I'm not interested in using mine, I'm just curious about it.
Is it possible to use it, and if so up to what height?
I'm guessing this varies given your location, so if you're over the middle of the Atlantic you're not going to get service but if you're flying over a populated city you may?
Also, would it have been possible to use them in the not too distant past but not now, because I've been told that older cell phones used to be a lot more powerful, but now aren't to comply with emissions. (I'm not sure if this is true, I've only read it in one place, so if someone could verify this then I'd be grateful)
Thanks!
