I bought this Anxin 360 last night, and to be honest, it doesn't work very well. Customer service is not good either. At first, I asked them if they could modify the bound mobile phone halfway, and the customer service said yes. As a result, I opened a monthly package with the number 10. I tied my mobile phone number first and tried it. Results When I want to change the bound mobile phone number, I am prompted to modify the bound mobile phone number, which only supports annual members. Shit. . . Didn't the customer service say that the binding number can be modified? Isn't that cheating consumers? The tracked mobile phone must start the software of Anxin 360, and the location of the base station is not successful at all. GPS positioning is still far behind, at least 100 meters. The software is also connected to GPRS, and the traffic is still important, which is far from what I need. It needs 10.
