  • 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

    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?

  • 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??

  • 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

  • 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

  • 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

  • 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?

  • Gardenswhatever ArtsandCrafts1954 (@Gardenswhatever) reported

    @tescomobile There is no point in sending you a private message. The last problem was only sorted out by the ombudsman and I’ve a letter that states they will give me £30 in compensation due to not being able to use the phone. It’s now been fixed after6 months of complaining but no money.

  • MichaelPocock18 Michael Pocock (@MichaelPocock18) reported

    @tescomobile @MrsGunner I've been with Tesco mobile for 6 yes without any problems at all

  • classics123 tony west (@classics123) reported

    @tescomobile Probably because you cant get through to a complaint department, on line just get ignored.

  • mccl65 Lmccl65 (@mccl65) reported

    @tescomobile @MrsGunner Definitely choose Tesco mobile. My local Tesco delivered exceptional service. #Calne

  • dunstablian John (@dunstablian) reported

    @tescomobile Have 3 phones on my account for which i pay the bill. Mine my wife and daughters. Want to see all three bills on line my laptop to check how much each is costing how do i do this as i had problems with my previous supplier ID ?

  • mjames276 Mark James (@mjames276) reported

    @tescomobile are your online and text PAC request services broken, or are you now refusing to give a PAC online/by text?

  • Laurapringle_11 laura 🦔 (@Laurapringle_11) reported

    @mouthwaite @EE EE is awful. They over charged me on my bill one month when I phoned to say it was wrong they told me I had to pay it or be blacklisted. I moved to @tescomobile and have been with them years! Best decision 👏🏻

  • sarahyhirons Sarah (@sarahyhirons) reported

    @tescomobile my phone is amazing, the signal continuously let's it down, so disappointed. Is there anyway go boost it?

  • Turneeps5 Turneep 💙🇮🇸🇩🇪🇪🇺 (@Turneeps5) reported

    Finally have sorted a replacement #phone for idiot teen. This time it’s insured (she’s paying), it’s a pain that @tescomobile won’t allow a non Tesco number to be set as ‘main’ number for the account though… if the main number gets stolen then you can’t log into your account!

  • andymblackmore Andy Blackmore (@andymblackmore) reported
