    Anyone from @ThreeUK I can ask a quick thing? Live Chat didn't solve my problem.

  • Tiny_Legs Amy Lafont (@Tiny_Legs) reported

    @ThreeUKSupport I have a PIN. The issue is that the phone number doesn’t even connect - the message I get is that it isn’t a valid phone number.

  • zgb210194 Zee Bee (@zgb210194) reported

    @ThreeUK Can I just say how poor your signal coverage is in this country ? Might as well send a message with a pigeon it would get there quicker #inadequate

  • LReed2021 Shiba2themoon (@LReed2021) reported

    @ThreeUK The service I received so far has been shocking. No conformation emails of my new order, which is for my girls birthday on Monday. Call centres keep tell me same stuff for 3 days, all approved OK, upfront payment accepted. Just waiting on handset. Please contact me

  • LReed2021 Shiba2themoon (@LReed2021) reported

    @ThreeUK I really need this sorted as you have my money all checks have passed yet still nothing emailed to confirm and nothing dispatched. Please help !!! I can even collect from a store, I just don't want my little girl waking on her birthday and her main gift isn't here.

  • DuvaldoA10 Duval Akonor (@DuvaldoA10) reported

    @ThreeUK when are Three going to allow e-Sim in the network. I have a Galaxy Watch 4 and can't use it without my phone. O2, EE and Vodafone all offer this. Will I have to join them? 😕

  • cjwhittle Chris Whittle (@cjwhittle) reported from Stockport, England

    Ever since the “improvement” works in the area, my signal has been terrible @ThreeUK The internet is barely functional which is very annoying as I used to rely on that daily when our Sky Broadband inevitably crashed

  • Cameralabs Gordon Laing (@Cameralabs) reported

    @PhilErmiya @ThreeUKSupport Thanks for your suggestions - it says SIM not recognised when I insert any of my Three UK SIMs, even though they work on other handsets - and they also worked on the 4a previously. Problem is regardless of location too. I'm suspecting maybe an Android update or a faulty SIM slot

  • Neatamos Anita 💙 (@Neatamos) reported

    @ThreeUK my daughter has been without a phone for over 2 weeks as she is waiting for confirmation from you to repair her phone! Terrible service and putting her in danger with no device do make emergency calls if she needed to
