Hi there, I have an ipad which only has wifi and been thinking of getting the one which has wifi and cellular. I will be using it as a gps for my flying and was wondering if you guys know if it is possible to get the cellular one but not to get a contract and still be able to access google maps or one of my flying apps (foreflight)? So saying I'm flying to the US and of course don't want to get overcharged because my data is on, so I turn it off. Will the ipad still know where I am? So could it still keep track of me while en route? I hope you guys know what I mean and hopefully anybody can help me. Thanks!
