    @O2 hi. My son’s sim has stopped working. He is part of my account (friends and family) and I’ve checked both and both are registered and paid. Can you help please?

  • MartinG04413826 Martin Green (@MartinG04413826) reported

    @O2 Anywhere would be good with me! Your network is ****.

  • smithie84 Liam Smith (@smithie84) reported

    @O2 received replacement E-sim from stolen phone, activated, however 24hrs+ later its still not receiving data. Have a 2nd PayAsYouGo sim with working 4G so its not a local issue. Any ideas?

  • Cumberdanes John Haswell (@Cumberdanes) reported

    @O2 When I go underground on the Metro. I’ll see folk using their phone with no problem yet the second I go underground nada. Also York, as soon as I step off the train in York I struggle to get a signal.

  • Place_of_Zen Place of Zen (@Place_of_Zen) reported

    @O2 what is the craic with your signal in Mid-Ulster? Why am I paying for this as it’s crap. Every single call I have made the past month has dropped, signal is never more than 1 bar. Total disgrace

  • martinmc81 martin mc (@martinmc81) reported

    @AJ_CELTIC @O2 Honestly 15 years with Vodafone never an issue, move to o2 they are horrific

  • Taylod61 ❌ David Taylor 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧❌ (@Taylod61) reported

    Once again @O2 4G network below 1Mbps or none at all. Bloody pathetic. Why can’t we have a network that has sufficient band width to Work. Or better still why don’t they get off the arses and roll out 5G? They don’t have a roll out program because you can’t find out about it.

  • michealewk96 Micheal Fitzpatrick (@michealewk96) reported

    @O2 No access to WiFi at work and one bar of cell reception which is useless and your telling me to connect to WiFi for calls that I pay a monthly contract for lol. I have never seen it so bad and I've had the contract 10 years or more seriously thinking about getting it cancelled
