Under what circumstances can a stolen electric car equipped with gps be found?

If the electric vehicle is equipped with a gps locator, if it still cannot be found, there are the following situations:

The first is disassembly, which will be displayed offline on the vehicle inspection platform.

Second, if it is shielded by shielding equipment, it will not upload the gps location.

Thirdly, the SIM card in the device can't be found without gprs traffic.
