  • 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?

  • 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

  • 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?

    @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?

  • 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

    Can anyone help, having real issues with @tescomobile since changing provider, who do I contact to escalate???? @vicderbyshire

  • paulhicksuk Paul Hicks (@paulhicksuk) reported

    Another day of total ineptitude @tescomobile . That’s an entire week now since you said you were transferring my number. Instead I have had no calls for a week. You can’t even tell me when it will get solved. Incredibly poor customer experience.

  • GrimeyDubya Graeme (@GrimeyDubya) reported

    @tescomobile it’s now 9 days of not being able to change my safety buffer. Surely it can’t be difficult to get your tech team to “debug” it to find the issue. Come on guys , ombudsman getting copied next .

  • PJMC1986 Phil Canavan (@PJMC1986) reported

    @O2 hi if I have an iphone on TescoMobile which uses o2 network, can I buy an apple watch from o2 site? Thanks.

  • CheesyPeasAgain Ed English (@CheesyPeasAgain) reported

    @tescomobile I have been having problems since November, this will be my 4th SIM card. She promises me this one will work. Yes this is being sent when I reported I was unable to get calls or phone anyone.

  • Eric_Phenix1992 Eric Phenix (@Eric_Phenix1992) reported

  • ZeeHabib1 Zashan (@ZeeHabib1) reported

    @tescomobile - why am I getting letters from a debt collector, my phone was paid in full and my 30 rolling contract was cancelled with all payments paid as confirmed by your customer service (I have written confirmation) sort it out.

  • PamSSaunders Pamela Saunders (@PamSSaunders) reported

    @tescomobile Hi Chris. Still not able to receive or make calls. I am hoping the SIM card arrives today. If not I will get back in contact. Thanks for your help.
