    @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

  • nigelbendybus Nigel Smith (@nigelbendybus) reported from Cardiff, 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?

    Hey @tescomobile👋Contract started 31/10🎃All trick & no treat, still can't use 📱. My online chats, emails, calls & store trip hasn't helped, even emailed CEO @clairefweir, but I've been 👻ed. SOS @OmbudServices Can't wait 8 wks, getting extra charges & can't use phone. Pls RT.

  • lcychlmnsll Lucy Chloe 🤍🦩 (@lcychlmnsll) reported

    @tescomobile For some reason when people try to call my number it says it doesn’t exist and some of my messages are not coming through. Please help!

  • sirtonybond tony bond (@sirtonybond) reported

    @simon_euro @tescomobile Do you keep the phone on all the time? Static electricity can disturb electronic devices. Surprising how many times my mystery problems have gone away after re-starting devices. Try switching off completely. If the battery is removable, remove, replace (also the SIM) & re-start.

  • clexoris zed (@clexoris) reported

    @tescomobile Hey guys. I've been waiting nearly a month for a £650 refund for a phone I sent back. Called a week ago to chase this but still not heard anything. Getting very anxious about this, it's alot of money. Please can you help?

  • Albamale2008 Douglas Smith (@Albamale2008) reported

    @tescomobile still awaiting a reply from my complaint email. Not happy. Always been good service, has something changed?

  • jaynecowland Jayne Cowland (@jaynecowland) reported

    @tescomobile Attempts to port my father's number have all failed. Your have de-activated his existing sim leaving an elderly, vulnerable customer uncontactable. Today i'm told its an issue affecting thousands of customers and no known rectification date. Really not good enough!

  • admforbes Alex Forbes (@admforbes) reported

    @tescomobile I have had no data since getting a new SIM 2 weeks ago. Your call centre tell me a different thing everytime; today it's a system wide problem with no fix date. Is this true?

  • biscuitsutd ThelastPaul (@biscuitsutd) reported

    @tescomobile absolutely disgusting customer service today, and quite honestly I’m ready to leave you. A thread…

  • simon_euro Simon 🇺🇦 #StandWithUkraine #FBPE (@simon_euro) reported

    @sirtonybond @tescomobile I worked for EE when they were Orange. We wouldn’t do anything until everything had been turned off and on again. Had new sims and phones TNA unfortunately. This problem is related to the Caller Line Identification Presentation, it’s a network problem.
