    Does the @Huawei B535 support VoLTE? Your site says no. But with the AI Cube B900 supporting it, it wouldn't make sense for this new model not to. @ThreeUKSupport

  • NikiAlbon niki albon 🏳️‍🌈 (@NikiAlbon) reported

    the upload speed is consistently bad (3-5MBPS) and the download speed is FAST but cuts out whenever it’s being pushed (and by pushed, I mean video calls with more than one person.) I’ve spent most of February using my @ThreeUK hotspot. Praise be.

  • David201130 David (@David201130) reported

    @ThreeUKSupport Surely I should have been told it hadn’t been sent? As I was waiting for it. Unacceptable service for such a large organisation.

  • Halpin7 Alex Halpin (@Halpin7) reported

    @ThreeUKSupport Well I’ve only had the phone for a week now, haven’t always had the problems no I was with Vodafone before and worked fine there and at home. Have reset it a couple of times yes but no luck. Looks like it’s just a rubbish area for signal unfortunately.

  • PaigeEllis_ Paige El (@PaigeEllis_) reported

    @ThreeUK hi there I recently moved to three and used my PAC to keep my number, yday my number had transferred over but this afternoon it seems to have reverted back to the new number? Please can you help?

  • Halpin7 Alex Halpin (@Halpin7) reported

    @ThreeUKSupport Hiya, yeah the postcode for my works in CF11 8RR and my home is NP19 4DE I only ever had two bars of signal and always says 4G but takes forever to load anything and sometimes even says no connection. Thank you.

  • MaxdMerc 💥 Mᴀx’ᴅMᴇʀᴄ ❖ KodiNation💥 (@MaxdMerc) reported

    @ThreeUKSupport It’s just poor. A service shouldn’t get worse and worse surely? When I’m uploading files to my server it takes forever. If all this is normal, then maybe I need a new normal.

  • David201130 David (@David201130) reported

    @ThreeUKSupport I upgraded to the iPhone 12 and they said they would send a Sim. 2 sims had come and they said these won’t work as I want to keep the same number. Then was told a new 1 was on the way? Had to contact you guys again to be told there was a network issue and it hadn’t been sent?

  • ClareCjackson71 Clare Jackson (@ClareCjackson71) reported

    @ThreeUK Shite network. No 4g. Crap 3G. It’s amazing how my work phone on EE is excellent but the worst coverage and the customer service ever Over paying for a crap service. Can’t wait to leave in June.

    @ThreeUKSupport @ThreeUK please would you update/fix signal issues in DN4 0TB postal area because only getting 1 bar signal and H+ is shocking 😩😩😩😩😩
