In 1973, a telecom engineer from the United States made the first mobile phone call in public. The call happened on a street in Manhattan using a heavy Motorola phone. This phone later became the first one sold to the public. Mobile phones became common around the world. A report in 2023 said that 60% of people already had mobile internet. More than 4.6 billion people now use smartphones. Phones are used not only for calls but also for online access and entertainment. In many countries, phones are a symbol of being connected.

Today, mobile phones are more advanced and powerful. Experts believe that future phones may help check health and use body energy. This can be beneficial in hospitals. However, there are also challenges. Some teachers say too much screen time can affect learning and social skills. Because of this, several states in the U.S. have banned phones in schools. Still, some educators say phones can contribute to learning. The mobile phone is a great invention with unrealized power for the future.
