In 1979, the merger of Nokia and Salora 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.
As for the Mobira Senator, it was launched in 1982 and was marketed as a phone for in-car use. Sure, you could carry it around, although its weight of 9.8 kg (22 lb.) made that a challenging task. Today, the Mobira Senator is one of the rarest cell phones that have ever existed, which is not surprising given its age.
