    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

  • 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

  • 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?

  • 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?

  • 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??

  • 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 2 Tesco mobiles in my household unable to connect to home wifi today, is there an issue with the network?

  • Cubz_1 aaqib ali (@Cubz_1) reported

    @tescomobile Atrocious customer service, advisors haven’t a clue giving conflicting information. My tarrif was supposed to change on the 9th, the change hasn’t taken place little help offered and basically told to suck it. Great way to treat a customer of 11 years.

  • ccbespokeart Char Callin (@ccbespokeart) reported

    @tescomobile @Tesco can someone get in touch with me ASAP or tell me who to contact to change my email account attached to my phone number and my club card as my email was hacked. Thank you for your help. #cyberfraud #onlinefraud RT

  • DeniseM30781820 Dee Martin (@DeniseM30781820) reported

    @tescomobile So apparently I dont meet the criteria for a Tesco mobile phone contract 🤔 and yet I have a Tesco Credit Card, an excellent credit score, no Cifas markers, no outstanding debts, no CCJs and yet still I've been turned down for credit 😤

  • westaerialphoto Phillip West (@westaerialphoto) reported

    @Mrs_A_Campbell @tescomobile @SamsungMobile It wouldn't surprise me if this was a Samsung fault. My wife had the A50 when it first came out and it was nothing but trouble. Wifi kept dropping out, glitchy camera etc. In the end I just bought a Huawei phone sim free. Samsung are aware of some serious software issues but....

  • sarahyhirons Sarah (@sarahyhirons) reported

    @tescomobile so to use my phone now I need to turn it off/on,apparently I'm not getting texts due to the senders network, what a load of crap I've been fobbed off with again.Expected more from u @tescomobile can't belive I'm saying this but I wish I'd stayed with @VodafoneUKhelp

  • bloognoo Bloognoo (@bloognoo) reported

    @tescomobile I am receiving scam calls from Tesco mobile numbers roughly once a day claiming to be @HMRCgovuk . Never the same number twice, number disconnected if I call back to try and identify them. I think your SIM provisioning system has been hacked.

  • sarahyhirons Sarah (@sarahyhirons) reported

    @tescomobile I've had to change my sim card for no signal for a week. No other changes.

    @tescomobile Need Help😭😭

  • Mrs_A_Campbell Mrs Alison Campbell (@Mrs_A_Campbell) reported

    @tescomobile It makes it horrible because I have a sd card in but I can transfer anything to it. I use to be able transfer games to it when I had my older Samsung it was good to free up space but I can't now won't let me. All it does is let me put pics on.
