    @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?

  • 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

    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 😡

    @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?

    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

  • 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

    @tescomobile I was told customer complaints were going to call me yesterday after 13 days of calling you daily and over 10 hours of my time trying to get a resolution as to why my brand new mobile is not working. Not even your complaints department can be bothered to rectify ????

    Come on, @tescomobile, get your systems sorted, please. Tried to get a PAC code via text. Nothing. Tried your customer service who promised a text. Nothing. Was promised an email (checked my junk mail too). Nothing. What is going on?
