Some locator sales merchants often claim that as long as the seller buys the locator, it can have the lifetime traffic free service of the locator.

So, how in the end are these businesses to achieve 4g vehicle gps tracker lifetime traffic free service?

1.4g vehicle gps tracker principle

First of all, let's look at the principle of GPS: 4g vehicle gps tracker to obtain satellite signals - > sent to the server through the network - > the server calculates the latitude and longitude and analyzes the specific location - > display it through the PC or APP.

It can be known from the principle that the main purpose of 4g vehicle gps tracker is to obtain satellite signals and send them to the server. And sending information is the need to use the network, that is, the network that needs a SIM card to send. So a 4g vehicle gps tracker without a sim card does not exist.

2. Free data cards are a scam

All the locators will only transmit data upward after the "traffic card" is installed, and if we encounter businesses selling locators that tell us that 4g vehicle gps tracker can be free of traffic for life, then consumers should pay attention to be vigilant.

The locator is just like our mobile phone, uploading and downloading data is a continuous process of generating traffic. Some equipment sellers do give consumers certain consumer concessions when selling equipment, such as: equipment and SIM card together to buy, send consumers the traffic cost required for a normal year. Consumers are equivalent to "free" access to traffic services within a year, but it should be noted that free use of traffic for a year and free traffic are two concepts, and today there is no equipment business can provide "free traffic" services, lifetime free traffic that is more bullshit.

If there are businesses that say they can provide lifetime free traffic services, it must be a lie.

Of course, some businesses may not directly say that their locator can be free of traffic for life. Some merchants may take advantage of the one-year free data limit provided by the carrier to advertise that their cards can be used for free forever, which is also deceptive.

After a year, the after-sales processing time of the equipment and card has passed, or the business simply "disappeared" and ignored people, and consumers have no choice.
