  • 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?

  • 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?

  • 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??

  • 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 😡

  • 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

  • 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?

  • 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

  • lisaSmi10224679 lisa Smith (@lisaSmi10224679) reported

    @tescomobile been with you for years, added by granddaughter to my account no problems, tried to add my husband and now you have lost my number - being passed from pillar to post - not good enough

  • robert490 Robert Nesbitt (@robert490) reported

    @tescomobile It Never Works I Ring a Friend but All I Get is Caller Can’t be Able to Answer The phone But Leave your Name And Number And I Will Get Back to You

  • wildlifelover0 Wildlife mad (@wildlifelover0) reported

    @tescomobile Poor signal ever.

  • Kiff Kiff Lloyd (@Kiff) reported

    @rya89160347 @tescomobile I used to be on EE which was decent coverage, since changing to Tesco it’s garbage in every part of the country I’ve visited (significantly worse than other friends on O2) I suppose you get what you pay for, I won’t be renewing I don’t think…

  • Jenflix01 Jen Flix (@Jenflix01) reported

    @tescomobile @spudjoy It’s awful EVERYWHERE. I went to newquay for a week and had 0 signal I had to tether off my friend using EE for the entire time.

  • AndrewBlewett3 Andrew Blewett (@AndrewBlewett3) reported

    @tescomobile Tesco mobile took almost £1000 in payment from a broken & out of use phone - an account they knew was dormant. Offered a token mini-refund with two week limit. Terrible service. Never again.

  • BabyBoomer1960 Karen 🌻 (@BabyBoomer1960) reported

    @tescomobile @Tesco Contacted them, they transferred my call to DPD…as I said last week never again! This has been one farce from the moment we received the phone.

  • OaPhumin OAPhumin (@OaPhumin) reported

    @tescomobile If only you had WiFi calling for those of us in cities and elsewhere where reception in our homes is pretty poor

  • Anitafallsalot Anita Egan (@Anitafallsalot) reported

    @tescomobile @IanHump27942219 Funny how @tescomobileire have issues with data usage too! They know they do and they all just keep lying to their customers
