    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 😡

  • 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?

  • 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?

  • 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

  • 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?

    @tescomobile hi, I need some help downloading a bill please?

  • Steve197Uk Steve197_uk (@Steve197Uk) reported

    @tescomobile @WhichUK I will cancel this contract if you do not send me a contact email address without all the form filling beforehand. She has no login details as she only had the phone twelve days

  • ScottLittlewoo6 Scott Littlewood (@ScottLittlewoo6) reported

    @tescomobile Your WebChat Help is not working as expected. Operating hours are stated as 07:00 to 19:00 it's 10:40UK and the widget wont load / show in multiple browsers. I need help about reporting an issue with contacting help, please help :)

  • Sausagef1nger Alex Mckinney (@Sausagef1nger) reported

    @tescomobile @WhichUK Maybe you should goto highwoods colchester because your connection sucks and your crap 3rd party customer service is pathetic. I am taking all my contacts and leaving Tesco. Your complaints procedure is crap also. Ofcom will be informed.

  • MrCADwiz Everest, Sam (@MrCADwiz) reported

    @tescomobile I don't remember getting one. Mind you it is only when I'm at work mainly. But I only used to be 4g not 5g so could it just be the signal for 5g isn't as stronge where I am?

  • CliffSinc Cliff Sinclair (@CliffSinc) reported

    @tescomobile it says call forwarding connection problem or invalid mmi code

  • Jamiewaterhous1 Jamie Waterhouse (@Jamiewaterhous1) reported

    @tescomobile Good morning, I hope you are well. Is there something wrong with the Network in Bromsgrove? 75% of the time over the last few months there is mo 4G and my phone only has EMERGENCY CALLS ONLY showing

  • MrCADwiz Everest, Sam (@MrCADwiz) reported

    @tescomobile not very happy at the moment ever since upgrading to a new phone I seem to having data issues, when I never had then before with my older phone. Any idea what the reason could be?

  • felizecalvo kahlköpfig (@felizecalvo) reported

    Been with @tescomobile for I don’t know how long now. Go to renew sim contract, offers are not suitable and no effort made on customer retention front. Sad really

  • CliffSinc Cliff Sinclair (@CliffSinc) reported

    @tescomobile Deep Breath I have done it all, personally and on line. I have spent 30 minutes with the 'technical service' person on the phone. and an hour on line I cannot access the settings. The **61*905*11* just disconnects me. My app will not connect me to web or twitter
