First mobile phones

The technologies that preceded modern cellular mobile telephony systems were the various "0G" pre-cellular mobile radio telephony standards. Nokia had been producing commercial and military mobile radio communications technology since the 1960s. Since 1964, Nokia had developed VHF-radio simultaneously with Salora Oy. In 1966, Nokia and Salora started developing the ARP standard (which stands for Autoradiopuhelin, or "car radio phone"), a car-based mobile radio telephony system and the first commercially operated public mobile phone network in Finland. It went online in 1971 and offered 100% coverage in 1978.

In 1979, the merger of these two companies resulted in the establishment of Mobira Oy. Mobira began developing mobile phones for the NMT (Nordic Mobile Telephony) network standard, the first-generation, first fully-automatic cellular phone system that went online in 1981.In 1982, Mobira introduced its first car phone, the Mobira Senator for NMT-450 networks.

The Mobira Cityman 200, Nokia's NMT-900 mobile phone from the early 1990s.

Nokia bought Salora Oy in 1984 and now owning 100% of the company, changed the company's telecommunication branch name to Nokia-Mobira Oy. The Mobira Talkman, launched in 1984, was one of the world's first transportable phones. In 1987, Nokia introduced one of the world's first handheld phones, the Mobira Cityman 900 for NMT-900 networks (which offered a better signal, yet a shorter roam). While the Mobira Senator of 1982 had weighed 9.8 kg (22 lb) and the Talkman just under 5 kg (11 lb), the Mobira Cityman weighed only 800 g (28 oz) with the battery and had a price tag of 24,000 Finnish marks (approximately €4,560). Despite the high price, the first phones were almost snatched from the sales assistants’ hands. Initially, the mobile phone was a "yuppie" product and a status symbol.

Nokia's mobile phones got a big publicity boost in 1987, when Soviet leader Mikhail Gorbachev was pictured using a Mobira Cityman to make a call from Helsinki to his communications minister in Moscow. This led to the phone's nickname of the "Gorba".

In 1988, Jorma Nieminen, resigning from the post of CEO of the mobile phone unit, along with two other employees from the unit, started a notable mobile phone company of their own, Benefon Oy (since renamed to GeoSentric). One year later, Nokia-Mobira Oy became Nokia Mobile Phones.
