    @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 My phone has had no signal for phone calls and texts over the last 3 hours... Is there an outage in North London?

  • DiLussoMenswear dilussoclothinguk (@DiLussoMenswear) reported

    @ThatManIsBack @O2 @stojoco We jus want a network that works not free coffee cups 😫

  • Phaceless_Photo Phaceless Photographer® (@Phaceless_Photo) reported

    @ritamoraruk @O2 That’s probably a SIM card issue

  • NickyThomas Nicky Thomas (@NickyThomas) reported

    @O2 Despite even speaking with a customer rep on the phone, I told them what the issue was and they reassured me they would pass the message on and make sure your 'service' centre looks into it properly. Clearly, they can't read either?

  • pickled_tinker Ian Grody (@pickled_tinker) reported

    Such a shame that some customer services agents at @O2 bend over backwards and are more compassionate than the company they work for. I've had nothing but shoddy performance from this network from day 1. Your staff deserve more. Your services suck and your staff bare the brunt.

  • BarryStump BarryStump (@BarryStump) reported

    @O2 you are still sending me text messages that my bill is ready when i moved my number to BT 3 months ago Are your staff on some kind of medication? or just stupid?
