All cell phone towers seem to be aimed toward the ground.
I've flown a GA aircraft all around the lower 48, and only get a cell phone signal briefly when flying directly over a cell tower.

That said, you do get the occasional misaligned antenna or weird bounce off terrain that gets you signal midflight for a minute.
