    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

  • 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?

  • 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

  • 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

  • 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?

  • greatwhitebark CathyM (@greatwhitebark) reported

    @tescomobile Again, no use to an elderly person who doesn't use a computer. Is it too much trouble for an actual human being to help her? She's lucky to have family to step in but she hates to ask. Not everybody has that. We will all be old one day...

  • VickiWilson1975 Vicki Wilson (@VickiWilson1975) reported

    @tescomobile Hopefully it won't be too long as I'm not happy paying for a service I can't use. Especially as I need it to run my business

  • michellehump3s Michelle Coyle (@michellehump3s) reported

    2/2 So today @tescomobile got me stranded as I use my Maps app as a SatNav whilst doing home Visits for work. Nothing would load, completely lost in the middle of a town I didn’t know!! Never happened with o2 but always with you? Why?

  • MarcMurray92 Marc Murray (@MarcMurray92) reported

    @tescomobile 105 minutes on hold tovyour irish support line and can't request a call back. Need somebody to call me.

  • toodlepipette Kate Armitage (@toodlepipette) reported

    Tried logging in to @tescomobile because my phone is broken but it won't sign me in until I type in a code that has been text to me... I can't receive the text until I get a new phone but I can't log on and order a new phone until I get a text...

  • DigitalSpirit1 ● Susan Forgie 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@DigitalSpirit1) reported from Haddington, Scotland

    Is anyone else in #EastLothian having trouble with their @tescomobile service? I've not had a network service since last night.

  • rooke_allan Allan Rooke (@rooke_allan) reported

    @tescomobile Read the chat that I have been involved with for last few days then perhaps you will understand until this is sorted I will continue publicly there are a number of issues but no one seems to answer all of my questions and keep fobbing me off

  • 661_aac 661AAC (@661_aac) reported

    @tescomobile My network has been down for a day.Whats happening?

  • VickiWilson1975 Vicki Wilson (@VickiWilson1975) reported

    @tescomobile 3 days no signal now I have 2 bars but emergency service only. This is beyond a joke

  • TheRevBLove The Rev Bearded Love (@TheRevBLove) reported

    @tescomobile I have now been lied to twice by your operators, and for the 4th day in a row you’ve been unable to take my old mobile number over, and no-one seems to be able to tell me why this is. Is this your standard customer service?
