Open 360 Security Guard and enter its functional interface. Click "Mobile Assistant" to enter the interface between mobile phone and computer.

Choose the connection method for connecting the computer, or choose the data cable connection, or choose the wireless connection (if there is no data cable or want to connect wirelessly, please search and refer to "How to connect the computer wirelessly with a mobile phone").

At this point, the monitor has been connected. Let's click on "SMS" in the lower right corner.

At this time, the computer has found the contacts on the mobile phone for us, which are listed on the left and the short messages sent on the right. At this time, we click "New SMS".
