  Mobile Phone
A mobile phone is a portable electronic device which behaves as a normal telephone whilst being able to move over a wide area (compare cordless phone which acts as a telephone only within a limited range).
Mobile phones allow connections to be made to the telephone network, normally by directly dialing the other party's number on an inbuilt keypad.
In many affluent countries, mobile phones now outnumber land-line telephones, with most adults and many children now owning mobile phones and is not uncommon for young adults to own simply a cell phone instead of a land-line for their residence, even in the U.S. where mobile phone use is less prevalent than other industrialized countries.

 Nordic Mobile Telephone - Wikipedia, the free encyclopedia
It was specified by Nordic telecommunications administrations (PTTs) starting in 1970, and opened for service in 1981 as a response to the increasing congestion and heavy requirements of the manual mobile phone networks: ARP (150 MHz) in Finland and MTD (450 MHz) in Sweden, Norway and Denmark.
NMT is based on analog technology (first generation or 1G) and two variants exist: NMT-450 and NMT-900.
NMT had automatic switching (dialing) and handover of the call built into the standard from the beginning, which was not the case with most preceding car phone services, such as the Finnish ARP.

 Nordic Mobile Telephone NMT
NMT (Nordisk Mobil Telefon or Nordisk Mobil Telefonkruppen, Nordic Mobile Telephony in English) is a mobile phone system that was created in 1981 as a response to the increasing congestion and heavy requirements of the ARP mobile phone network.
