At what altitude does cellphone service cease to operate?

Asked by john65pennington (29283points) June 16th, 2011

We’ve all been in an airplane that is about to take off. On the ground, cellphone service operates normally. Question: at what altitude does regular cellphone service cease to function? 5,000 feet? 10,000 feet???
