    @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

    @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?

  • 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 😡

    @tescomobile I tried, and it wouldn’t work as I have no access to the phone. The person was very unhelpful. I just managed to do it as a guest. No help, the mobile is in a care home, and we have no access to this. And nursing staff text my personal number when it needs topped up

  • gembob86 Gemma (@gembob86) reported

    @tescomobile I'm having huge problems trying to redeem my code for free 6 month subscription to club card plus. Contacted you last week via website but still haven't received any help :(

  • VanessaA216 Vanessa.A.21 (@VanessaA216) reported

    @tescomobile is the network down? My phone has no signal and keeps saying "not registered on network" when I try to make a call. I have removed the sim card and put it back into the device but it's still not working

  • mediate4ueu mediate4u (@mediate4ueu) reported

    @tescomobile Why do you support Israel?

  • cdm131 Carol Newsham (@cdm131) reported

    @tescomobile I am trying to initiate the offer for 6 months Clubcard offer for my new phone. The phone is in my name but OUR Tesco account is in my husband’s name, is this causing it to fail? Offer runs out tomorrow so am panicking a bit now

    @HMRCcustomers @beckbrady75 I've had 5 in 2 days! Sick of it! Blocked and reported each time but they use a different number. Can't the phone networks shut this down? @tescomobile ?
