  • HAndTheElements Hegsy & The Elements (@HAndTheElements) reported from Cardiff, Wales

    @tescomobile what is the escalation process regarding a faulty phone that has been lost by @Tesco? My OAP mother has been without a phone since September and promises to resolve have failed. No senior support from Pengam Green Management or in-store guidance. #disgracefulservice

  • soozles_ Soozles (@soozles_) reported from Barry, Wales

    Seriously getting sick of the awful signal from @tescomobile 4 years I’ve been a customer and have 4 contracts with you spending &150-£160 a month and it’s getting worse everyday! Been trying to speak to someone all day (friend) and constantly getting call failed 😡

  • soozles_ Soozles 🏴󠁧󠁢󠁷󠁬󠁳󠁿💙 (@soozles_) reported from Barry, Wales

    @tescomobile I can’t call or receive calls today, get call fail on them all but I’m able to text and use data without a problem. Is there a problem in the CF63 area?

  • TRHComposer Thomas Richard (@TRHComposer) reported from Cardiff, Wales

    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

  • RachelKendall16 Rachel Kendall (@RachelKendall16) reported from Risca, Wales

    @tescomobile Hi, can you tell me if Tesco intends to support Apple Watches any time soon on a cellular level. If not why? O2 network is used on Tesco mobile…. How far apart can an iPhone be away from a watch if used and will your Apple Watch connect to all available WiFi?

  • nigelbendybus Nigel Smith (@nigelbendybus) reported from Cardiff, Wales

    Thank you so much @tescomobile for sorting out and reimbursing me for the scam texts I received yesterday. Yet again wonderful customer service from @tescomobile

  • jonmuggle Jon (@jonmuggle) reported

    @tescomobile No 4G/Wi-fi calling and signal ain’t no where near as good as EE. If it doesn’t change bt the end of my contract then I won’t be renewing

  • LaurenSatsuma 🎃Spooky Lauren🎃 (@LaurenSatsuma) reported

    @tescomobile I've always been a Tesco mobile customer so I didn't actually realise other networks were doing this. Yikes.

  • gemmih83 𝓖𝓮𝓶𝓶𝓪 𝓗 🎗 (@gemmih83) reported

    @tescomobile @VodafoneUK - is there any way I can get my contract down in price? I also think when I got my tablet you restarted my phone contract as when I went into a shop the date they told me was totally wrong.

  • briishbloke2407 Sussius Amogus (@briishbloke2407) reported

    @tescomobile Giffgaff has never hiked up my prices. I've been paying sod all for 40gigs of data for years now.

  • ChowdryGwenn Gwenn Chowdry (@ChowdryGwenn) reported

    @KetamineMr @guinesschugger2 @tescomobile Evidently not, I was once in a store and the manager came up to me dressed as a rabbit and made me pay them £100 or they’d shoot me. See how easy it is to write words down.

  • KetamineMr MrKetamine (@KetamineMr) reported

    @CraftyGirl72 @tescomobile As someone who works for a phone company I can say it's probably not tescos fault but what's in your house is a signal blocker, things like the insulation, types of windows thickness of walls etc. If it worked outside then it's more likely the house.

  • MikeSimulation Mike Simulation (@MikeSimulation) reported

    @cruzcooper647 @JacobSully6 @tescomobile I'm paying £10 for 4GB with Tesco. Honestly, am very happy with the price given that the network around London is very reliable and fast (I also don't use much data).

  • NotKingLiam Liam☔🌹 (@NotKingLiam) reported

    @tescomobile Lol @ThreeUK increasing my contract nearly every 6 months overall by £12 at the end where we couldn't cancel for 2 months because they kept taking money out my account after I'd cancelled and wanted to go pay as you go

  • SwarveStudios SwarveStudios (@SwarveStudios) reported

    @AEWMike @tescomobile @EE Bruh EE is the biggest scam.. They say they have the most 4g coverage, theyre not lying, but theyre not telling you whether the quality of that coverage is good. So many areas it will say 4g but you'll have no signal so its a massive loophole and marketing ploy with kevin bacon

  • porcinesludge hello human (@porcinesludge) reported

    @chris_carley @dazzypops @tescomobile I could never do that, my mobile signal to my house is terrible, no-one that I choose helps, I'd love to be able to use unlimited data through my phone
