    @itsthesd @O2 As if anyone is going to make sure they have a phone signal before making sure they have a roof over their head!! 🙄

    @O2 why is my 3G and 4G internet speed soooooo slow? Whenever have a powercut and loose WiFi it is impossible to use the iPhone even with 2 or 3 bars of network coverage!

  • RawBeard Märk Räwlings 🤘 (@RawBeard) reported

    After waiting 7 days for a replacement SIM from @O2 (fair enough it was delayed due to a bank holiday and a strike) it finally turned up today. Put it in my replacement iPhone… and nothing! After trying everything I can think off I finally contact O2 support. 1/3

  • SJamesAuthor Steph (@SJamesAuthor) reported

    It’s funny how @O2 @tescomobile and @virginmedia all say there is nothing wrong with the signal in my house, yet it drops constantly. Even tweets take a long time to be sent. I wish they’d just be honest and admit it’s crap in my area, than keep lying to my face.

  • ibrarqureshi Ibrar Qureshi (@ibrarqureshi) reported

    @O2 im totally without signal since yesterday (Saturday morning) While other family members on o2 have signal. Why is this?

  • mrslisaboyce Lisa Boyce (@mrslisaboyce) reported

    @O2 seems the only way to get assistance is to tweet you. The poor level of service is just shocking. #poorservice

    @Asunilrao @getpeid @O2 #nothingphone1 should resolve the phone heating issues , it's very uncomfortablr

    Hey @O2, turns out adblockers block your website content so I can't log in with a security code as it never appears. Should probably fix it.
