  • ForbesProducer Forbes Coleman 🇬🇾🇬🇧🇪🇺 (@ForbesProducer) reported

    @ThreeUKSupport Here’s a few: B30 2SU B5 5SU B46 2QP Sometimes I can switch to 3G and just about get enough signal to load WAZE. But that’s not really good enough if I’m paying for 4G. So many times I have 2+ bars and NO connection.

  • ForbesProducer Forbes Coleman 🇬🇾🇬🇧🇪🇺 (@ForbesProducer) reported

    @ThreeUKSupport All over Birmingham. B1 up to B98 to the point I can’t get enough signal to use my satnav to get to my next drop

  • ABalharry62 AlisonB (@ABalharry62) reported

    @cazadams58 @ThreeUK Well was back onto them earlier today, the bloody robot then the Mumbai call centre, nice laddie don't blame him, but I'll try and call NYC soon and if it doesn't work I am done with them.

  • Datamitch Yes (@Datamitch) reported

    @ThreeUKSupport How come when I want to leave there is a problem getting my PAC code????? Chat cannot help. I wonder if this is a ploy to try and keep me? 🤔

  • chowdhury_faz Faz (@chowdhury_faz) reported

    @ThreeUKSupport Gave notice over the phone to cancel.

  • ForbesProducer Forbes Coleman 🇬🇾🇬🇧🇪🇺 (@ForbesProducer) reported

    @ThreeUKSupport When you say limited, what do you mean? Black spots? My home address is technically a strong signal area but I’m sat here on 1 bar 4G (using WiFi now, of course).

  • DBop86 Duncan Cheung (@DBop86) reported

    @ThreeUKSupport Hi Jonathan, yes, I get similar issues everywhere - Hampstead is a particular deadspot, but it's intermittent all over the country. The issue has been ongoing for perhaps the last 2 years or so? On both the iPhone X and now the 12 Pro.

  • hagger_zach Zach tatum-hagger (@hagger_zach) reported

    @ThreeUK your network in the last couple of months is a joke. Clearly oversubscribed and it can't handle the bandwidth. Think I may have to switch.

  • Keira_Kiwi Keira Lane (@Keira_Kiwi) reported

    @ThreeUK why dont you have a customer services email to send my complaint too chat and 8 million phone calls and still no compensation 👋

  • StephanieJaneS Stephanie (@StephanieJaneS) reported
