I found that I was traveling around more and more often, especially as part of my job as chief salesman for my company, and I was sometimes finding that my family could not get in touch me. I had a cell phone, but sometimes the cell phone did not work, especially in some far out places, and it was because of this that I decided to look at buying one of the many Alphanumeric Beepers that are now available. They are a very simple device which essentially tells you that someone is trying to get in touch with you, but they really are helpful in keeping in communication with people that you do not want to lose touch with.
