How well do cell phones really work?

My niece graduated NYU a couple weeks ago, and standing outside Madison
Square Garden, using a cell phone, I could not reach her mother (who had
the tickets***), only her voice mail. She was probably inside by then.

But I could reach my niece, who was also inside by then.

Her mother could not reach me, although I later found 4 messages from
her from that time period on my voice mail. But she could reach her
daughter at the same time.

Her daughter could reach both of us.

How is this possible?


In addition to the other reply, I have found that much depends on network
usage at any given time. You could be crowded out when everyone tries to
use a limited resource at the same time.

This is one reason carriers are in the process of adding WIFI coverage, in
addition to regular cell coverage. If you are within WIFI coverage, they
can route you through the wired system without having to use their precious
cell bandwidth (or even if you are nowhere near cell coverage).

In NYC AT&T has a lot of issues. Verizon does not.
