    @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?

  • 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

  • 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

  • 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

    @CaseyStu @OpalM00nstone @tescomobile Don’t buy a phone from them because if it breaks and it’s not your fault they won’t replace it or fix it.

  • TimskelperTav gerrard for 10iar (@TimskelperTav) reported

    @tescomobile @O2 I feel I deserve an apology for the **** service

  • PeterGibsoNotMP PeterGibsonParodyMP (@PeterGibsoNotMP) reported

    @tescomobile I'd agree but at least I don't have to put up with being on O2's slow *** network. Sorry, not sorry

  • CraftyGirl72 CraftyGirl72 (@CraftyGirl72) reported

    @tescomobile Only nightmare network I've needed a sorry from is yours! Friend would phone my landline and tell me to answer my mobile/texts... had to go out in to street to get anything! Total joke and was trapped by your contract! Never again...

  • XanderWright3 Xander Wright (@XanderWright3) reported

    @pritybraun @tescomobile @unitedutilities Fine if you're in a big household with lots of people using a lot of water. Not so much if you live on your own. Then they tell you to try and conserve your water usage to help save the planet.

  • Peachyfruitcake Peach (@Peachyfruitcake) reported

    @tescomobile Three! I spent a nightmare year marking the days off to contract end - signal.was appalling & could never get on the internet! Didn't go back to Tesco though as Sky gave me a better deal & zero issues!

  • JayMorps Jay (@JayMorps) reported

    @CaseyStu @OpalM00nstone @tescomobile Tesco does work using the O2 network so they are the same but cheaper tbh

  • JamesBrannagan9 James Brannagan (@JamesBrannagan9) reported

    @tescomobile Hey @tescomobile I have been with you since I had a phone and when I go with the cheapest plan because I’m having financial problems you have to make my service and data plan bad your website said that I could get 30GB of data 5000 texts 5000 calls and you did the bait and switch

  • Lloyd13682635 Lloyd (@Lloyd13682635) reported

    @tescomobile I've never understood how ofcom have allowed this to be legal
