    Hey @O2 I’m abroad and my data roaming speeds are almost unusable! 0.3 Mb/s down on 5G! How do I go about getting the throttling removed?

    @O2 and @tescomobile What is happening with the phone signal in Cheshire??? It's dropping out all the time!! It's ridiculous!!

    @O2 is the worst network in the UK pass it on

  • griffsr Scott GriffithsClare (@griffsr) reported

    @O2 very disappointed that had no signal or data at Fairford for the last week. I was told that O2 refused to put extra support in the area due to the air tattoo which is what normally happens. EE provided this for their customers so not sure why you didn’t? Time to change to EE

  • hyaweh2002 Herbert Yaweh (@hyaweh2002) reported

    @O2 the customer service is really bad , I have spent 2 hours on the phone with customer service to sort my WiFi out

  • LaneCGree Lorraine Green (@LaneCGree) reported

    @O2 I have been left shocked by the fact after I left O2 and got my pac code. Your team have decided to disconnected MY SONS number (which is on an ongoing contract with no issues) and try and charge me over £600 during a cost of living crisis! 11 yo with no way to contact family

  • sean_deeks Séan Deeks ⚕️ (@sean_deeks) reported
