    @ThreeUKSupport @ThreeUKSupport is that humour? The issue existed for months prior to me talking to the 'team' - my image of PM was from back April this year and it has persisted until today, so 7 months have passed since being "passed on" - how was tweeting you of any help whatsoever!?

  • TraceyMcEachran Curious cat (she/her) (@TraceyMcEachran) reported

    @ThreeUK please can you tell me why the network is so slow, I'm in Havant but the network has been so slow everywhere lately even on 4G

  • AndyJents Andy J (@AndyJents) reported

    @lloydhollett @ThreeUK @O2 Sorry Lloyd but #3Mobile use the same network as #o2. Hopefully the customer service will be better though!

  • robinaled Robin Davies (@robinaled) reported

    @ThreeUK Good morning, signal is non-existent after work last week, Just renewed a contract and added another which are now completely hopeless as there’s no signal. Can you please look into it for me! Thank you. Postcode LL151UT

  • Gxest Arran (@Gxest) reported

    @ThreeUKSupport had no signal in Eastbourne since the 5G masts have been put up. Is this being sorted and do you know about it?

  • robyn_clewsX robynpaige✨ (@robyn_clewsX) reported

    @ThreeUKSupport is there a problem with your services? My internet was fine all morning and now nothing can connect to the internet?..

  • hutson_nigel Nigel Hutson 💙 (@hutson_nigel) reported

    @rob3047 @ThreeUK I had a 3 SIM for the iNet unit which wouldn’t work. I contacted @TrumaUK and they asked if I was using a 3 SIM. They didn’t know why, but they just wouldn’t work. Whether they’ve resolved it I don’t know. Changed SIM and never had an issue since.

  • WestieMum01 SEB (@WestieMum01) reported

    @MrBrooksOnTour @rob3047 @ThreeUK Troutbeck Head is virtually non existent signal, Meathop Fell was fine on EE. Club Site WiFi is not keeping up with newer systems. 5G, as 8 found out last week at Crystal Palace is very fast indeed.

  • DR_McViz Dr McViz (@DR_McViz) reported

    @ThreeUK Network completely down in G33 6 area following a mass power cut. No facility to report it on your website!!!
