Not at all, flying at low level over the most densely populated cell phone towers in the USA, you get phone signals on transatlantic flights once you get to 3500'...This world's a stage eh? I wonder what happened to 4 planes worth of people who never made it home? Where they transported to Dulce or some other program/base? The cellphone calls from passengers at the time are also questionable given the technology then.
how do I know?...
years of flights hearing text messages and ringing, as forgetful passengers (and crew) frantically switching to airplane mode. Don't forget back then we had even longer range/bigger cells.

But please do you own "internet research" (sic).
Better still ask a friend to send a text message while you are over Greenland and take your phone off "airplane mode".
See when your text comes in, make sure it is on silent/vibration mode, as you'll be breaking loads of US aviation and telecommunications laws. Note phones 25 years ago had greater range transmission and reception than today.
Don't worry about the planes navigation/control systems, they are hardened to prevent any interaction with mobile phone frequencies... f'hink about it.... if I was wrong planes would be crashing/going off course every day..
You're Welcome.
