Before the Invention
Cell phones have changed since being invented
The world was very different before the cell phone was invented. Many abilities available to us now such as text messaging, calling to and from almost anywhere, and instant entertainment were not even considered before. Now many people just take them for granted.
Previous Technology
An example of a handheld radio
Before cell phones, there was not an absence of cellular technology. One example of these early technologies are radios. They allow people to stay in touch as long as they are nearby. You can communicate between multiple people with units instead of one-on-one, like a cell phone.
