1. Don't choose a GPS locator that is too cheap. There are a lot of locators for dozens of dollars on the Internet, but the subsequent platform usage fees and traffic fees will be very expensive.
2. Be sure to buy the 4G version. 2G is now being phased out gradually, the 2G version will not be used for too long, and the positioning is not accurate.
3. Be sure to buy products that are directly sold by the manufacturer. The after-sale service is guaranteed, the quality is guaranteed, and there will not be too many problems.
4. Be sure to ask about the usage fees and traffic fees of the platform.
