  • Saeed_Ahmed02 Saeed Ahmed (@Saeed_Ahmed02) reported from Victoria, Wales

    @tescomobile needs to better support the Google Messages app. I quite like using the Google Assistant to send texts and it always comes back saying failed

  • 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

  • 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?

  • 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?

  • 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

  • mikeymctavish Mikey Rae (@mikeymctavish) reported

    @tescomobile Not all the time but can be pretty bad even though it looks like I should have reception

  • wantanswres Wantanswres (@wantanswres) reported

    @tescomobile your systems were down yesterday & I was told my price would be honoured & it’s not!! What is going on with lying to customers & then can’t get through on the phone!!!!!!!!!

  • Richperks 𝗥𝗶𝗰𝗵 𝗣𝗲𝗿𝗸𝘀 (@Richperks) reported

    @tescomobile I’ve tried in two other phones; same problem I’m afraid. Does this suggest the sim is faulty?

  • Lillyjconley2 Lisa Conley (@Lillyjconley2) reported

    @tescomobile 5 days after porting my number to TM still no signal. TM helpline says systems down. Instant Messaging stopped helping mid conversation. Please resolve!

  • Spb20Sp SPB17 (@Spb20Sp) reported

    @tescomobile how do I cancel my contract with you?

  • Wayneyboy85 Wayne Kinder (@Wayneyboy85) reported

    @tescomobile Absolutely appalled I've had no working SIM for 3 days now and customer support aren't helpful! Have to walk to town to use free WiFi every day! SIM was sent Monday but you cut my old SIM off Tuesday! Where's the logic in that?

  • cwalbone Corey Albone (@cwalbone) reported

    @talkSPORT @tescomobile For all the criticism I genuinely believe that coming back from a bad injury that he played on to a UCL final with 3 years ago has been followed by never rly having a consistent run of games at spurs or everton Still shows flashes of quality but needs more than 1 start a month

  • pyscho_penguin Sarra (@pyscho_penguin) reported

    @Fredrob10 @tescomobile Well I can use Wi-Fi calling on mine no problems

  • donna70352225 donna (@donna70352225) reported

    @tescomobile The call back was meant to come Wednesday around 11am which never came. I very disappointed im not getting a good service since I have been a customer for yrs. now the deal I wanted has ended.
