• The history of mobile phones charts improvements to communication devices which connect wire lessly to the public switched telephone network.
  The second world war made military use of radio telephony links, Hand-held radio transceivers have been available since the 1940s. Mobile telephones for automobiles became available from some telephone companies in the 1940s.

• The advaces in mobile telephony can be traced in successive generations and its successor Improved Mobile Telephone Service.

A mobile phone is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area.
In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access,business applications, gaming and photogreaphy.

Mobile phones are used for a variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in the event of an emergency. Some people carry more than one  cell phone for different purposes, such as for business and personal use.
