To better understand the difference between the two, we also need to understand the sim card's "role" in the vehicle temperature tracker. The vehicle temperature tracker will obtain gps satellite data during use and upload it to the server for decoding. After being decoded on the server, we can view the location data on the application. So the most important thing in the upload and download process is the traffic, so this involves the sim card.
As you all know, it's impossible to surf the Internet and make calls without WiFi if your phone doesn't have a SIM card. Then you can see how important the SIM card's "status" is.
Now, though, there's a vehicle temperature tracker without a SIM card, and what a novelty it is, it also feels technologically sophisticated. The principle of the card-free vehicle temperature tracker is to integrate a flow chip on the circuit board, which uses the company's flow pool. So they set up a traffic interface for this chip to receive traffic from the pool. Thus, the vehicle temperature tracker can be located without installing a card.
However, while the card-free vehicle temperature tracker sounds very tech-savvy, they do have drawbacks:
1. Stability: If some companies use poor quality stream chips, they often go offline on the platform.
2. Maintenance is inconvenient: Once the chip fails, you can only replace it by sending it back to the manufacturer for maintenance. If the traditional vehicle temperature tracker traffic card fails, simply replace the traffic card.
Of course there are disadvantages as well as advantages:
1. After IM integration, the circuit board can be made smaller, thus making the overall volume of the product smaller.
2. Avoid the hassle of inserting the card into your mobile phone. (To that end, only a small percentage of customers find it easy to insert a card, basically just once.)
3, improve the waterproof and dustproof ability
Which is better, card-free GPS vehicle location System or traditional vehicle temperature tracker? Xiaobian still recommends the traditional card-in vehicle temperature tracker, after all, it is not very troublesome to install the card, and compared with the card-free GPS, the traditional GPS has been developed for a long time, and all aspects are perfect. Of course, this is the advice of Xiaobian! The specific needs also need to be based on your own situation and preferences.
