    @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

  • 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 😡

  • 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

    @tescomobile firstly 4g running slow all weekend. To the point I couldn't connect to my push doctor appointment this morning. Secondly tesco mobile app doesn't recognise my postcode. Thirdly customer service sends me a link that doesn't work.

  • TheBuzzWagon Ashley Read 💙💛 (@TheBuzzWagon) reported

    @tescomobile For some reason I always get this problem with texts to numbers beginning with 8 that may incur additional charges despite ticking box accepting it

  • _bxston Demi :) (@_bxston) reported

    @tescomobile It’s not issues all the time but the real issue he’s having is his 4G not working and such

  • Charlot03365887 Charlotte Willshire (@Charlot03365887) reported

    @tescomobile shocking service, trying to port mobile number since 24th August, should take 24 hours, its been 14 days. Both numbers now inactive no number for work or banking. Keep getting fobbed off, getting cross pathetic customer service, being lied to constantly.

  • HelenDoyle_5 Helen ♊ (@HelenDoyle_5) reported

    @tescomobile I only moved to you because my husband has a phone with you. He is also having the same issue as me. Really disappointing after 16 years with EE and no signal issues.

  • oliversmission Olivers Mission 🇬🇧❤🇺🇦 Посмішка Іллі (@oliversmission) reported

    @VodafoneUK Wish we never moved from you to @tescomobile Data drops, coverage is poor, especially inside, no wifi calling etc. Pay your money, take your chances. Vodafone were getting too expensive, but never had an issue. #dailyissues with Tesco mobile. Three contracts, all have issues.

  • Tom_T91 Tom (@Tom_T91) reported

    Can someone at @tescomobile help with a logging in issue. I sit on the phone to customer service to get cut off 3 times in a row and web chat is not working. I just want to log into my app with my newly ported number.

  • _bxston Demi :) (@_bxston) reported

    @tescomobile can you help me out with my boyfriend please ever since he’s been with Tesco mobile his 4G just doesn’t work anywhere..

  • _bxston Demi :) (@_bxston) reported

    @tescomobile How would that work though when his phone is locked to Tesco network? There’s no way of us testing this out on another phone..

  • SGC1978 Simon Chambers (@SGC1978) reported

    @tescomobile I've spent an hour this morning trying to sort out your issue with customer services, but the solution offered is far from ideal and requires further, unnecessary work on my behalf to resolve. Not happy and feeling concerned by what has happened / is happening.
