Introduction of Mobile phone
A mobile phone is a telephone that can make and receive calls over a radio frequency carrier while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, so mobile telephones are often called cellular telephones or cell phones. In addition to telephony, modern mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones.

An electronic telecommunications device, often referred to as a cellular phone or cellphone. Mobile phones connect to a wireless communications network through radio wave or satellite transmissions. Most mobile phones provide voice communications, Short Message Service (SMS), Multimedia Message Service (MMS), and newer phones may also provide Internet services such as Web browsing and e-mail.
The mobile phone -- also known as the cellphone -- has infiltrated our daily lives, becoming the quintessential communication device. The mobile phone has developed over time, becoming more useful with every new capability. Most versions today can fit into your back pocket with ease. Much more than a phone, modern-day mobile phones help keep us organized and connected with the many features they offer.
