    @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?

  • 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?

  • 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 😡

  • 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?

  • 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 hi, I had a technician find an issue with my phone today which was to do with the 4g calling. He said its not properly registered and the signal is far poorer than it should be so suggested I speak to yourselves.

  • burge1985 James Burgess (@burge1985) reported

    @O2 - I would like to make a complaint. I'm a victim of identify fraud and your fraud department have taken over 2.5 months to respond (I am still waiting!). @VodafoneUK and @tescomobile took 10 days to close the case from contacting them. What is taking so long to respond to me?

  • SamthaJay Samantha (@SamthaJay) reported

    @O2 My renewal is due but looks like I can get a better deal with @tescomobile - who use your network?! I don’t really want to leave but need to look for the best value…

  • JAMCaved Joey (@JAMCaved) reported

    @Tesco @tescomobile buy a handset via Tesco mobile, it will magically tell you it’s nothing to do with them when they cancel the order and don’t refund, because that’s from Tesco direct…WHO DON’T EXIST OR HAVE A HELPLINE! You’ve done this to us twice. Time for small claims court

  • Exposed62 Exposed6 (@Exposed62) reported

    @FOS_Objectors Yes I definitely will @financialombuds you never help with @tescomobile they need to be SHUTDOWN

  • Emzbradoxx Emily (@Emzbradoxx) reported

    @tescomobile hi, my phone is not loading anything on the internet. The wifi works fine on my laptop but my phone isn’t (I didn’t buy my laptop from Tesco but I did buy my phone from here). My wifi is virgin media. Is there anything I can do to fix it? Thanks

  • wonderlandwidow Clare Ruscoe (@wonderlandwidow) reported

    @tescomobile Still no contact...... and I am £55 out of pocket after being a loyal customer for years this is not really sitting well!!

  • greyed_out Greyed Out (@greyed_out) reported

    @tescomobile Still not receiving log in PINS but I will discuss tariff change with Live Chat when today's service issues with transmission of texts have been resolved.

  • ClassifiedPrize FREE Online Classified Advertising & Prize Draw (@ClassifiedPrize) reported

    @greyed_out @tescomobile Thanks for sharing - I thought it was just my phone. I will now take the time to follow-up (BTW - my phone is on now contract so not a PayG issue).
