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). Most modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are often also 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

Two billion people on the planet use cell phones, according to James Katz, professor of communication at Rutgers University. In fact, there are more cell phone subscribers in the United States than there are people, according to an October 2011 study, underwritten by CTIA, the International Association for the Wireless Telecommunications Industry. Cell phones have become so ubiquitous in our culture that Dr. Katz teaches a class on the social aspects of mobile communication. Smartphones, PDAs and other similar devices present the user with a variety of ways to communicate with the touch of a finger.
Many Americans use their cellphones to communicate via the internet. Mobile internet capability allows them to check into social media websites, such as Facebook and Twitter, read communications from their friends and colleagues and send quick replies. At times, the communication isn’t text, but a photo, completely removing the need for words to convey a response, feelings and even location. Cell phones with broadband capabilities are also frequently used to communicate with others via email
Where the land line telephone somewhat took the place of written communication when it became commonplace, the cell phone and its texting capability sees Americans communicating, again, with the written word. The difference today, though, is that where once eloquence and verbosity were considered social graces, brevity now reigns. A different “language,” composed of acronyms, and now known commonly as text-speak, began online in the early days of email and online chat rooms. An even more abbreviated form spread with the advent of the personal pager, which only allowed seven characters -- a phone number -- to be entered. Text speak was refined with the widespread use of the cell phone, which initially allowed up to 160 characters.
