Ruifeng information consultation

Hello, you'd better consult the merchant for details. According to our experience, the possible reasons are as follows:

1. The positioning system may have expired and needs to be paid;

2. The SIM card in your car locator is in arrears or the traffic is used up, so it needs to be recharged;

3. Other reasons.
