    @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?

  • 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 😡

  • 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?

  • 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

  • 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

  • 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

  • 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??

  • DeSarahdean1992 Sarah Dean (@DeSarahdean1992) reported

    @tescomobile Hi Sean sorry for the late reply I was seeing Elton John live last night in Liverpool. I think their was no power going to phone to charge the phone. I think the usb phone charger in the car is not working properly. I have tired other phone chargers at home it was working fine

  • bryanmcc74 Bryan 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@bryanmcc74) reported

    @tescomobile @O2 No it was good but since out of lockdown it gotten really bad

  • PSUKAndyK PSUK AndyK | A.King (@PSUKAndyK) reported

    Had two phones in two months from @tescomobile and neither of which work. I use my phone for work at times, but tescos only options theyve given me is to either 1) pay off my contract or 2) send it in for repair My first s21 @SamsungMobile screen broke, now this one has issues

  • Joanne76006149 Joanne (@Joanne76006149) reported

    @tescomobile are there any problems with the network today? I am unable to make/recieve calls texts and no mobile data

  • anwyldave Dave Anwyl (@anwyldave) reported

    @tescomobile your repair centre left me a message and sent me an email asking me to contact them but the number doesn't work. Is there any other way of contacting them?

  • joannescotland Joanne Scotland (@joannescotland) reported

    Why are mobile phone companies allowed to put time limits on PAYG top-ups. I topped up my son’s phone on @tescomobile on Thursday with £5 for emergency calls as he had a school trip. But it’s only valid until 16/7/22. I’ve bought that credit, so why can’t he keep it? 1/..

  • Pig_Maiden Kerry Canning (@Pig_Maiden) reported

    @seymourjames3 @tescomobile Thanks, Jim. Utterly useless shower of charlatans. Happy to take the money but no regard for customers. I've documented everything. If not resolved soon I'll be bypassing Tesco altogether and taking my issue to the relevant ombudsman. So many folk having similar issues. So poor.

  • PalmerC73 ⓒⓛⓐⓘⓡⓔⓟ (@PalmerC73) reported

    So disappointed with @tescomobile I’m 9 months away from ending my contract and having issues with signal at my dads and sue to my brother needing a kidney transplant I need coverage all the time. Despite my efforts I’m getting nowhere. I can’t afford the exit fee but need signal
