What do you mean, positioning requires SMS?

Positioning requires short messages, that is to say, in some cases, in order to obtain the accurate location information of equipment, short messages need to be sent to trigger device positioning. This way is mainly because in some old devices or specific application scenarios, devices may not be able to start real-time location services or obtain location information in other ways.

There are many reasons for sending SMS to locate, including the following:

1. Device limitation: Some devices may not have location service installed or enabled, or may not support other location methods (such as GPS, Wi-Fi location, etc.). ), so sending short messages to request the device to return location information has become an alternative way.

2. Network restriction: In some cases, the device may not be able to connect to the Internet or the network signal is weak, so the real-time location service cannot be used. As a communication method based on cell phone signal, SMS can still obtain location information under poor network conditions.

3. Special requirements: In some special application scenarios, such as monitoring equipment and vehicle tracking. It is necessary to trigger the device to send location information through SMS to realize the positioning and tracking of the device.

It should be noted that in modern smart phones and most mobile devices, more advanced positioning methods (such as GPS, Wi-Fi positioning, base station positioning, etc. ) it is usually used, so it is relatively unnecessary to send text messages to locate. However, for some specific devices or special circumstances, there will still be cases where SMS positioning is needed.

In a word, in some devices or specific scenarios, it is necessary to trigger devices to obtain location information by sending short messages. This way is mainly to overcome equipment restrictions, network restrictions or meet special needs. With the development of technology, modern equipment usually adopts more advanced positioning methods, and the demand for SMS positioning is gradually decreasing.
