    @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?

  • 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

  • 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

  • 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 😡

  • 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?

    Absolutely appalled at the service my daughter has received from @tescomobile trying to take out a phone contract… 5 people all saying different things and still no phone contract after 4 days of trying.. so much for the recommendation I was going to transfer too.. not now! 😡

  • ValentinLewis12 Valentin Lewis (@ValentinLewis12) reported

    @tescomobile @PrivacyMatters I had same problem with Tesco mobile,Tesco run on O2 network,I have 3 year contract with them they cancelled my SIM contact but I still have to pay for the Phone 🫤 I'm with voxi mobile now run by Vodafone

  • LeHammy1975 Graham (@LeHammy1975) reported

    @tescomobile Thanks Callum - Looks like a nearby phone mast isn’t working as it should, sorry. Our engineers are likely to be on the case already, and your service might come and go until we fix it

  • mikestrubel Michael Strubel (@mikestrubel) reported

    @tescomobile @EE Hi Maria, I am afraid we still have problems. The new phone has the old telephone number on it now, which is great. Unfortunately when my father is texting the phone is sending it from the new number it came with which is a bit weird. The old phone is turned off completely.

  • AJsojourn Parka (@AJsojourn) reported

    @tescomobile i honestly don’t think this can get sorted. We’ve constantly been back and forth with support via live chat and calls. I swore once as a general comment not even being aggressive and a colleague threatened to get my calls and texts investigated. It was at the situation not him.

  • Wrightbro5 Wrightbros (@Wrightbro5) reported

    @tescomobile Sadly you have not been able to help me with my medical device. Your PAC service is not working. It says I have multiple accounts but I am texting from the number I want a PAC code for. Help #badservice

  • meloni1961 Mel (@meloni1961) reported

    @PaulCole @tescomobile It's worse on White Cliffs and rarely happens where I am. I now know how to set network manually.
