We all know that the use of 2g gps tracker needs to be used with a data card, but many people will talk about confusion, why does 2g gps tracker need a data card?
1. The role of flow
Why does the car positioning system use traffic? On the premise, you can first pay attention to the principle of 2g gps tracker. The positioning terminal is a terminal product with a built-in GPS positioning module and a mobile communication module. It is used to transmit the positioning data obtained by the GPS positioning module to the server using the mobile communication module, so as to complete the remote viewing of the terminal product on the computer or mobile phone, that is, the car. Location. Therefore, just like on a mobile phone, you need to use a card with an Internet data package enabled to support data transmission.

Second, the classification of traffic cards
Under normal circumstances, the cards required for the car positioning system are divided into three types, traffic cards, IoT cards and mobile phone sim cards. The data card, in short, only provides the data package, and the functions of short messages and calls are not available. However, with the continuous improvement of everyone's requirements, the data card has an additional package content of 3 short messages per month, which is not supported for the time being. Call function. The IoT card is the most used card in our car positioning system. It is usually more affordable to buy it with the product. The use of the IoT card only needs to enable a monthly data package of 5 yuan and 30M. The mobile phone sim card is a commonly used card on everyone's mobile phones. It has the functions of traffic, making calls, and short messages, but the cost is relatively high.

3. The number of traffic used by the locator per month
Special attention is that no matter what type of traffic card is used, it is necessary to ensure that the card is not in arrears and does not stop, so as to avoid affecting the normal use of the product. Generally speaking, GPS locators are divided into two categories. For example, Concais GPS locators have wiring type and installation-free type. The flow of the two is not the same. But the common point is that the monthly traffic is very small. The fixed frequency positioning only needs a few M per month, and the real-time positioning will not exceed 30M.
