On March 10, 1876, 150 years ago, the first telephone call was made, a milestone that forever changed our way of communicating. “Mr. Watson, come here, I want to see you,” was the phrase that the Scottish inventor and scientist, Alexander Graham Bell, conveyed to his assistant, Thomas Watson, just three days after patenting his invention, which progressively relegated the telegraph, used since 1844. Quickly, that system became popular to become a mass communication medium that we all carry in our pockets today.

We review some of the first mobile phones that integrated functions that now seem ordinary but were revolutionary. Originally, their technology was very limited, and they had very different dimensions than most current commercial models.

Both companies and public entities will be prohibited from using a mobile number to make commercial calls. The objective of this measure, included in a recently approved ministerial order of the Spanish government, is to avoid identity theft scams that are carried out through calls or SMS.
