Which mobile phone can be located by SMS? It is worrying that the old man doesn't go home on time and doesn't answer the phone. They want to locate remotely and get extra points of satisfaction.

According to your requirements, there are two ways.

First, you don't need to change your mobile phone. Open the old card for base station positioning (approximate positioning), and open the positioning package, which is base station positioning. Base station positioning is not the same as GPS, but it can basically meet your requirements.

Second: you can use Baidu GPS watch, "a treasure network"

Current monitors include vehicle-mounted GPG, handheld GPS, GPS watches, GPS child locators and so on. But it is also roughly the same.

You can go shopping,

Generally, it's GPS terminal (around 400 yuan)+flow card (5 yuan flow package is open for one year)+software (see if it's free). The charge is different for each family, but it is generally 500-600.

In fact, the same is true of GPS equipment, mainly depending on its software, which is inconvenient to use. Is there any function you want? Of course, you can also watch two more. Try the software function and look at the map.

Auto parts city and GPS company can install and sell them, and they can also be found online.

You can search on a treasure network. The device I'm talking about mainly needs the software client, account number and password to be tracked in the background.

Honey, are you satisfied with my answer? Hope to adopt!
