Plus, most people don't just want to make calls on their cell phones,
they want to be able to receive calls. So, as soon as you turn on your
cell phone, it does a scan for the most powerful (closest) signal. Once
it finds it, it sends out your phone id to that tower, and it is entered
into a database, so when somebody calls you, that call can be routed to
the tower that your phone is now listening to.
