    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 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

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

  • 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?

  • 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?

    @emmapoulton13 @ThreeUK @tescomobile And they are on the O2 network which I'm on and mine was fine. Maybe your emergency notification settings are off?

  • chanandalabong Miss Chanandler Bong (@chanandalabong) reported

    @tescomobile Yes all compatible iPhones and yes, O2 removed a mast near by because of various issues. Used to have great 4G coverage but bugger all now.

  • marcgoodall1 Marc Goodall (@marcgoodall1) reported

    @tescomobile Experiencing ongoing trouble trying to log into my wife's account to upgrade mobile phone

  • radiodjdave dave smith radio dj (@radiodjdave) reported

    @tescomobile what is going on with your pay and go service topped up £20 and its eaten £10 in a day with only half hour browsing not happy

  • LeahHumphries21 Humphries BA (Hons) (@LeahHumphries21) reported

    @Calopumi @tescomobile Aww poor you. Mind didn't go off, and I'm on Tesco mobile... I am so happy. My partner...also Tesco went off

  • naffnaff85 Nathan Alexander (@naffnaff85) reported

    @tescomobile If it keeps going off I assume the only solution atm is to turn off in settings

  • finlay_mclellan Finlay McLellan 💙 (@finlay_mclellan) reported

    @ttb1965 @tescomobile Did your alert eventually come through? It's weird that the only person to get the alert in this house was my son's girlfriend who is on a different network provider.

  • ttb1965 TB (@ttb1965) reported

    @finlay_mclellan @tescomobile Yes it was 8 mins late, but the EE network was on time. Fair amount of people on here complaining to Tesco who have stock response that the mobile may not be compatible or emergency notice not enabled. Utter rubbish. Think their network needs sorting

  • CarolineCamero2 Caroline Cameron (@CarolineCamero2) reported

    Didn't get it either- emergency alert settings were on @tescomobile

  • mason151950 Ryan Mason (@mason151950) reported

    @tescomobile Awful service! No help at all. Says can't help me, Take my money and won't help me a vulnerable customer and won't do anything for me! ****** off.
