have heard that the service providers have problems charging the users because the phone will pull in multiple cells at the same time to relay the signal.
When cellphones first came out, the service providers discovered one phone at 39,000 feet could utterly confuse the cell-transmitter-computers by logging on--every few seconds--from 50 cities simultaneously.
So they went to FCC and said "Stop them!"
And the FCC went to the FAA and said "Simon Says Stop Them!
And the FAA said "Stop!"
That is / was the first concern and then everybody climed on the bandwagon.

This is what happened when I overflew Baghdad the other day
