Question

cual es la historia del telefono en ingles

Answer 1

It was a popular service because it was extremely expensive, but was operating (with technological upgrades) from 1946-1985.

On April 3, 1973 is the first call from a mobile phone, Motorola's manager, Martin Cooper. He went to his biggest rival in the sector, Joel Engel, Bell Labs, AT & T, and made from a street in New York.1

In conclusion, the mobile phone is made portable when the project culminates Motorola DynaTAC 8000X, which is officially launched in 1984, the year he began to market it.
