    @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?

  • 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

    Hi @tescomobile can you help? My SIM card stopped working and o was given a new one in your Poole store - I've put it in my phone, how long before my phone works again?

  • pamelaallison66 Pamela Allison (@pamelaallison66) reported

    @tescomobile shocking service at your Irvine store. After trying to recommend a friend online & it not going through we went in to store. Guy had absolute no interest and most unhelpful. We left…

    @tescomobile poor experience of in store supposedly being transferred to cheaper contract. Misled during signing up process and not told that for the interim period to next bill I would only have 8gb rather than the unlimited data I had before and would have on new contract.
