    @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

  • 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?

  • 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 😡

  • 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

    Does anyone have ridiculously poor internet speeds with @tescomobile? It’s literally painful to perform any task that requires data.

  • janiec21 jane clift (@janiec21) reported

    @tescomobile is there a problem with yr network?

  • theboydonald Theboydonald (@theboydonald) reported

    @tescomobile @WhichUK Yeah right! Any of us wondering when we might get mobile data due to “ongoing issues” with our PAC code transfers ( 2 weeks, 5 calls,2 hours) might disagree.

  • GregorThomas2 Gregor Thomas (@GregorThomas2) reported

    @tescomobile @WhichUK Shocking considering I am unable to use mobile data. So effectively paying loads just for calls and texts. Not good service

  • DawnLou_S Louise0901 (@DawnLou_S) reported

    @tescomobile @WhichUK @tescomobile I logged a complaint 2 weeks ago and still have not had a call to resolve. Numerous calls have been made to your customer service department promises of calls to be returned which have never been fulfilled. I am absolutely shocked of the delivery of your service!

  • manutdTOPFAN73 Joneschris (@manutdTOPFAN73) reported
