How to open Unicom's 5gsa business? What is 5GSA?

During the commercial trial of Beijing Unicom SA network, users who meet the opening conditions and have needs can open it through Beijing Unicom business hall and 100 10 hotline.

1, users who open VoLTE service.

2. Open directional free-flowing products in the province.

Tips: In addition to the above businesses, there are other businesses that cannot be handled. Please consult local customer service for details.
