How to set up the voice broadcast of Guizhou rural credit cooperatives?

"After opening, enter the mobile phone number (for example, Huawei GRA-CL 10, version number: GRA-CL1092B366, system version number: EMUI system 4.0. 1), reset the login password first, log in again after setting it, set permissions to allow, and set voice opening. Have the customer scan the code to see if voice broadcasting is available. If there is, you can use it. If not, it depends on the permission setting. In addition, it should be noted that the rural credit e-purchase can only be broadcast by voice. If you turn it off, you will not be able to receive voice messages. So even if the phone locks the screen, let it be in working condition. "
