3G service
It is a wireless communications service, and the 3G symbol refers to the English term (3Generation), that is, the third generation of digital communications, which depends on the idea of developing the speed and performance of communication with the Internet, by increasing the data transmission capacity between the different network frequencies, so that it is read from Before the network's antenna towers, which in turn convert it to cellular telephone devices, this service differs from the previous services (generations), which are 1G, 2G, in that it has a broader broadcast range, and the ability to transfer the nature of data in less time than previous services.
The advent of 3G service
The emergence of the 3G service for the first time dates back to a group of Japanese companies, which obtained a license to use it officially in 2001 AD, and then it was linked to the WCDMA digital band, which spread on most cell phones as a sign that it contains the possibility of connecting to the third generation network. As for the spread of the 3G service Globally, with individuals being able to use it on their mobile phones, it was between 2005 and 2006 AD, to cover almost all countries of the world with a wide network.
In 2006, the 3G service was developed, and it was launched at a new frequency, called HSDPA, but it did not include most of the countries of the world until after the telecom company installed devices to strengthen the transmission and reception of network frequencies within its range, and after a group of years HSDPA technology was developed, to increase the speed of the third generation many times over. The previous speed, and this development was called the term HSPA +, so that this digital service covers all countries of the world.

There are a range of applications provided by the 3G service to individuals and all business sectors, including:
Provide visual communication
It is a modern communication method that was previously used with previous generations of the digital network, but it was suffering from slow communication, with unclear sound and image, and with the advent of the third generation network, and electronic applications for modern cellular phones, it contributed to the development of the idea of visual communication, which is no longer It is limited to the presence of a computer with a camera connected to it, but it has become possible to communicate using a cell phone that has a front camera, so most telecommunications companies have sought to provide visual communication service, as one of the advanced third generation services.
Fast internet connection
The third generation network provided a fast connection with the Internet, by providing a direct connection with the network, and this is a development compared to previous generations, through which communication with the Internet was expensive, and it needed a set of tools in order to secure the appropriate connection between the user and a service provider Internet.
Providing a range of public services
The third generation network contributed to the provision of a range of public services, as it helped in the application of digital information technology in a number of practical and educational fields, which contributes to the ease of performing many tasks that in the past required effort and a long time to fully implement them.
