  • realirish The Irish starvation (@realirish) reported

    @GaelUlaidh Maybe it depends which network you use. But I know @O2 have serious data bandwidth issues in the centre of Derry. And their 5G speeds here are laughable.

  • dredMMAcrypto dredMMAcrypto (@dredMMAcrypto) reported

    @O2 what's up with the signal today? I've had no signal pretty much all day!

  • gsmudan Gurmeet Singh Mudan (@gsmudan) reported

    @O2 Please help with a problem with Volt-ons. It's impossible to get through to your online chat service and there appears to be no telephone number either.

  • declan_kidd Declan Kidd (@declan_kidd) reported

    @virginmedia @O2 Customer service?

  • UKPCTech Dave (@UKPCTech) reported

    @O2 Hi, I've been holding on the phone to customer service for ages to no avail. Are you able to assist with a minor billing issue please?

  • DrMiaow writer of strange software (@DrMiaow) reported

    @O2 HI, how do I please become a customer to get an eSIM? (Not a physical sim but an electronic one). I've tried navigating and finding how on your website and can't seem to figure out how.

  • ByTheirHalos Biscotti (@ByTheirHalos) reported

    @O2 4 weeks since I placed the order tomorrow and I have received no email about delivery. So it won't be here within the promised timescale. How do I cancel this bogus contract and get a refund of the money you've taken from me already, for a product you don't have

  • HoneyP26 Honey Price (@HoneyP26) reported

    @O2 Hi. My new 5G sim card seems not working on my new phone. How can I activate it? Is it the same number that I have before?

  • masonjandrews Mason (@masonjandrews) reported

    .@O2 @tescomobile recipients are reporting that my outgoing voice is incredibly quiet on phone calls, is this an issue on your end? thanks.

  • PhilActon Philip Acton (@PhilActon) reported

    @O2 Old SIM still has service. Followed the instructions from your link to call 202 but twice got kicked off referring me to the My 02 app! Had to say that my call was "urgent or complex" just to enter a queue that I'm still in.
