    So, @ThreeUK I realized that I must’ve made a mistake bc I didn’t get the verification email. So I’m like okay, let me see if I can reregister. Nope, it’s an endless loop. So I’m like, I need support. So I find the support page and ask to chat w/someone bc I hate the phone. Ok.

    @ThreeUK i do not know why your company still exist. The worst experience when it comes to using your pay as you go sim on vacation. Constant no signal in an urban above ground area. Even in a train station there is no signal. I would not tell ppl to use your service

    @ThreeUK Not in Greatstone where we get forgotten about about, I'd love it if you could put a 5g mast down here as would all of the locals, we are desperate for it.

  • DiegoM311 DiegoM311 (@DiegoM311) reported

    @ThreeUKSupport hi, having problems in M19 Post code with the broadband network, what is the problem and when it will get resolved? Thanks

  • Scarbygal Laura Baker (@Scarbygal) reported

    @ThreeUK I’ve just been to @Butlins in Skegness for the weekend and I’ve had no signal or data. I couldn’t use their Wi-Fi because I had no data to use to access the Wi-Fi. we’ll be back next year but if I can’t get a signal I may consider changing network. Our nephew had 5G

  • palmerio56 Eileen P (@palmerio56) reported

    @ThreeUK scammers are sending text messages saying there’s a problem with my direct debit, which is by untrue. Just be aware.

  • DaggettBrent brent.d. 🇺🇦 (@DaggettBrent) reported

    @ThreeUKSupport I can upgrade or leave in April and because of your more expensive pricing structure I actually looked at another network called ID mobile that's running on three and is basically using your old method for pricing and it's way cheaper with unlimited and a new phone!.

  • TheDudeAbidesxx Michael (@TheDudeAbidesxx) reported

    @ThreeUK your mobile internet speeds are ridiculously slow! Actually unusable. I'm switching to a different network today.

  • ThomasHaydenUK Thomas Hayden (@ThomasHaydenUK) reported

    @GorgonCity @ThreeUKSupport @ThreeUK 3. I had to be passed around so many times. Being told to call back tomorrow, or call a different number. They didn’t believe I told them to cancel it a year ago until I asked to speak with complaints department! Awful experience. Disgusting company.

  • p_crosland Peter 🏳️‍🌈🥶 (@p_crosland) reported

    @ThreeUK @ThreeUKSupport the signal at LA23 has been really poor all day, intermittently cutting out on my phone but my Three broadband hub literally will only connect for perhaps a minute every hour or so. Any idea when the signal will be fixed?
