  • 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?

  • 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?

  • 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

  • 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

  • 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?

  • AidanLewis23 Aidan (@AidanLewis23) reported

    @tescomobile upgraded contract, 14 hours later tesco cancelled it and sold my phone to some one else. Admitted it was their error and that 3 separate people had made errors handling my upgrade…solution “nothing we can do about it just wait and see if it comes back in stock”

  • AidanLewis23 Aidan (@AidanLewis23) reported

    @tescomobile I’ve just been on the phone an hour trying to sort this. This is yet again a new complaint based on your service

  • JennyAKoenig Jenny Koenig (@JennyAKoenig) reported

    @tescomobile can you explain please why my phone won't connect to a network in Sydney Australia. It found a network in Singapore as soon as I arrived there but in Sydney I just get "emergency calls only" any ideas?

  • SDreams107 Mick .xrp I’m pre-rich 😀 (@SDreams107) reported

    @tescomobile If I got my dream phone , it’d be useless on your network as it never has service for more than a few days at a time. I never had issues with Vodafone like I do with @tescomobile .

  • kencoco14 kencoco (@kencoco14) reported

    @tescomobile It’s near enough 2/3 times a week the service drops it’s awful

  • reddeath614 Robin (@reddeath614) reported

    @tescomobile It's been like this ever since I moved here in 2019, across 3 different phones. It works completely fine elsewhere. My phone shows as having a signal but I can't send/receive calls/texts and don't get any internet. Even outside.

  • SDreams107 Mick .xrp I’m pre-rich 😀 (@SDreams107) reported

    @tescomobile Lol, which storm is it currently? We’ve had no service for almost a week.

  • GalloUK13 Gina Gallo (@GalloUK13) reported

    @tescomobile I am trying to connect with someone to get my upgrade. Please help me

  • shanes_loonie leah the loonie :)💚🧡 I miss my pops 💔 4.12.20 (@shanes_loonie) reported

    @tescomobile £13 a month with 60gb of data thought I was onto something until I realised the coverage checker lied to me and I got a crap signal

  • andy_rivs Andy Rivers (@andy_rivs) reported

    @tescomobile @BBCTheOneShow I got a 2nd sim in march, as it was on a different date to my monthly bill you've started charging me twice a month for both phones and your customer service reps seem unable to grasp that this is wrong. I would like it sorted please or you're about to lose a long term customer.
