Mobile Call History : 50 years ago the first call from a mobile

Hello! Joel, I'm actually talking to you on a cellular phone. From a phone that can be carried in hand.

This dialogue is 50 years ago, on April 3, 1973, that is, on this very day, Dr. Dr. Martin Kupur, a competitor in New York, from a cream-colored Motorola phone made by himself. Joel had a wireless call with Angles.

Hearing Cooper's words, Dr. Angle seemed to fall from a cliff. Because he had no words to communicate. Perhaps his competitor, Cooper, had made a cordless phone call before him. This cellular mobile was the first phone in the world. Motorola company researcher Martin Cooper. He called AT&T's Joel Engle from a Motorola Dyna-Tac 8000X handphone he had built. At that time the weight of this mobile was 2 kg. 

Dr. Although Cooper first invented the mobile phone in 1973, it took 10 years to reach the market. A lot of research was done about the phone and later its sales started in 1983. When the sale of mobile phones started in New York City, USA, its market price was 3,995 US dollars, i.e. 10,000 US dollars according to the current market price.

At that time, the weight of the mobile was reduced to 1.1 kg. This 9-inch tall Motorola mobile phone was only used to pick up the phone and talk. There were no facilities like taking pictures and GPS system like now. There was no facility to insert SIM card.

90-year-old Dr. Cooper laughs and says, "Do you believe it?" Now we are developing phone based on car and later it will help us for 100 years for home and office work.'

The use of GSM started in 1987 with the help of digital technology in mobile phones. In 1992, the facility of SMS became available for the first time. It started with texting for the first time in the UK.

The mobile phone with a camera was invented by the Samsung company with the Samsung SCH-V2000 phone. At this time there was a facility to take up to 20 photos, but no one could be sent. The process of sending photos taken only by the J-SH04 model phone to other mobile phones was started. Both these mobile phones were invented in Asia.

The Nokia 9000 was the first mobile phone to be connected to the Internet. It was released in 1996. The iPhone was launched in 2007. There are currently 6.92 billion smartphone users in the world, while 73 percent of households in Nepal have access to the Internet.
