  • stephenblevins9 Stephen Blevins (@stephenblevins9) reported from Rich Hill, Northern Ireland

    Could someone at @O2 explain why the service in BT61 has been diabolical for almost two weeks? Bit of a nerve advising us of a spike in bills alongside a drop in service? Not exactly sure what I’m paying for at the minute.

    I have an @O2 Samsung phone. I leave it on mobile data and WiFi all the time. If I am not in a WiFi area then I struggle to do anything on the phone. It has always been this way. Why is this? Is the @O2 network just bloody shite? 🤔🤬

  • Sean_O_Tron Sean 3D (@Sean_O_Tron) reported

    Wish I could turn off 5G on my phone. Not because I believe in any of the conspiracys, it's just crap and way slower than my 4G was. @O2

  • ThinkingOfStew Stewart wallace (@ThinkingOfStew) reported

    @O2 my phone is not working, it's still under the device plan. Is there anything you can do?

  • charlottemegann Charlotte (@charlottemegann) reported

    @O2 hi, I have had no phone signal since last night. I'm in RH16 and normally the signal is fine; it says on your website that a "mast isn't working as it should", is anything being done to rectify this?
