade but no idea how😵‍💫

  • codemonkey44 Ian (@codemonkey44) reported

    @O2 Oh and trying to use my O2 App to start a chat with support just tells be to come back later because all agents are busy. Yet another reason to switch when my device plan ends in September

  • andytownuk andrew town (@andytownuk) reported

    @O2 provided PAC from previous network on order on Thurs, you said everything was set up yesterday. When should my number transfer? Or do I need to do anything else?
