At present, many car owners have a strong awareness of installing gps tracker with temperature sensor on the car, and as the market demand expands, the demands for products will be more and more detailed. The traditional gps tracker with temperature sensor needs to be used with a SIM card, and now many people feel that the use of the card is troublesome, and they want a card-free locator. Then there is a question: is it better to use a plug-in locator or a card-free positioning?

First of all, let's figure out what the location of the SIM card in the gps tracker with temperature sensor is. Although it has been singled out and talked about in detail before, here it is briefly mentioned: In order to achieve the remote monitoring of one or more cars on the PC and mobile side, the positioning platform needs gps tracker with temperature sensor to send real-time location information, and the platform provides a series of derivative services for the owner of the positioning device according to the data, such as remote oil and power cut. Car gps tracker with temperature sensor to send out vehicle location information must have a network, just like, mobile phone has a network, you can use wechat to communicate with friends. The SIM card is the source of the location network.

Does the card-free locator break the theory? Does the locator work without network traffic? It's not! The positioner principle of the no-plug card is to integrate a traffic chip on the circuit board, which uses the company's traffic pool, which is equivalent to the company setting up an interface for the chip to receive traffic. It can be understood that the manufacturer is the SIM card "embedded in advance" in the locator, and the customer only needs to pay the subsequent time to use it.

In fact, the working principle of the two locators is the same, there is no big difference in essence. Moreover, the no-card locator is very particular about the traffic chip, and if some customers buy a locator configured with a low-quality traffic chip, the location information will be updated slowly or directly offline. In the long run, if you want to replace the chip, you have to replace it with the locator. Some people say warranty? You can also, but the process will be very troublesome, think about the electronic products you usually buy online need to return to the factory for maintenance, you can probably appreciate.

The traditional locator is the SIM card problem, only need to replace the card. However, the best thing about the plug-in card is that because the plug-in card is built into the flow chip, it has high waterproof requirements, and the water resistance of the locator is stronger than that of the traditional locator. However, whether it is a plug-in or a card-free locator, choosing a good brand is the guarantee of quality and follow-up service.
