  • 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?

  • 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?

  • 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

  • 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

  • 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

  • dannyjamesjohn Danny (@dannyjamesjohn) reported

    @tescomobile is the network down in Gloucestershire?? Can't make or receive calls

  • Matth3wR0berts Matthew Roberts (@Matth3wR0berts) reported

    @tescomobile Used the link you provided. Told me@it sometimes gets busy and I should use Wi-Fi, I clearly stated I couldn’t make or receive calls! My partner is also on Tesco mobile and hers is fine. If my signal could be turned back on that would be good

  • KrispymooScott Kristy Scott (@KrispymooScott) reported

    @tescomobile You need to stop with automated responses. My last message was in response to this message. This link states there's no problem in my area - this should have been updated to show the concern after 5 hours has passed, don't you think??

  • amccann06 Amanda Bruce (@amccann06) reported

    @tescomobile any idea when your signal will be restored? ML2 area

  • AlTaylo50969962 AlTaylor (@AlTaylo50969962) reported

    @tescomobile DY2 and parts of Birmingham are not working. No calls in or out.

  • lewisgonzo1987 Lewis Williams (@lewisgonzo1987) reported

    @tescomobile are we going to get an answer at all, as too why we can’t make or receive calls?? Think this is more then just a little glitch. Please do not tell me to check O2 website as that just says no issues in your area. Surely you should know by now what’s causing this

  • lewisgonzo1987 Lewis Williams (@lewisgonzo1987) reported

    @tescomobile Any issues may not show straight away??? It’s been like this since lunchtime, so 4 hours ain’t enough time to show up on O2 website?? Great customer service.

  • ChrisLoftus12 Chris Loftus (@ChrisLoftus12) reported

    @tescomobile hi is there a problem with your network as I cannot make any outgoing calls or receive any calls

  • lewisgonzo1987 Lewis Williams (@lewisgonzo1987) reported

    @tescomobile So that’s it?? Just a sorry?? Not being told anything by Tesco or 02. Paying for service which I’m not receiving. Happy to take peoples money but I bet no one gets compensation for this. Absolutely disgusting.

  • Doglef_ Doglef (@Doglef_) reported

    @tescomobile has been down pretty much all day! Sad times. Haven’t been able to make any calls 🥲 #network #down
