    @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?

  • 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

    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 😡

    @tescomobile I don't shop for groceries with Tesco since their delivery charges increased (if you could get a slot) however their mobile phone service/prices are about the best I have found so far.

  • nen_bee NenBee (@nen_bee) reported

    @tescomobile Went to a Tesco the first time in ages, never again, all this Clubcard rubbish everywhere. Just provide a decent price for everyone. Very misleading way of pricing things. People can't afford to be 'tricked' like this

  • youngqueenvic mol 🐮 (@youngqueenvic) reported

    @tescomobile worst service i’ve EVER experienced in my life. constant SIM problems and never any help or support. useless service

  • MaulaJatt18 Maula Jatt (@MaulaJatt18) reported

    @tescomobile You are clearly not reading or understanding what I am saying. Since Tescomobile closed its customer service site in Bury, its gone to the shitters. 3 things I mentioned in previous tweet, refused a manager, account to be re credited which still hasn't and been mis sold a contrac

  • Cookie32243716 Cookie (@Cookie32243716) reported

    @tescomobile seriously need to enable their network to make use of wifi calling. Tesco being left behind by all other networks

  • CammieRacing Cammie Racing (@CammieRacing) reported

    @tescomobile Remember, Tesco are about the only network NOT to provide calls over wifi.

  • BossUniv Univ.Boss (@BossUniv) reported

    @BlokeZx @RoidyRandy @tescomobile Price they charge for a plan is upto them. My issue is calling some 0% interest, when they actually take extra money by selling the phone at higher price. Plus many Don't know - Some lenders see it as personal loan affecting credit rating/affordability for mortgage.

    @tescomobile **** Tesco. Go to Aldi or Lidl and pay a third of ehat Tesco charge

  • Matedwards7 Matt Edwards (@Matedwards7) reported

    @tescomobile Never use Tesco’s for home deliveries now since they introduced the club card discrimination.
