    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 😡

  • 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

  • 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

    @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

    @tescomobile This handset refuses to send MMS despite your App showing I have plenty of data allowance left until my bill cycle renewal date. I'll share the screenshot by DM but ask you to confirm how this is possible and unrectified after 10 months of reported issues.

  • Moomalou Laura (@Moomalou) reported

    @lotttiiee @tescomobile There is an issue with a mast (near Raphaels Park I think). Hoping for a fix by 9pm.

  • bethanynoble_ Bethany (@bethanynoble_) reported

    @tescomobile sending me out an expired SIM card on my upgrade. Paying for a SIM card and a phone I cannot use. Cannot log into my remote access for work or anything. Only took 4 agents- x1 in store, x1 on the phone and x2 on the online chat to identify that I wasn’t the issue..👍🏻

  • Jodiescothern3 Jodie scothern (@Jodiescothern3) reported

    @WayneKillman @tescomobile Should be fix in from ilford had same problem

  • TheMKN10 MK (@TheMKN10) reported

    @tescomobile Sean when we call, the call disconnects as soon as we select option 1 for payg. The same things happens with the pay monthly option, so we don’t even get to the stage we can go to “all other enquiries”. Is there any other way we can get help please?
