    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

    @O2 I have also been doing this too. If this problem persists, then what?

  • Yvonnew25 Von (@Yvonnew25) reported

    @O2 Hi, I am having trouble with my iPhone. Any time I speak to someone the line is bad and there is a delay, checked coverage in my area and it says good - so perhaps it’s the phone? Switched it off/on! Had it less than a year - can someone pls help? Thanks.

  • jamesinyk Skinner (@jamesinyk) reported

    @O2 You miss the point. What are you doing proactively to block this crap? In the same way that Gmail dumps such nonsense straight into the spam folder.

  • davejackson16 Dave Jackson (@davejackson16) reported

    @O2 Thanks but I can’t call up as I have no signal
