Teach you how to judge whether the 5G you access is NSA or SA.

This paper takes Huawei or HONOR as an example:

1. Device support

(1) The mobile phone needs to turn on the corresponding settings and the 5G switch.

(2) Enter the developer option and select SA+NSA mode.

2. Packaging support

Mobile SA is automatically opened, and Unicom Telecom hopes that the system will be automatically opened or manual customer service consultation will be opened.

Take Unicom as an example, you need to handle: 5G service (SA).

3. Query NSA or SA access rights

About mobile phone-status information-network (many mobile phones have the function of status information)

SA: the mobile network type is displayed as "NR"

NSA: the mobile network type is displayed as "LTENR"

The difference between SA and n SA:

NSA:NSA network belongs to non-independent networking, and 5G and 4G are interconnected at the access network level, with complex interconnection.

Sa: sa network belongs to independent networking.

Personal experience, SA delay is lower, saving electricity. After all, NSA is still based on 4G, so it costs a lot of electricity. With SA, the battery life of the mobile phone will be much better (compared with NSA).
