    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

  • 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?

  • 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

  • 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 😡

    @Pig_Maiden @tescomobile Run from Tesco Mobile as fast as you can. They've damaged my credit score, admitted it and refuse to fix it. Plus their payment system isn't compatible with industry standards. Terrible company.

  • Pig_Maiden Kerry Canning (@Pig_Maiden) reported

    @seymourjames3 @tescomobile Thanks Jimmy but I've tried everything. I'm done and I don't have the time, money or inclination to travel to Irvine chasing a less-than-useless service from a bunch of money-grabbing charlatans. I should have listened to good advice and gone with Sky Mobile.

  • VinnieLouu Katie (@VinnieLouu) reported

    Nearly 3 days have gone, and still no response from @tescomobile. My partner is on 02, and his friend is on GiffGaff… they have good signal. Sort your **** out. #pisstake

  • AnnabelleHeywo1 Annabelle Heywood (@AnnabelleHeywo1) reported

    @tescomobile hi, is your webchat not working today…?

  • Pig_Maiden Kerry Canning (@Pig_Maiden) reported

    @tescomobile @seymourjames3 That's now 3 SIM cards and 11 phone calls to Tesco Mobile. Still no data & no calls/texts again today. Never again, Tesco. This is not an isolated incident. Do you even bother to read your reviews? The way you are treating your customers is utterly shameful. DO BETTER!

  • SmileyMatthew91 Matthew Hall (@SmileyMatthew91) reported

    @tescomobile I’ve recently upgraded my SIM card to 5G within 2 months. I’ve been advised that if 5G isn’t available I’d get 4G. Mostly getting edge service at home and work.

  • SmileyMatthew91 Matthew Hall (@SmileyMatthew91) reported

    @tescomobile No problem, I’ve private message @tescomobile with the details

  • seymourjames3 Jimbooooo (@seymourjames3) reported

    @tescomobile @Pig_Maiden Listen thanks for you help but I have gone over this at least 4 time with you chat people and twice in store Tesco have had there chance. I have had enough of Tesco mobile and going round in circles and the lack of knowledge or any understanding from some customer care team

  • Richperks 𝗥𝗶𝗰𝗵 𝗣𝗲𝗿𝗸𝘀 (@Richperks) reported

    @tescomobile customer support network is a farce. Two months of trying to resolve a problem; have resorted to lodging a formal complaint online (under the heading ‘please ask your question here’)…it’s not a question Tesco! Automation and bots = very unhappy customers! Unreal!

  • seymourjames3 Jimbooooo (@seymourjames3) reported

    @tescomobile @Pig_Maiden The fact is I paid for a service my kids could not use properly because no one at tesco ever informed me that the sim card was restricted or I would have got it unlocked and policed the usage myself also why was it only these 2 cards that were locked and not the adult ones.
