    @tescomobile You can’t help me, I’m not the primary account holder. I have to pretend to be my wife just to get an update.

  • _sopphh96_ soph❤️‍🔥 (@_sopphh96_) reported

    @tescomobile I literally have no bars of signal and it said there were no issues in my area!

  • malla_cj colinm (@malla_cj) reported

    @tescomobile Already have and nothing but for a whole area to be complaining there must be a problem please look into it 🤷🏻

  • Calzonafan2013 CharityNess (@Calzonafan2013) reported

    @Gems2712 @tescomobile You can buy a cheap, burner phone from a store. Still not cheap though. My American service allowed me to add data and phone when I was in Europe for $10 a day

  • Aiden_Cooper Aiden (@Aiden_Cooper) reported

    @tescomobile @Tesco @Tesco I need help tracking a sim free phone order please.

  • rfj1966 RFJ💙 🇺🇦 (@rfj1966) reported

    @LinnettHill @tescomobile Had to drive round with the daughter last night so she could get the security text to log on to her Uni account. There is a bit of signal around The Hollies and George Fisher. Short walk for you 👍 have used my works phone to cal Tesco again and express my disappointment. 😱

  • rjm101163aux Richard Maunder (@rjm101163aux) reported

    @tescomobile Thank you I do HOPE you will retrain YOUR staff NOT to lie to people when buying a phone or sim card from Tesco's ?? Like YOU have already told me nothing can be done about my problem PLEASE STOP telling me to message you privately it would only be a waste of my money and time.

  • _sopphh96_ soph❤️‍🔥 (@_sopphh96_) reported

    @tescomobile I updated my phone to iOS 16 and now I have no signal whatsoever?!

  • miketazo mike patterson (@miketazo) reported

    @tescomobile worst customer service ever promised call backs on more than one occasion but not one call back I think it’s time to find another network

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

    @tescomobile The last (but 2) support person asked for 48 hours, hopefully that means it’ll be sorted tomorrow. However, it’s the fifth time I’ve been told that.
