That would be true if it wasn't for the fact that the cell towers are pretty directional and don't waste huge amounts of energy by pointlessly blasting radio waves towards the sky.
From two miles away (horizontally), you could get a perfect signal. At just a few hundred meters directly above the cell, you'll get nothing.
