    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

  • 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 😡

  • RazNazir Razwan Nazir (@RazNazir) reported

    @cymraesydwi @tescomobile That’s really bad …. Nowadays all the operators are trying to differentiate their services through customer journey and experience, yet it seems Tesco Mobile can’t provide the basics !!!!

  • RockRollDriver 𝕽𝖔𝖈𝖐𝕽𝖔𝖑𝖑𝕯𝖗𝖎𝖛𝖊𝖗 (@RockRollDriver) reported

    @Tesco @tescomobile Useless service, no available phone number to check stock at local branch, no way of checking stock of ONE item, at this specific branch via their app. App now uninstalled and attempting to source item elsewhere as #Tesco dont want my business!

  • Lindsay_Brunt Lindsay Brunt (@Lindsay_Brunt) reported

    @paulrdon @tescomobile It’s so bad! But Tesco will blame your phone or area for the issue… just had mine checked at Apple Store and it’s deffo not the phone!
