    @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.

    @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€

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @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?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

    @O2 can you please reply to my dm, I'd like to get the issues I have with my order resolved asap

  • Abhi_Times Abhijeet Ahluwalia (@Abhi_Times) reported

    @O2 Yup 😢 Moved sim to other devices and same issue. Put other sim into my device and it worked immediately. So it's not my device. Rang customer service, they say 'wait 24 hrs, then we'll see'. Sceptical tbh, never had to wait to get imessage working on other switches, why now?

  • NicoleMCFC Nicole ☀️ (@NicoleMCFC) reported

    @O2 Hi, I’ve seen a better deal with another network provider which is cheaper. I haven’t got long left to pay on my current contract. How would I go about transferring my mobile number to this network?

  • nikgpanag Nick PANAGIOTIDIS (@nikgpanag) reported

    Big shout out to the tech support behind @O2 twitter feed, if only 202 call centre could've delivered this without a need for 35DM. Solved at last 🙄

  • Louise_28x Louise Martin (@Louise_28x) reported

    Had no signal for over a week now and missing important phone calls with no reply from o2 on online chats 🙈 what's going on @O2

  • FunkadelicHorse Binyizdabbalah (@FunkadelicHorse) reported

    Hey, @O2, is it your policy - on top of having literally the worst customer website in the inner solar system - just to never answer emails? Did you think you'd hidden the email portal so well that no-one would ever be able to send you one?

  • elvesnfairies elfie (@elvesnfairies) reported

    @O2 I’ve been trying to get my PAC code the last week. 1st was told it’ll be email to me, but never received email. Call few times, either your call centre person was unable to give it over the phone or hung up on me. What’s going on??!!

  • TamMcGuiree TamMcGuire (@TamMcGuiree) reported

    @O2 must have the worst internet out ! Cant get a connection anywhere !!

  • TheCountess5790 _𝕿𝖍𝖊 𝕮𝖔𝖚𝖓𝖙𝖊𝖘𝖘_ (@TheCountess5790) reported

    @O2 pretty poor show that I make an order on the premise that I will be able to collect my new phone today, then I immediately get a text to say I can’t and you don’t know when I will. I’ve spoken to someone about it from one of your call centres who was just reeling off script…

  • TVPaulD Paul Douglas, Videographer 💙 (@TVPaulD) reported

    @O2 I had an upgrade transaction for my Apple Watch fail at the end for some reason on Friday. I'd like to try again, but not while the Upgrade Fee is still a pending transaction on my account. It's still there now, how long do you take to release these?
