Car friends who have an understanding of the car cat m1 gps tracker know that the locator needs to install a SIM card to achieve what we call positioning navigation continuous tracking and other functions. So the merchants claim that the free card is cheating consumers? No, this relates to how the cat m1 gps tracker works:

First, the role of the SIM card:

The cat m1 gps tracker itself does not require a SIM card. It is itself a complete system, as long as the locator is electric, can receive more than 3 satellite signals to achieve positioning. However, this positioning is a two-way process, that is, the locator receives information, and also sends its own positioning information through the device, and calculates the information sent by receiving and reading it, so as to determine the location of the GPS device.

If there is no SIM card, it is equivalent to no network, GPS information can not be shared with other devices, positioning platform software will not have your location information.

Second, the role of the platform

The platform is the medium of vehicle inspection and the centralized point of processing equipment data. Only through the platform software can the location data be analyzed into Chinese address, and the functions of historical track, electronic fence, mobile phone inspection and so on can be realized. Therefore, cat m1 gps tracker, SIM card, platform software is a triangle, the most stable relationship, indispensable.

What is the card-free cat m1 gps tracker?

The free card promoted by the brand is because the cat m1 gps tracker is basically a built-in chip card, that is, the chip of the card is directly welded to the motherboard when the factory is delivered, simplifying the trouble of users. Therefore, the so-called free card cat m1 gps tracker is not to buy it yourself, but "the wool is out of the sheep", and the purchase money has long been counted in the price of the locator. In addition, it should be noted that the merchant configuration card will generally give free traffic use for a certain period of time, and it needs to be renewed by itself in the later period, and it is generally charged annually, but this cost is far less than the network traffic cost that we are exposed to daily, so there is no need to worry about it when using.
