    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

  • 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?

    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 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 😡

  • jatsy768 Jess (@jatsy768) reported

    @tescomobile I've had no 4g for weeks, it just says H+. When I check of there are any issues it just says it's busy, but it's always been busy, I live in a city??

  • pickled_tinker Grody🔞 (@pickled_tinker) reported

    @tescomobile **** all. Because everytime they up my bill, I use Ofcoms General Conditions 9.6 to early terminate my contract under material detriment. I then go hunting for a better deal and repeat the following year.

  • brushhead71 Robert Wilson (@brushhead71) reported

    @tescomobile The website is refusing to take my email address because it already exists. I was a customer before and want to come back. I cannot log in with my old credentials.

  • xenoblast Xeno (@xenoblast) reported

    @tescomobile You don't run your own hardware infrastructure, do you? So if you re-sell a service, your source can also sell it at your price.

  • LutonEye Ｌｕｔｏｎ Ｅｙｅ (@LutonEye) reported

    @Wandsworth3 @EE @tescomobile The trouble is, EE will still raise their prices by RPI or CPI and claw their money back that way. I am happily tied in.

  • winkleink Albert Hickey (@winkleink) reported

    I've a contract with @tescomobile that includes payment for the phone and a separate monthly rolling agreement for Usage. As their current plans for usage are better on sim-only I asked to cancel monthly rolling and go on 24m SIM only for usage.

  • jatsy768 Jess (@jatsy768) reported

    @tescomobile It's happening with a few of my friends, all either on Tesco or gifgaf (both use o2) in & around Gloucester, I don't think my phone is the issue

  • XenithLive Xenith (@XenithLive) reported
