As far as I can tell, you can use WiFi without using Data. The only problem is that in order to make sure you are using only WiFi you have to turn off your data. Turn off the Mobile Network from the Manage Connections and you will be able do everything with WiFi, but you will not get any phone calls or text messages.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
