    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

  • 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

  • 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?

  • 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?

  • 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?

  • 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

  • annewmc Anne Mc (@annewmc) reported

    @tescomobile Can you please confirm if the Tesco network covers Jersey? Your network coverage map does not recognise either the post code I am entering or St Helier.

  • jilltrevail Jill (@jilltrevail) reported

    @tescomobile after over 8 years as a customer My phone won't charge. 9 days minimum to repair with no cover phone You say as it's past 2 years, so I can't get an early contract. You failed to mention that when I made the contract. So I pay £120 or have no phone. You're a disgrace

  • JanetSimmons8 Janet Simmons (@JanetSimmons8) reported

    @tescomobile checker is telling me that the signal is good but phone says none, and I can’t call or text??

  • toxic77rose ⭐️ Miss T ⭐️ (@toxic77rose) reported

    @tescomobile I have checked the link and also spoken to someone in my local O2 store. They are working on improvements in my area. However i have not had any signal all week. Only being able to use my phone via wifi at home with a different network.

  • colwrbn Col.W. (@colwrbn) reported

    @tescomobile Who ******** has a 'dream phone' ? How sad do you have to be ?

  • corrilan Jason Bassett (@corrilan) reported

    @tescomobile That's OK, I have now reset my password to something not as secure - my previous one had lots of punctuation characters in it. I can now login.

  • ejr88 Emma Rice (@ejr88) reported

    Absolutely terrible service trying, and failing, to upgrade with @tescomobile today. Expected better when approaching ten years of being a customer…

  • Bishop42998267 Bishop (@Bishop42998267) reported

    @tescomobile Just have a card and a person with a thumbs up.. I know the idea is to appeal to your customer base but honesty is better than some lightning.
