    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 😡

  • 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?

  • 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?

  • charlielford charlotte ford. (@charlielford) reported

    @tescomobile I was told by head of complaints I would receive two months free line rental after you let me without service for a week, didn’t charge me for it last month but have charged me the full months payment this month. always says one thing and does another with you!

  • Alan_b1 Alan Blakely (@Alan_b1) reported

    @tescomobile There was an outage but fixed now

  • finnigan1971 Michael Finnigan (@finnigan1971) reported

    @tescomobile anybody else think that Tesco Mobile Website and support is rubbish- how can it be this difficult to place an order on line??

  • BenjaminLegget3 Ben Leggett (@BenjaminLegget3) reported

    @tescomobile I tried that link but it just got me through to some random that didn't help. The phone I've ended up with is unusable, it freezes constantly, it's slow and insufferable, it makes me miss calls as it locks up and the screen locks on and off etc every two seconds.
