The maximum range for GSM is about 25 miles. That's for technical
reasons involved with sharing one cell with several handsets (and the
speed of light back and forth) rather than the radio waves getting too
weak. Of course, on land things tend to get in the way, and cells are
usually much smaller anyway.
