    @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?

    @tescomobile I have not had a signal for 3 days now. I’ve been told that there is maintenance work being done on a local mast, but even when I move 30 mins away from home then I still don’t have a signal. What is happening??

  • 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 @StanAHill He's not the only one feeling this way. Please check the nenthead noticeboard on facebook, there are multiple threads of loads of people having the same issue. We have reported pretty much every day, and seem to be getting fobbed off too.

  • Kona_Tat Kona (Gamer's Inn) (@Kona_Tat) reported

    @Kitutal @tescomobile Tesco mobile is pure crap, I spent every month last year trying to fight them to pay my bill and always got charged for their mistakes... The same with @virginmedia lately.

  • official_jle JamesLE 🅙 (@official_jle) reported

    @tescomobile @tescomobile 2/2 and that it’s going to be sorted soon but it’s beyond s joke now. For the money I pay for my tariff I should expect a half decent coverage. I was sold the contract as “Use the O2 network and it’s the best coverage”and for a period of time it was. Now not so much.
