Those who know the car battery powered gps tracker know that the tracker must be installed with a mobile phone card to achieve the location positioning and other functions that everyone refers to. Is the store's claim of free cards deceiving customers? In fact, I can't say the same, because there is a certain working principle of the battery powered gps tracker involved here:

The battery powered gps tracker itself does not need a phone card. It is a complete system in itself. As long as the locator is powered and can receive signals from more than 3 satellites, positioning can be achieved. However, these positioning is a two-way process, that is to say, the locator receives information, and also needs to transmit its own positioning information through the device, so as to clarify the location of the battery powered gps tracker.

If there is no mobile phone card, it is equivalent to no network, the information content of battery powered gps tracker cannot be shared with other devices, and the positioning platform will not have your location information content.

The service platform is the carrier of vehicle checking and a work area for processing equipment information. Only by relying on the service platform can the positioning information be analyzed into Chinese addresses, and functions such as historical tracks, electronic fences, and mobile vehicle checking can be realized. Therefore, battery powered gps tracker, mobile phone card and service platform are a triangular relationship that depends on each other and are indispensable.

The free card that the store usually advertises is because the battery powered gps tracker manufacturer has already embedded the phone card, that is, the chip of the card is directly welded to the motherboard during production, which simplifies the operation steps for customers. Therefore, the so-called battery powered gps tracker without the matching card does not need to spend money on its own, but "the wool comes out of the sheep", and the purchase money is already included in the price of the tracker. In addition, it is important to note that the cards provided by the store usually give free data usage for a certain period of time, which must be renewed by yourself in the future, and are usually charged annually, but these charges are much lower than the data traffic charges that you usually know about, so Don't worry too much when using it.
