    @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

  • 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?

  • 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 😡

  • CH7l5 Briefcase ****** (@CH7l5) reported

    @tescomobile hi, there’s been a mast down now for ages near where I live - I know it’s out of your hands per say - but when is it going to be repaired I can hardly use my date when out & about without flicking in/out of airplane mode. Cheers.

  • archuk123 David Archer (@archuk123) reported

    @tescomobile I know. And I’m saying that it’s a con. I should be allowed to continue the other agreement separately. Yes I know it’s in the small print. Thank you for the reply (over a month since I originally posted). Tesco? Never again.

  • GinaTE16 Gina TE (@GinaTE16) reported

    @tescomobile For years we had all our phones with Tesco. In the last month I haven't been able to make phone calls or use Internet. Rang 10 times, and their customer service is awful, they don't know what to do👎. 3 came to the rescue this month. 👍

  • Peter__Heap Peter Heap (@Peter__Heap) reported

    @Stephanie_Jane_ @tescomobile Both me and my mum had the same issue Stephanie and I had to port my number out from Tesco Mobile to a different network because the advisers on live chat, over the phone and on Twitter were not bothering to help. They instead fobbed me off saying "everything is working fine" 🤬

  • sairh1972 sarah kendrick (@sairh1972) reported

    @tescomobile @WhichUK No refund issued though discussing service cancelled after 2 days 11/4 still waiting for refund !!! Nearly 2 months customer care say it’s not there fault

  • sairh1972 sarah kendrick (@sairh1972) reported

    @tescomobile discussed in your service ordered 2 sim only deals paid £14 upfront on the 11th of April called up on the 13th of April to cancel as u don’t do Wi-Fi calling was told the refund would go back into my account after 2 weeks but nothing !!!

  • Diane_Ihirwe Diane (@Diane_Ihirwe) reported

    @tescomobile charging me over €150 for data I used (in 1 day) of despair is horrible. After years of being a loyal customer, they can keep that nbre bse I can't afford to pay 150 and it's extremely inconsiderate to not make allowances for these things. I would 100 not recommend!

  • potty45 Jane Rees (@potty45) reported

    @double_drax @tescomobile We are having the same problem, and no-one seems to be able to help, so another customer lost!! What’s worse I have a colleague Clubcard.. so not quite the best I would say!!!!
