  • 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?

  • 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

  • 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

  • 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??

  • 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 😡

  • 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

    Really, really regretting leaving @O2 and moving to @tescomobile . Tesco service has been absolutely shocking. I've been waiting for them to port my number since 6th Dec. Multiple online chats, conversations with staff in-store, DMs on here and zero progress.

  • davecarson88 dave carson (@davecarson88) reported

    @tescomobile Thanks Jade, I got through on the 0345 number but the network 4455 number is not recognised

  • caroljane1 Jane Doyle (@caroljane1) reported

    @tescomobile This number is not working

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile I have tried all networks same issue

  • offley78 Pete Offley (@offley78) reported

    @tescomobile when are you going to provide a service for smart watch’s so they can be use on 4g without a phone. To use my watches I need to have my phone with me. Get with the times.

  • JakeHamblin20 Jake Hamblin (@JakeHamblin20) reported

    @tescomobile hi, is your phone line having problems? I am trying to call but the call cuts out about 3 seconds in every time.

  • HofKnocker Adrian Tompkins (@HofKnocker) reported

    @tescomobile And possibly the reason I didn’t get your call was because I was at work with no signal. Ironic right?

  • Dogearedtatty H (@Dogearedtatty) reported

    Why is @Tescomobile mobile data (provided by @O2) so terrible in Exeter? Forget 4G, forget even 3G. It was even failing to get EDGE/GPRS.

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile Only have E signal (2G) so no error just no 3G and above

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile It worked when in Italy 4 weeks ago so again confused as to why you say it is a hardware issue?
