  • 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

  • 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?

  • 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

    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 😡

  • 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??

  • 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?

  • 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

    @tescomobile I haven't tried putting it back, had the new phone 2 days and I am not happy! Was working perfectly, hardly getting any signal have to use wi-fi.

  • stephen34047269 stephen kay (@stephen34047269) reported

    @tescomobile I don’t trust Tesco and I would never buy a mobile phone from them even if it was free

  • dunstablian John (@dunstablian) reported

    @tescomobile Is your website down ?

  • Deborah2000__ Deborah (@Deborah2000__) reported

    @tescomobile Bad company, and always have been. Surprised the different prices (massively inflated) for people without a club card is actually legal. Tesco’s always up to some con job.

  • LizardfromDraco Suburban space thing (@LizardfromDraco) reported

    Hey @tescomobile my phone is going straight to voicemail and I'm missing calls. Can you help please?

  • MadMaksimiliyan Max Ripper Stim (@MadMaksimiliyan) reported

    @tescomobile Go **** yourself forcing me to use your **** clubcard, so that you can track my purchasing activity. When the markets crash I'll be shorting the hell out of $TSCO 🖕🖕🖕

  • BuryLass144 Christabel 🤓 (@BuryLass144) reported

    @tescomobile Tried TWICE to get in touch regarding my new Sony phone, gave up ! I transferred my SIM card, same size so no problem but my mobile data has gone from a fast 4G to a very slow H+ while in the house. I have tried reinstalling, restarting etc to no avail!

  • NolitaWerett Nolita Werrett (@NolitaWerett) reported

    @tescomobile No problem reported on that website but I am still unable to open the Tesco mobile app. I can't DM you because Twitter needs to send a confirmation code to my number and I am not able to receive SMS texts.

  • jangomac72 Jason McLaughlin (@jangomac72) reported

    .@tescomobile absolutely awful customer service this morning, trying to sort out my mothers new phone as she’s just joined your company and 3 times been cut off by agents, waited a total of 97 mins on your CS line, not very impressed!!

  • NolitaWerett Nolita Werrett (@NolitaWerett) reported

    @tescomobile is there a problem with your network? Message on my phone says emergency calls only.
