Making a cell phone call in a jet flying over 8000 ft is virtually impossible...and data exchange impossible above 8000 ft.

As for cell phones and aircraft (yet again), hands up all those who have flown between say western europe and the far east and never, ever found the likes of a "welcome to CIS telecom" ( or something similar) text on their phone on arrival in NRT....
Just for a factual record: My cellphone, unintentionally left ON, inside my luggage stowed in the forward section of B747 main deck, had recorded 3 "welcome messages" from a Bangladesh telecom, while traversing the country at FL330.
