ges and Disadvantages of Using A Cell Phone

Until the 1800s people used letters for communication. But this way was very slow, and people couldn’t contact each other in emergency situations. There was also the possibility of letters being lost. But after the invention of the telephone in 1876 by Alexander Graham Bell, it became easier for people to communicate. Then in the 1970s, the cellular phone was invented. It brought many advantages into our lives. However, although cell phones brought many benefits into our lives, they also have disadvantages.

The most important advantage of cell
phones is that they can be used almost everywhere without cables or electricity. By using a mobile phone, you can communicate with anyone whenever you want and wherever you are. Besides this, if there is an emergency situation, mobile phones can be useful. Furthermore, you can get access to the Internet by using a cell phone. These days, the world’s most common means of communication is SMS. Cell phones include this system, so in this way you can communicate with someone more cheaply than by normal calling.

In contrast, cell phones have some disadvantages. For example, cell phones spread electromagnetic waves. And these electromagnetic waves cause important health problems like cancer. Additionally, cell phones often affect the electronic systems used by equipment like cars, ABS (automatic brake system), and computers. This can cause big problems, such as accidents.

To sum up, cell phones not only have advantages, but also they have disadvantages. Mobile phones make our lives easier. But at the same time, they cause some important problems in our health.
