Anatel prepares to turn off 2G and 3G networks in Brazil; see what changes

A Internet Mobile in Brazil has come a long way since its introduction in the country. Since the arrival of the first cell phones, technology has evolved significantly and the obsolescence of older networks, such as 2G and 3G, is an increasingly present reality today.

2G, which brought the ability to send text messages and make calls to mobile devices for the first time, was a milestone in the 1990s.

However, its speed and data capacity limitations quickly became evident as demand for internet access in mobile devices increased.

3G, a natural evolution of 2G, brought significant improvements, such as the ability to browse the web and use applications on mobile devices.

However, today, 3G is also becoming obsolete.

End of old networks

Currently, the National Telecommunications Agency (Anatel) is conducting a comprehensive survey to assess public opinion and telephone companies’ perspectives on the possibility of shutting down 2G and 3G networks in Brazil.

This initiative represents a significant change in the mobile communications scenario in the country, being motivated by a series of factors that highlight the growing disuse of these networks.

Why shut down?

One of the main reasons for the shutdown of 2G and 3G networks is the limitation of compatible devices. Currently, only older cell phones are capable of connecting to these networks.

As most consumers acquire modern smartphones with 4G and 5G support, 2G and 3G usage is drastically decreasing. This means that keeping these networks active represents a significant cost for telecommunications companies, without meeting substantial demand.

Another critical factor is the issue of maintenance. 2G and 3G networks require continuous investment in infrastructure, equipment and technical support. With the increasingly less frequent use of these technologiesthe costs associated with its maintenance are becoming less and less justifiable.

Telecommunications companies’ financial and technical resources can be more effectively directed toward enhancing 4G and 5G networks, which are essential to meeting growing demands for high-speed data and mobile services.

Furthermore, the mobile device market is rapidly migrating to smartphones compatible with 4G and 5G networks. The wide availability of these devices makes migrating to these networks a natural choice.

Most modern apps and services are optimized to operate at 4G and 5G speeds, providing a safer experience for users.

The shutdown of 2G and 3G will allow communications companies to focus on providing high-quality connectivity and more advanced services.

However, it is important to highlight that the transition to 4G and 5G networks must be carefully managed to ensure that all parties are properly informed and that there are no significant disruptions to services for those still using the older networks.

Anatel is aware of these concerns and will work in collaboration with telecommunications companies to ensure a smooth transition without major losses to the connectivity in the country.
