Australia here, if that makes a difference. I've bought my parents a Galaxy J1 mini, their fist smartphone (not a bad little phone, but no flash for the camera? Never come across that before, how superbly crappy). Their current plan is for their dumbphone and includes no data allowance but is otherwise a great deal (basically unlimited calls for a tiny price), however they have wireless at home so can do all the smartphone updates etc via that. My problem is that there doesn't seem to be a way to switch off mobile data connection on the phone. I've tried several data switches from Play but they don't work, some of them saying the data can not be switched off on this device. Why is it so? Am I missing something?
