    @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?

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @O2 hi currently abroad and suddenly have no service ??

  • RachT234 RachT234 (@RachT234) reported

    I’ve since moved to @O2, who responded helpfully, respectfully, and actually listened — even when I had no service and had to rely on a family member’s phone (without Relay UK, and with encouragement). This outage was caused by Three failing to provide porting info, leaving me without service for around 10 hours. In contrast, Three left me feeling ignored.

    @O2 what the hell is going on? Full 4G signal and can barely refresh my Twitter let alone watch the F1 qualifying.

  • Unofficial_Phil Phil (@Unofficial_Phil) reported

    @O2 ran out of data - didn’t receive a warning, couldn’t check my allowance. Had to spend £5 to connect to EE WiFi just to see my account. Awful service
