    @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?

  • 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?

    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

  • Saeed_Ahmed02 Saeed Ahmed (@Saeed_Ahmed02) reported from Victoria, Wales

    @tescomobile needs to better support the Google Messages app. I quite like using the Google Assistant to send texts and it always comes back saying failed

  • TRHComposer Thomas Richard (@TRHComposer) reported from Cardiff, Wales

  • 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

    Anyone use Tesco mobile? Are they any good? If anyone could let me know would be great. #Tesco #TescoMobile #Help

  • SimonGCutmore Fr. Simon Cutmore SHS (@SimonGCutmore) reported from Rickmansworth, England

    A bit peeved at @tescomobile. Tried getting @MatthewCutmore4's PAC code online. No joy. Tried phone, no one answers. We have four contracts with you. It really shouldn't be this difficult to leave the network

  • darcydyster Jane Dyster (@darcydyster) reported from Tolleshunt D'arcy, England

    @tescomobile further to my earlier tweet have looked at getting new phone but will have to pay huge fee! I just need a reliable phone, and can’t be without phone whilst my other one is looked at. Feeling very frustrated, please help

  • Watto_Clare Clare Watson-Spence (@Watto_Clare) reported from Coalville, England

    Can anyone help with 20 data dongles for a school I’ve worked closely with. The free WiFi/data would allow these families to access on line learning for lock down. Would be a loan until they return to school! Please try and help! Thank you xx @virginmedia @tescomobile @O2

  • say2simon Simon D (@say2simon) reported from Barnsley, England

    @averagejo10 @tescomobile Yes thanks. Sadly no help and long queue times. Distressed elderley parents who don’t understand it’s an auto dialer. 60 calls, last three digits always changing grrrr

  • purplecircle70 sandra thelwell (@purplecircle70) reported from Shotton, Wales

    @tescomobile can you help sons phone out of contract and now broken want to cancel contract. Cant do online and struggling to get hold of Tesco via phone. Thanks

  • leon_dave_smith Leon Smith🇬🇧🇪🇺❄️ (@leon_dave_smith) reported from Broxbourne District, England

    @tescomobile I am being charged £59 for 20gb a month and for a almost two year old phone, where I can buy iPhone direct from Apple and get a sim only deal for unlimited calls, texts and data for less than you are charging a valued customer, I don’t understand your pricing
