    @maccaste14 @ThreeUKSupport I got exactly the same problem so it’s happening across the whole service

  • AGDun_162 Aldo (@AGDun_162) reported

    @robturp @rjbccj @ThreeUKSupport At present Three's 4G service, especially around EH6 7BY is little to non existent. You know there is an issue when switching to 3G, your speeds are much faster - on 4G Im lucky if I get 1.5Mbps Down & - Certainly not the service I am paying for - Despite complaining

    @ThreeUKSupport We have a mobile on three which is able to use mobile data in the house, might it be the case it is an issue with the specific router/broadband plan? Or are mobile data and broadband separate masts/connections?

    @ThreeUK is the biggest load of **** ever

  • callumbeattieuk Callum Beattie (@callumbeattieuk) reported

    @ThreeUKSupport In all honesty I tried to say my last goodbye to my family pet today and it let me down again. Sure you can understand my anger at Three. It’s not the sim I’ve always had same one. I lived abroad with no probs as three uses another networks signal. But back in UK it’s dire man.

  • ciannegcx Cianne Cass (@ciannegcx) reported

    @AppleSupport @ThreeUK my phone was working fine up until yesterday when @three made me reset my network settings since then my flash for alerts won’t work. It’s very frustrating as I had them in for a reason.

  • edscoeliacdiary Ed (@edscoeliacdiary) reported

    @glutenfreeginge @ThreeUK I’m very worried I’ll sign onto a new contact, move somewhere, and not have signal in my house!

  • glutenfreeginge Charlie👩🏻‍🦰 (@glutenfreeginge) reported

    @edscoeliacdiary @ThreeUK Im so disappointed with three recently too - never get service in my house
