    Hi @ThreeUKSupport I recently joined you with the 4G Huawei router. On the 14th day (last day to cancel) I had no internet but was fine on my 3 Phone so not a signal issue. But I got it working again. Now just had the same happen. What is wrong with this router?

    @ThreeUKSupport Hi Myself, my girlfriend and my mother are all having an issue where are numbers are not being recognised for a call, never connecting and can't call on a landline. We're all on 3 on separate contracts and all paid up. Is there an outage going on?

  • danfairless97 Dan💙 (@danfairless97) reported

    @ThreeUKSupport are the worst. Waiting 5 days for a phone they said would be here on Wednesday, then told me it’ll be here Thursday. Then told me it’ll be here today. Instead of lying to your customers just actually tell them the truth

    @ThreeUKSupport why ******** am I paying £80 a month for my internet not to work and my texts not to send 😒

  • mrsbadge22 Kirsty Barnett (@mrsbadge22) reported

    @ThreeUK once again no 4g coverage = no internet = no working from home & home school problems. 3rd time this week! Not good enough 😡😡😡😡😡

  • JonSykes2203 Jon Sykes (@JonSykes2203) reported

    So @ThreeUKSupport it appears it's all your fault. It seems you needed to re-register the email account I have been using for years and which your system quite happily sent reset emails to. Emails that would never work. And which generated the useless error message. Wankers.

  • archefluxx Archefluxx (@archefluxx) reported

    The fact that @ThreeUK don't have any S20 FE phones in the UK until the 28th January is making me wonder if they're the best network for me.

  • BaldTrooper BaldTrooper (@BaldTrooper) reported

    @ThreeUKSupport which number is for complaints please? Its been 37 hours with no signal because my sim card has been turned off I have no Internet texts or calls & been told this is normal & to wait for new sim It's never happened with any other upgrade I've had.
