How to switch 5GSA mode on mobile phone?

The mobile phone cannot connect to the 5G network, and the location may not be covered, and there is a 5G signal.

Because if there is no 5G signal, even if the mobile phone supports 5G network, it will not be able to connect.

Hello, among the 5G mobile phones on the market, some mobile phones support both NSA and SA (usually described as "5G dual-mode mobile phones" on the market), and a small number of mobile phones only support NSA (usually described as "5G single-mode mobile phones" on the market, or "dual-mode" mobile phones basically only support NSA). Currently, all mobile phones that support SA support NSA.

Now you can't use the 5G network if you buy a 5G card and a 5G mobile phone, because there are no 5G base stations in most areas, and the network you use is only 4G+, not a real 5G.

When the mobile phone switches to 5G mode, you first need to have 5G network coverage in this area before you can switch, otherwise it will be used by heaven to switch over.

SA is not a real 5G, I guess you don't understand what is real, this is the real 5G. There are two main reasons why your phone does not have a 5G network, one is that you can't cover it there. The second is what I just said.

SA is, that is to say, the meaning of 4G + hybrid network, the real pure 5G network is NSA, which is currently slowly opening up, ** is also very expensive, 300 to 600, this is the real 5G network, you can slowly understand. If you want to really get started with 5G, you need to use NSA SA, not SA mode.

When the phone switches to 5G mode, you can find the network settings in the settings.

You can check if there is a product manual or if there is any relevant guidance.

You can go into the phone settings to find out and see if they should all be operated in the phone settings.

1) Batch activation mode: The 5G SA service mode for existing SA end users is activated in batches in the background. Users who have been activated in batches in the background must meet the conditions of [5G terminal ** user], [VoLTE has been activated], [not subscribed to national directional traffic products], [not subscribed to provincial directional traffic products], [non-2i users], [not subscribed to ESIM-1 dual-terminal services], and [not subscribed to Minji other mutex policies].

Mobile users who have SA terminals and have SA functions enabled meet the requirements of "VoLTE has been activated", "has not subscribed to national directional traffic products", "has not subscribed to provincial directional traffic products", "non-2i users", "has no eSIM No. 1 dual-terminal service", "does not subscribe to VPDN" and "does not subscribe to other mutually exclusive policies" under the SA network.

Mobile communication continues the development of a generation of technologies every decade, and has gone through the development of 1G, 2G, 3G, and 4G. Every generational leap and every technological progress has greatly promoted industrial upgrading.

And the economic community will develop.

From 1G to 2G, the transition from analog communication to digital communication has been realized, and mobile communication has entered thousands of households. From 2G to 3G and 4G, the transformation from voice services to data services has been realized, and the transmission rate has increased by hundreds of times, promoting the popularization and prosperity of mobile Internet applications. Currently, mobile networks.

It has been integrated into all aspects of social life, profoundly changing people's communication, communication and even the entire way of life.

Performance refers to the standard.

2.The air interface latency is as low as 1 ms, which meets the requirements of autonomous driving.

Real-time applications such as telemedicine.

3.It has the ability to connect millions of square kilometers of devices to meet the communication of the Internet of Things.

4.The spectral efficiency is more than 3 times higher than that of LTE.

5.Continuous wide-area coverage and high mobility under the user experience.

The rate reaches 100 Mbits.

6.The traffic density reaches more than 10Mbps m2.

7.Mobility supports high-speed movement of 500 km h.

Different from 4G, the 5G era has two networking options, NSA and SA, and the key difference between the two is the leak-free 5G core network. So how do Huawei phones switch 5GSA mode?
