This not only provides closure for victims but also acts as a deterrent to potential thieves.
While there is no single "magical app" that provides instant real-time tracking, police use a combination of official databases, carrier-grade software, and specialized surveillance tech:
In the age of smartphones, every mobile device carries a unique, permanent identifier: the International Mobile Equipment Identity (IMEI) number. Unlike a SIM card or phone number, the IMEI is hard-coded into the device’s hardware. For law enforcement agencies, this 15-digit code has become an invaluable digital fingerprint, enabling investigators to track stolen property, locate suspects, and link criminals to their crimes—even when the suspect changes their SIM card or phone number.
Here’s a professional write-up on how police use IMEI tracking software in investigations, written for a general or educational audience.

However, if the phone connects to Wi-Fi, it may still be traceable, and specialized spyware tools (used in high-level intelligence operations) can sometimes activate features even without a SIM.
However, there are also challenges and concerns:
