  • dominic_gunn dom (@dominic_gunn) reported

    @ThreeUKSupport Hey! My SIMs just gone bust, it’s not recognised on my phone (others are). It’s critically important that my number is functioning, I know I can order a replacement, but I’m wondering if you could instead help me switch to an eSIM to get me back immediately?

  • husnakhatri Husna (@husnakhatri) reported

    @ThreeUKSupport I have 5G home broadband but there are network issues. How long until those in the Enfield area are fixed? Having to come off wifi to watch videos in my own library on my iPhone is a bit ridiculous. I’m a new customer so wondering whether it’s even worth staying!

  • djalexgraham djalexgraham (@djalexgraham) reported

    @ThreeUK how do I speak with one of you agents! Customer service is a joke! Live chat just hangs Options on the IVR are pointless

  • TruthinTime2022 Truth Time (@TruthinTime2022) reported

    @ThreeUK I’ve just been out in the jungle in Thailand & on boats in the ocean & still had perfect 5G coverage on AIS. Yet it amazes me that I barely get a 3G network & only 4G (also barely) in Notts city centre. Do I need to find a new provider as your coverage is dire!?
