    @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?

    @tescomobile Like to thank you for the help you gave in requesting a free SIM card for my Nokia 216, all I need to get now is a micro SD card, so that I might capture the odd selfie. I will request an e-TopUp card the sooner I'll get the number from the SIM card I've requested
