Answer 2

The first handheld mobile phone was demonstrated by John F. Mitchell[2][3] and Martin Cooper of Motorola in 1973, using a handset weighing c. 2 kilograms (4.4 lbs).[4] In 1979, Nippon Telegraph and Telephone (NTT) launched the world's first cellular network in Japan.

Mobile phones are used for a variety of purposes, such as keeping in touch with family members, for conducting business, and in order to have access to a telephone in the event of an emergency. Some people carry more than one mobile phone for different purposes, such as for business and personal use. Multiple SIM cards may be used to take advantage of the benefits of different calling plans. For example, a particular plan might provide for cheaper local calls, long-distance calls, international calls, or roaming.

Cell phones have evolved immensely since 1983, both in design and function.Back in the early days of mobile phones, their sole use was for calling other people whilst on the move. Soon after, the ability to ‘text’ other mobile phones was introduced. Nowadays you can use mobile phones to do literally everything. From paying for your next meal to tracking your sleeping habits, the smartphone of today has almost no limits.

That’s not the only thing that has changed since the first mobile phone went on sale. Think the iPhone XS is pricey at $1,500? Well, the first mobile phones went on sale for a whopping $4,000 each! The increased demand for mobile phones has caused technology to advance rapidly, with prices continuously falling.

Modern society has always seemed to have a bit of an obsession with technology. But no single device has had as much of an impact on the world than the mobile phone.
