A mobile phone (cellphone, etc.) is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone (landline phone).
Cell phones are being carried by almost everyone around the world including children, teenagers, adults, as well as grandparents.
Phone companies are one of the fastest growing businesses on the market. This is because technology is blooming.
Cell phones are small and easy to carry around.
Modern digital cell phones can process millions of calculations per second in order to compress and decompress the voice stream.
Cell phones have full duplex, meaning you can use one frequency for talk and other frequency for listening.
Other advantages of cell phones are that you can store information, make task or to do lists, keep track of appointments, and set reminders.

Cell phones have great influence in our everyday life and are convenient to have around.
Cell phones are a faster and more effective way to transfer information.
Cell phones physically have non-repairable internal parts that can corrode.
For example if a cell phone gets wet, it may damage the internal parts.
Extreme heat in a car can damage the battery or the cell phone electronics and extreme cold may cause a momentary loss of the screen display.
In the tall building rage, it is hard to gain service because the cell phone might not communicate well with the cell towers .
There are reasons to think that cell phones may cause cancer of the ear or brain tumors.
The more an individual uses cell phones and the greater the number of years used by the person, the greater the risk of brain tumors.
However, there has been doubt of phone companies that there are no links to cancer even though the phones radiations do not have any connection to the electrical activity
