I will be staying at my mothers home and I want to know how to use my iPad and connect to the Internet but my mother has no internet connection. I assume I will need to instal a SIM card, can anyone recommend a good service provider that has a pay as you go plan that is reasonable. For me to make FaceTime calls for a week whilst not connected to a local home wifi network. There ar no free local hotspots I can use where she lives.
