The invention of the first mobile phone was on April 3, 1973, and was from Motorola. At the time, the cost of the phone ran at $3,995.
Mobile rigs did not use the telephone network and users could not dial out to standard telephone numbers. The first mobile phone call was made by a truck driver as an experiment in the summer of 1946 from a phone weighing close to 80 pounds. The experiment was considered a success but mobile telecommunication technology was far from commonplace. By 1948, wireless telephone service was available in almost 100 cities.
