    Recently moved back to @ThreeUK on a sim only plan and it’s blooming awful in terms of speed or coverage in central London. Thanks to my @O2 work E-sim I actually have signal!

  • SDuke46 Stegga (@SDuke46) reported

    @PaulSmithJnr @O2 It's awful. Same with Vodafone. Before I was 23 we never had mobile phones 📵 Life was cool.

  • cosykates 𝐾𝑎𝑡𝑒 • 🌙 (@cosykates) reported

    @O2 I woke up to check my order that morning and it changed from doing the delivery to out of stock so I called up and they told me to cancel my online order and try in store. Because there were no online orders available anymore even though mine was on the way already

  • _torijordan Tori Jordan (@_torijordan) reported

    @O2 anyone having problems with data from U.K. to Ire?

  • PenguinLoop Michael Johnson (@PenguinLoop) reported

    @O2 hi and sorry to trouble you. I pre-ordered the Pixel 6 Pro and you can claim some Bose headphones. Do I claim them via yourselves or Google?

  • Triplenath Nathan Woolley (@Triplenath) reported

    @O2 Managed to just tap my way through it. I assume it was just a little server issue. All sorted now though 👌

  • theburdtweets Kate (@theburdtweets) reported

    @Philbers @O2 @O2 is claiming it's a scam. But there is literally no way to contact them! Don't know how it's possible for them to access my account without me giving them any info? Absolute nightmare customer service from them.

  • northern_af Northern_AF (@northern_af) reported

    @O2 how do I get help from customer service when there is no way to contact you other than chat - which doesn't reply?

  • theburdtweets Kate (@theburdtweets) reported

    I had the weirdest phone call from @O2 customer service last night. Feels like the perfect example of how we are trapped in wasteful systems pushing us to buy more stuff all the time! 🧵👇🏻
