The Ministry of Industry and Information Technology has made it clear that the SA function will be turned on by default for new 5G mobile phones

5G mobile phones are divided into NSA and SA dual modes, and only 5G SA networks can provide the most complete 5G experience. Recently, Liu Liehong, Vice Minister of the Ministry of Industry and Information Technology, said that the 5G SA function will be enabled by default for new 5G mobile phones.

At yesterday's 2021 World Telecommunication and Information Society Day Conference, Vice Minister Liu Liehong stated that new 5G terminals will have the 5G independent networking (SA) function enabled by default, accelerating the maturity of new 5G-based consumer terminals and promoting the large-scale application of the independent networking model.

Liu Liehong said that China has taken the lead in 5G development, with a total of more than 819,000 5G base stations built, accounting for about 70% of the world's total; the number of 5G mobile terminal user connections has reached 280 million, accounting for more than 80% of the world's total.

Regarding the issue of 5G SA, the three major operators have previously begun to require that the SA function be turned on by default. China Mobile requires that from March 1, the SA function be turned on by default in terminals, and setting the SA switch is not allowed.

NSA and SA are two network standards in the 5G network. The former still requires a 4G core network and is seen as a transitional option, but 5G NSA cannot connect to SA base stations, which will result in 5G single-mode mobile phones that only support NSA being unable to access the Internet through 5G.

In contrast, SA is connected to the 5G core network, has more powerful functions, and is the development direction of 5G.
