Recently, China Unicom announced to shut down the 2g and 3g signals to speed up the construction of the 5g network and improve the user experience. This move will help to promote the construction of China's 5g network, realize digital transformation, and bring users a better network experience.

What are 2g, 3g and 5g networks?

2g network is the first generation of mobile communication technology, which can realize voice calls and simple short messages. 3g network is the third generation mobile communication technology, which can realize high-speed data transmission and multimedia communication, such as video calling and Internet access. 5g network is the fifth generation mobile communication technology, which can realize higher data transmission, lower delay and wider connection, and will provide better support for the development of emerging technologies such as artificial intelligence and Internet of Things.

Why turn off the 2g and 3g signals?

With the continuous development and popularization of 5g technology, 2g and 3g networks have gradually become obsolete, which cannot meet the needs of modern people for high-speed and high-quality networks. At the same time, turning off 2g and 3g signals can release spectrum resources, provide more space and resources for the construction of 5g networks, and accelerate the development and popularization of 5g networks.

How to turn off 2g and 3g signals?

Turning off 2g and 3g signals requires some technical operation. The following are the specific steps:

Back up mobile phone data to avoid data loss.

Go to the phone settings and find the "Mobile Network" option.

In the "Mobile Network" option, find the "Preferred Network Type" option.

Set the preferred network type option to 4G/5G.

Save the settings and restart the phone.

The above operation is only applicable to some mobile phone brands and models, and the specific operation methods may be different. Users should pay attention to backing up data during operation to avoid data loss.

What's the impact of turning off 2g and 3g signals on users?

Turning off 2g and 3g signals has relatively little impact on users. For users who have already used 4g and 5g networks, turning off 2g and 3g signals will not affect their normal use. For users who are still using 2g and 3g networks, turning off 2g and 3g signals will make them unable to use voice calls and short messages normally, so they need to upgrade their mobile phones or replace their SIM cards.
