    @ThreeUK I’m travelling to Vietnam and noticed it’s one of your Go Roam Abroad destinations. As a Pay As You Go customer, if I buy an Add On, would there be any additional charges if I were to use data during my time in Vietnam?

  • StevenWainfur Steven wainfur (@StevenWainfur) reported

    @ThreeUKSupport wondering if anyone can help me out with unlocking my phone to any sim? I’ve been trying for 2 months now with 3 and no joy, seems an impossible task!

  • Hannah_Maryse Hannah (@Hannah_Maryse) reported

    @ThreeUK As far as I can see you charged me 35 quid for 3 minutes of roaming as I disembarked an aeroplane. Also, none of your support chat links works. Could someone please help me understand this mad charge?

    @ThreeUKSupport Weston, Spalding. To be fair signal pretty much rubbish almost everywhere

  • Arcee_TillAllr1 JMRichardson 🇩🇪🇮🇹🇺🇸🇬🇧🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@Arcee_TillAllr1) reported

    @ThreeUKSupport why is it always such a pain to get an old number transferred to you? Every time I renew my contract or take out a new one, it's never straight forward to keep my number. It's getting very tiresome.

    @ThreeUK Data use in the Midlands has been useless over the past few weeks. Birmingham City Centre and can’t find timed of trains. Pretty pathetic really. B’ham airport, no workable signal. 😡

  • Marooned_Sailor Ian Judd (@Marooned_Sailor) reported

    @O2 @VodafoneUK @ThreeUK if I bought a US iphone14 when travelling in the US can you support the eSim plan needed here in the UK?

  • Ste_Rumbelow Ste Rumbelow (@Ste_Rumbelow) reported

    @ThreeUK Please help! Somehow I’m using a lot of data abroad even though I’m only really sending messages. I’m close to the 12gb cap and have a few days left. Will the short term unlimited data package allow me to use more than the 12gb fair usage? Thanks
