    @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

  • 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

  • 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

    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 😡

  • 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?

  • Lou_M_Young louise young (@Lou_M_Young) reported

    @tescomobile I’ve lost my phone can you help and freeze the sim or something?

  • Jonnashiel Jonathan Shiel (@Jonnashiel) reported

    @tescomobile Terrible service from you - daughter transferred over to your service recently- now cannot get any 4g - she is currently travelling through Europe and can’t access her mobile data - pretty useless service from Tesco mobile - avoid them if you can

  • PeterIbitoye2 Peter Ibitoye (@PeterIbitoye2) reported

    @tescomobile why is my roaming not working in Portugal

  • MrsHoopDiddy Mrs Hoop Diddy (@MrsHoopDiddy) reported

    @tescomobile ordered a sim on 7th June and haven’t had it yet! My current contract ends on Saturday so I’ll be phoneless unless I get it! Can you help?

  • aimhdesigns 𝖆𝖑𝖑 𝖎𝖓 𝖒𝖞 𝖍𝖊𝖆𝖉 (@aimhdesigns) reported

    anyone else having problems on @tescomobile with no service or data no matter where you go???

  • VinnieLouu Katie (@VinnieLouu) reported

    @tescomobile To contact anyone. The person on your live chat is full of crap as well. Check my account and see how many times me and my partner had to call each other within an hour because you can’t provide services I pay for. I cannot sustain a phone call EVER.

  • EvilStartsAt15V 💥 Evil Starts At Fifteen Volts 💥 (@EvilStartsAt15V) reported

    @tescomobile @JRAnalytics__ You reply with that sentence 11 mins after they messaged you? Are you ***************? In my experience Tesco mobile is absolute shite. No wonder you're not putting up the prices because the donkey driven network you have needs no more funding. Terrible just absolutely terrible.

  • JRAnalytics__ JR Analytics (@JRAnalytics__) reported

    @tescomobile absolutely astounded at the horrific service we’ve received. Returned our contract within 14 days as you don’t offer WiFi Calling. Returned the device in the same condition we purchased it in and today you’ve taken £600 out of my account and I cannot pay my rent

  • gadudman Glenn Dudman (@gadudman) reported

    @tescomobile So you don't provide an acceptable signal,then charge penalty to move
