    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 😡

  • 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?

    @tescomobile Unable to test, going to store after work though number of posts I’m seeing where people seem to have identical issues is concerning. Multiple reports of mast issues, are they all faulty? #notgoodenough

  • Trudgillz Trudgill (@Trudgillz) reported

    @tescomobile Thank you Maria, I have tried that number but it does not support my textphone? Do you have a text phone number as I am hard of hearing?

  • wendysav Wendy Savill (@wendysav) reported

    Huge thanks to Asif from Customer Care at @tescomobile who delivered what he promised. Tesco he is a credit to your team

  • brandon67329023 Brandon Bell (@brandon67329023) reported

    @tescomobile hello Tesco mobile I am currently having issues with my mobile data and messages what should I do?

  • nicholesprankl1 nichole spranklin (@nicholesprankl1) reported

    @tescomobile I changed my sim over yesterday but I can’t login to account yet as it says my number still isn’t Tesco number and I can’t receive calls yet 07583694291

  • Trolleybirds Caro Glasgow (@Trolleybirds) reported

    @tescomobile Hi Maria, it was ”processed” on 8/9, spoke to another customer services rep on 13/9 who said it can take 3-5 working days!!! So disappointed to say the least 😣

  • americanguy11 cory😊! (@americanguy11) reported

    @tescomobile no 5G in my area. wtf

  • CatTyler1 Cat Tyler (@CatTyler1) reported

    @tescomobile Really dissatisfied with your customer service when I've phoned several times over the past few days. Need to return a phone that isn't working but is still within its 12month warranty, and your advisers are being unhelpful and rude. Will visit my local shop instead.

  • Harrys3rdNipple Harrys3rdNipple (@Harrys3rdNipple) reported

    @tescomobile I already did that. It said that it's slow in my area and you're working to make it better or something. I just don't understand how it was fine until a week ago. V hard to watch videos etc

  • magsLancashire Mags (@magsLancashire) reported

    @tescomobile I had to drive 35 miles to your store at Daneston Aberdeen. I would lime to add that Phillip in your phone shop has gone above and beyond with customer service. Extremely helpful with advice. I now have a new phone and he helped transferring everything across.
