  • 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?

  • 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??

  • 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

  • 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 😡

  • 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?

  • greenyenergy Green #AbolishLockdowns (@greenyenergy) reported

    @tescomobile I've only ever been on PAYG so never had this problem. @giffgaff are great!

  • xJFCHx Jax (@xJFCHx) reported

    @KatiesDisorder @tescomobile EE are horrific. I moved to an area that was said to have great signal. They had knocked down a mast, so I could make calls or receive texts by walking to the end of my street. Numerous signal boosting boxing offered but never arrived. Left paying for a phone I couldn't use.

  • TheNutronic Nutronic (@TheNutronic) reported

    @tescomobile Every network, especially mine at @EE. I might move from them actually this year, even though they've offered me a free and early upgrade.

  • cannabished 𝐄 𝐍 𝐎 𝐋 𝐀 𝐆 𝐀 𝐘 (@cannabished) reported

    @porcinesludge @dazzypops @tescomobile £20 PAYG with Superdrug Mobile. Unlimited everything. They use Three network, its not the best but for 20 quid and a non contract I can't really complain!

  • xox_saima_xoxo saima hussain (@xox_saima_xoxo) reported

    @tescomobile @ThreeUK data or service never work

  • 80rebeccaM Rebecca Reynolds (@80rebeccaM) reported

    @tescomobile You should be sorry Tesco... I’ve had issues with voice calls for weeks and your online help is hopeless

  • martim_hamilton martin hamilton (@martim_hamilton) reported

    @tescomobile hi I have no signal in the hednesford area Ws122nw is the network down?

  • ronnieandreggie RMcB (@ronnieandreggie) reported

    @tescomobile I changed provider to BT. Me and the husband. Was treated like **** when I complained. Glad that at least 100 people now know about Tesco Mobile's crooked ways.

    @tescomobile Three have got the best customer service in the world
