  • 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?

  • 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

  • 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

  • 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?

  • 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??

  • richwould Richard Would (@richwould) reported

    @tescomobile Incorrect, it is sold as a 2 year contract for service, 3 year for phone. But I cannot change the service contract despite it having run out due to the 3 year phone contract.

  • Chris_MK3 Chris Grant (@Chris_MK3) reported

    @markhoose @tescomobile They increase every April without fail. I suspect you just haven't been paying attention

  • CyprusPictures #FyldeCoast Musings (@CyprusPictures) reported

    @AEWMike @tescomobile @EE What do you get for £99 a month? We pay for landline/broadband including a fixed amount of free calls to landlines and mobiles which is £32pm and purely PAYG on mobile. Have never been data dependent on mobile and never held a contract since 1995. It's a ridiculous amount to pay!

  • VgnRav Rav (@VgnRav) reported

    My mum is with @tescomobile and doesn't get voicemail and doesn't see if someone is calling her whilst on the phone. Sounds like a carrier issue rather than a phone issue? She has a Samsung

  • TonyJonesCITP Tony Jones CITP FBCS (@TonyJonesCITP) reported from Wrexham, Wales

    @tescomobile I have been happy enough with the overall service, but the network signal could have been better. Hence the move to another party. Thanks 👍

  • EmmaBadge Big Sister Willow (@EmmaBadge) reported

    @tescomobile You say this but after 10 years I am moving away from Tesco mobile. I am paying more on this network than I need to compare to the others.

  • RefugeeNik Nikos 🇨🇾🇬🇷🇬🇧 (@RefugeeNik) reported

    @tescomobile EVERYONE wants their price frozen. They should NEVER have to ask.

  • MooreMolenan Robert Moore (@MooreMolenan) reported

    @tescomobile Provide a reliable service first then we will talk about the damn bill.

  • tigressuk tigress (@tigressuk) reported

    @tescomobile Not sure why you’re “sorry” for other networks?! I wanted to be on your network and you couldn’t provide a signal to my village! So I had no option but to go to with an alternative!!

  • LaurenSatsuma 🎃Spooky Lauren🎃 (@LaurenSatsuma) reported

    @tescomobile I've always been a Tesco mobile customer so I didn't actually realise other networks were doing this. Yikes.
