    @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

  • mind4sportpsych Dr Karen Howells (@mind4sportpsych) reported from Cardiff, Wales

    @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??

  • 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?

  • 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

  • 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

  • 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?

    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 went to Tesco Cradley to buy a mobile phone, I know the one I want, 5.54 pm and if your manger hadn’t been so rude or made it so obvious that he didn’t want to serve me I would have bought my Nokia 3.4 or whatever it is , very disappointed,customers don’t matter

    Thanks Maria @tescomobile you have sorted my issue after the network outage …. Why didn’t I think to reboot ?? Doh! Thanks

  • CarlMalkin6 Carl Malkin 💙 (@CarlMalkin6) reported

    Does anyone @tescomobile know what they are doing? It appears customer services hate customers and are intent on driving them all to other providers.

  • michaeltruefitt Michael Truefitt (@michaeltruefitt) reported from Loughborough, England

    @tescomobile Do you know of any network issues around Alton Towers (ST10) the last few days? All weekend I struggled to get any kind of signal and data working.

  • mpspencer180 Michael Spencer (@mpspencer180) reported

    @tescomobile is your Tescomobile app having issues. Nothing loading and saying there is an error. Deleted and reinstalled and now can’t get on at all?

  • Jerryturner262 Jerry Turner Esq 😜 (@Jerryturner262) reported

    @soltozac @tescomobile I'm having the same trouble. My 4G appears to be working, but I can't seem to make calls. Called my Mother on messenger and she can't make calls either. She's on @tescomobile as well. Not sure what's going on.

  • pinksazz78 UKEWLadyWarrior (@pinksazz78) reported

    @tescomobile hi my son and daughter are on your network and both have had same issues for past week, can't hear phones ringing and missed important appointments and if they call out they can't hear person on the other end, is this a technical problem?
